Fender Hot Rod Deluxe Repair - No Power, Won't Turn On

  • In this video, we'll tour a problematic Fender Hot Rod Deluxe. This one would not turn on at all. I tested the power transformer and had to remove the terminal leads to do it. Upon reattaching the leads, the amp came up fine. Unfortunately, this did not fix the underlying issue. The problem ended up being a bad solder joint on the input surge varistor. I also go ahead and replace a couple bad-looking caps and lift the power resistors off the main board.

    We are often asked to work on these amps. Generally the client doesn't have the budget for a full re-engineering, so here are a few things that have worked well in the past to at least keep them alive.
    All stock electrolytic filter caps must go. A bit of acrylic caulk between the replacement and the circuit board is a must.
    Next, reflow solder on all tube sockets (the amp runs very hot and those connections can fail).
    Ditto on the big power resistors.
    Be aware that the inflexible ribbon connectors are going to break. Replace them with stranded insulated wire.
    Get rid of that PC mounted input jack. I've Installed chassis mounted switched jacks and used a shielded cable to attach to Pin 2 of the first 12AX7. Don't forget the 68k grid stop resistor.
    Not my favorite Fender either, but in fairness we've all seen worse.

      A lot of modern input jacks are plastic because the don't want to ground the jack to the chassis.. instead they use a common star ground point. Old amps were noisy because there were multiple ground points that cause current loops. The input jacks. the speaker jacks the send/recieve jacks all grounded to different spots and the ground path was a mess.
      Nothing wrong with pcb mounted input jacks.

    • @green323turbo

      Howard Rose, so whats your logic behind changing all the stock electrolytic filter caps ? Why not just diagnose the bad ones.. or do you not know how ?
      If most Caps have lasted 30 years.. they will probably last an other 30 years. Sounds like your shop is a parts changer(.. bill inflator.)

    • @Alex-jq5ft
      @Alex-jq5ft 7 ปีที่แล้ว +6

      You're right, but non of these Hotrod-series amps are 30 years old. I believe he's saying that the caps are very likely to go wrong because they're poor quality, so replacing all of them is somewhat of a preventative measure.

    Another easy thing to check besides the fuse is the power switch and the power cord itself with a continuity check. Of course I'm adding this suggestion to viewers that are not electronically inclined and not to disrespect Brad's technical savvy. I'm a tech geek myself, so I enjoy watching troubleshooting videos. I like to stop the video, figure out what might be wrong and see if I'm correct. A great learning experience. Great vids Brad.🔧👍

  • @MrDiscomfortzone
    @MrDiscomfortzone 2 ปีที่แล้ว +1

    Very good video. As a 40 year veteran of electronics instrument repair, I would have let the amp cook for awhile after re-soldering the R11 joint. The iC caps shouldn't have been replaced until the R11 joint was confirmed to be the cause of intermittent shutdown. It's best practice to confirm a repair is solid before doing preventative maintenance. Just a thought...

  • @backlineguy
    @backlineguy 3 ปีที่แล้ว +1

    I agree about the overdrive channel...I've replaced the first preamp tube with what I think is an AT7 and this cuts the output by around 40%, and actually improves the sound of the OD channel...simple mod...great videos, thanks for sharing your experience and knowledge

    This is the most popular PRO TUBE AMP EVER SOLD. Yes you read that right. Anyone who plays a lot of LIVE GIGS, knows what I'm talking about. This amp is in more back lines in more clubs, bars, theater's and halls, all over the world, then ANY OTHER AMPLIFIER. With a few mods, this can be one of the best, clean, high headroom, pedal platform amps, you could ever play through. Don't ever sell them short. You can pick one of these up used, for $300 or $400 hundred bucks, put another $200 in mods and , say a nice Cream Back, or a Vintage 30 speaker, and it sounds AMAZING, and is a dependable workhorse of an amp. I've gigged with one for over 10 years now, granted it's not my only amp, I play through two other Fenders and a couple of Dr Z's too, but I use it a lot and it really can be made into a very nice little amp.

    Nice thorough work on a tough piece. I recently repaired a Peavey Delta Blues combo... I had everything beautifully fixed up with minimal trouble - a near miracle in itself! All was back in the chassis and tested again - everything A-OK. Put the whole thing back in and button it back up - Power tubes wouldn't light... somehow broke one of the board jumpers JUST putting the chassis back into the cab! Worst part is, I didnt even move the board after reinstallation and testing. If that's what a miniscule amount of bumping can do? sheesh...

