How to change filter capacitors Peavey classic 30 combo guitar tube amp

  • Another Peavey Classic 30 amp with leaky power supply capacitors. It is quite the job to replace these caps due to the 3 piece circuit board, limited access for component maintenance. If you have to change a defective cap, make sure to change them all. Save a revisit. It is a time consuming job. Best thing to do is take your time, double check your work. I recommend the F&T 500 volt caps for this task. Don't cheap out. After completion, these are actually pretty good sounding amps. Many bands use them for recording. Their only downfall is the PCB's cannot stand up to the road wear. Released in the early 1990's, its almost 30 years old! A great amp to give a second chance in life. I hope this info is of value should you decide to fix one.

    I don't know much about electronics. But with this great video, I proceeded to change all caps on my beloved Peavey Delta Blues amp which recently started to make loud noises. Everything went perfect on first try and my amp is now like new! Thanks Terry!

    Thanks to the video, I could open my PC30 which was roaming quite strongly, to change the 7 caps you indicated . Not so hard to do, but the work was successful, and I can us again my PC30 which was too noisy for my old ears...
    I could see that 2 of them were leaking, but I changed all of them and now can keep rocking.
    😀🎸🎸 Thank you from France for the great help!