With a Vox power supply, blackface clean channel, fender deluxe reverb circuit, valco term circuit *thank you for featuring it uncle doug*, and high gain second channel more Marshall like with dual tone stacks. I’m going full mad professor after years of modifying that delta blues to make it sing.

    First off I want to say how much I appreciate the time you put in to give us these interesting videos. There was one thing that had me yelling at the screen on this one though. Am I the only one who noticed the voltage fluctuating about 150V OR MORE on your DVM, while you were messing around with the lamp!!!??? I know if you rewatched this video you would have yelled out DOH!! Your chop stick method would have found this problem the first timeI think. I know I have had a bad day or two in my career as a tech, luckily no camera was there to pick it up 🤫

    I owned one of the 410 models not long ago. I liked the amp while it was working properly. One thing that is demonstrated in this video, and is most definitely of note should one of these strike your fancy, is the fact that Fender obviously cut corners every way they possibly could. What you end up with is an amp with the great Fender clean tones a lot of us love, but be aware you are probably going to be racking up some service bills, especially if you're gigging regularly. Oh, and that "More drive" option does indeed sound like shit.

  • @Alex-jq5ft
    @Alex-jq5ft 7 ปีที่แล้ว

    I work in a guitar store in the UK and we have so many issues with these amps. The 3rd gen Hotrod amps seem to have been getting more and more unreliable as the years have gone by, and at the moment we literally send about two thirds of our Hotrod III stock back to Fender because so many of these amps don't work straight out the box.

  • @mrGoesto11

    Good catch on the fuse holder. Can you explain how you found the primary and secondary wires on the power tran. All the IC caps need to go and the sockets need to be reflowed.

  • @odustbrown1836

    Same thing happened on my Blues Deville. While I was trying to figure out what would cause that part to go bad, I happened across your video. I put my finger behind the board and wiggled the thermistor.......... Sho' nuff, it was loose. Good stuff! You saved me a lot of worry.
    I bought this amp for $65. Guy had pulled the tweed off and spray painted flat black over the remnants of the contact cement. It was missing a few parts, handle, glides, etc. I put about $60 into tweed/parts/supplies, and recovered it myself. She's back in action now, and worth a lot more than the $125~ I've got in it.
    Sure thing Mister, I'll take your garbage.

    These amps can be a nightmare to repair most times.I've repaired what I'd think was the fault and played/tested to ensure this only to have them returned for further surgery.The "evil Twin" is another bad one.Change main jacks, re solder all ribbon cable conections and check for continuity as they tend to break inside the insulation and will cause countless hours of hair pulling and loss of income for a repairer.Check and tighten all other cable lugs and change electro caps. Good only if used as anchors.

    I had a Hot Rod DeVille come in with bad solder joints on the caddy for the power transformer fuse, which was intermittently preventing the amp from turning on. PCB constructions means suspending disbelief.

    • @wildbillhackett
      @wildbillhackett 7 ปีที่แล้ว +1

      Nothing wrong with PCB construction at all if you do it right. Use nice thick PCB for one thing. Don't mount jacks and pots to the PCB board. That's the biggest part of it. I have an older (1995) Laney VC30 that's made just that way. I'm not nuts about the sound (too Vox-ish for me), but many people have said that if you're going to use PCB, that Laney is one of the few that did it right, at least back then. Unfortunately, they've gone to the PCB mounted jack and pots now too.

  • @watkinscopicat

    i would also recommend swapping in a pair of 6v6 tubes, you'll need to adjust the bias, but it sounds sweeter and less deafening, also a 12atz/ecc81, in 1st preamp sorts out the sudden volume jump problem.

    Hey everyone, I'm repairing my own Fender Hot Rod which stopped working abruptly yesterday and won't power on at all. I checked the fuse with a MM and it's fine ! I proceeded to test for continuity between CP3 and CP4 just like The Guitlogist did and I cannot get any measurement (it just says OL when measuring ohms, and it doesn't beep when testing continuity). Should I assume that my amp's power transformer is dead ? If so, can the PT just fail on its own or does it have something to do with another part ? I had just replaced the tubes and swapped all three original 12AX7 for Electro Harmonix 12AT7 tubes (the power tubes are SOVTEK 6L6WXT), could that have hurt my PT ? I thought you could use any type of ECC83 in the V1, V2 & V3 without any trouble but maybe I was mistaken (the amp had stopped working during rehearsal but I believe it still had power because the light was on, which is why I decided to change the tubes in the first place thinking they were the reason why I was not getting any sound)) !
    Thanks a lot for helping !

    I see lots of techs here, so I hope you guys can give the answer to this question that's been bugging me.
    It all began when my rig got noisier and noisier as I added pedals. Acted as though my guitar wasn't grounded, but I'd take it to the music store and it was absolutely quiet. So, I went to Home Depot and got a circuit tester for all the outlets. What I discovered was that I had no grounds in any of the bedrooms or living rooms, only in the bathrooms and kitchens (hmmm.... where there's running water). Now, this apartment building was built in 1959 or 1960, so for sure it's been converted from 2-prong to 3-prong. That leads to my question.
    How come all of today's transistor/digital electronics don't use a 3rd ground prong, just the neutral side for ground? My Fender tube amps all have 3 prongs but my Roland and other amps only have 2 prong. What gives, please? Why doesn't my TV, for example, require a good ground?
    Thanks in advance!!

    I have the 60watt 2x12 version. But mine is in a head cab, its had a LOT of work done. That is the problem with these amps is for your average person it makes no sense to mod this thing and just buy a different amp imho. But i got mine years ago for next to nothing and i wanted to experiment and the amp sounds pretty good now. Luckily the one i bought had no damage yet and i was able to catch problems early enough. I only use the clean channel, but one of the mods really helped change how the drive channels work. Still not enough for me to like the tone of those channels. Thanks for the video :-)

    • @ctcards2636
      @ctcards2636 ปีที่แล้ว

      Those two rectangular resistors in the middle of the board towards the tube sockets for the power tubes is one of the areas that can ruin these amps. They are touching the board. Replace these and make sure you keep them off the board and the problem is solved. But ive seen a lot of these amps from the Blues Jr, Deville, Blues Deville etc have really bad damage here. Also those quick plugs are notorious for burning up the board as well. Theres some real cracker jack stuff going on in this amp and i am shocked how much these are new now. Thats a lot of money for this amp imho.

    I use this amp as a clean amp and I think it's a great sounding , clean tube amp, after a few mods of course. It takes pedals very well and especially ran in stereo with a plexi or Marshall it's the best of both worlds. I've had one for years now and it still runs strong. Sure there is better amps out there, for me it's been a dependable workhorse. Maybe I just got a good one. I'd rather have a Super, but the Hot Rod works fine.

      The Guitologist I have quoted repair costs for fried circuit boards and broken tracks/pads that are more than those amps are worth.
      I don't charge a whole lot for labor because I genuinely like to do this kind of work. I'll generally charge about $250-$300 for a full rework.
      I reuse all the parts I can and build custom turret boards for whatever circuit(or two) they want. Obviously adding tube Reverb adds a bit more because those digital tanks don't have the right impedance.
      BTW, I have yours and Uncle Doug's videos in repeat whenever I'm working on guitar related things. Thanks for all the great (and sometimes obscure) videos. Stop showing off all of those great Valco amps, it'll drive up the prices!

    Brad, I've just converted my Fender Blues Jr. from a pcb to a handwired Hoffman turret board and tube board. Everything sounds good except I've noticed that if I have the preamp volume up and the master all the way down, I still hear signal. It's at a low volume but still very noticeable and the tone is thin. Like a cocked wah. I'm guessing it's something to do with the grounding on the master volume pot. Any ideas or suggestions in where to start investigating? Appreciate your insight.

    • @TheGuitologist
      @TheGuitologist  7 ปีที่แล้ว +1

      It's not unusual to hear a little bit of signal with a Master all the way down. Most pots will still have some small R, even with the wiper all the way down. You can test that by putting your probes from wiper to ground leg and measuring the R with the Master all the way down. You will probably still see some R there. If it's real low, like under 100 ohms, I wouldn't worry too much. Then measure from the ground leg of the Master to the main ground point on the chassis (where all your power caps are grounded), and see if there's any R to speak of there. I doubt it's an issue and I doubt you've done anything wrong in assembly. Hoffman has a forum though if it's too annoying, you might find more help there.

    Hello there. My name is Abby and I was wondering if you can help me with a Fender FM212 DSP that I have tried to repair without luck. The problem that I have with the unit is as follow. Unit turns on but has no sound at all. I checked the amp section and all voltages are fine. I have realized that if I press the channel select button it won't change channel. I have been searching for the schematic diagram all over the internet without luck. Any assistence will be appreciated. Thank you

    These amps have a reputation. Fender really needs to spend the few cents more for good caps those IC caps are trash. They fail and when they do they toast the board. Those resistors being right against the board can't cool and also toast the board. The lead free solder can be a pain also.
    These amps don't deserve the Fender badge at all

    So for a while my Fender HR Deluxe 3 started buzzing, badly. I changed the tubes with far more expensive ones that there were already there, but the buzz still remained as it had been. The sound of the guitar does go through, but the buzzing is so loud that it distorts it in a horrible way, especially on drive. I need immediate help please. Thank you.

      I used to be a Mesa dealer and liked the Mark V overall. Newer Mesas are hard to work on, lots of switching and stuff in those, but the 5-year transferable warranty is hard to argue with. I have not played the smaller Mark Vs. The reason I like the Mark V is because the tone is about the furthest away from the Dual Rec overdrive tone, which I'm not really a fan of.

    I bought a brand new hot rod deluxe and a blues jr. in 2012. The blues jr blew up in one week and in about a month one of the push button switches quit working. This is why I have been trying to learn how to build one. I'm tired of getting ripped off by amp, pedal. and guitar companies. I have built a few guitars. I know what it cost. I have a friend that has built pedals. They over charge for all of this stuff. People on you tube, doing reviews get mad when I say these things, but it is true.Pedals for sure. It does not cost hardly anything to build a pedal.I understand the prices of some amps. They over charge for guitars, big time. Shane on in the blues said someone was copying the mad professor . Blue delay and that it was the same pedal except the paint.He said that was a shame. The shame is-Someone built the exact same pedal for 50 dollars that the company that owns the pedal to begin with charges 2 or 3 hundred dollars for the pedal. This is what the shame is.If I see one more pedal review, I think I will puke.I know what I can get the parts for to build a guitar and these companies get their materials a whole lot cheaper than I can.The last body blank I bought at the local sawmill was 27 dollars (ash) (kiln-dried)and the hard rock maple for the neck was 20 dollars for a board that I got 3 necks out of. As long as people keep paying these crazy prices gibson and fender will just keep going up and pedal companies(the biggest rip off) will keep laughing at you, all the way to the bank. And oh, one more thing. They will get to the bank in their BMW that you paid for!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

    @glenwhatley4125 3 ปีที่แล้ว

    Better more permanent solution that has proven itself for the overheating resistors in the brute force + - zener 12Vdc supplies is to replace the 470 ohm supply resistors to the zeners from 470 ohms to 750 ohms. Stick with me on this:
    The only devices in the HD Deluxe that those supplies feed are the dual op amps that deal with as i recall channel switching and reverb.
    Those opamps draw at max less than 10 milliamps or so ea.
    The amount of current required to keep the two zeners from dropping out of the zener mode is a whole lot less than the amount of current driving those zeners with the 470 ohm resistors.
    Increasing the value of those resistors to 750 ohms including the miniscule amount of current 'stolen' by the two opamps is negligible compared to the current keeping the zeners saturated or as an instructor i had once put it: it's 'Flyshit in the Pacific Ocean'.
    So with the 750 ohm resistors supplying more than enough current tio keep the zeners saturated will not be affected by the small current taken by the circuit.
    You won't even need to stand them of the board. They barely get warm.

    • @TheGuitologist
      @TheGuitologist  7 ปีที่แล้ว

      The solder joints in these are prone to this problem, but it probably wasn't cracked from the factory. That probably came from being jostled and from inferior solder.

    • @rickr7333
      @rickr7333 7 ปีที่แล้ว

      Bad solder joints like this are caused by corrosion on the leads of the component. The corrosion causes the solder to not bond properly. The main cause of that corrosion is poor storage of the component, such as, not storing in a temperature and humidity controlled environment. This is a common failure from low cost production facilities.
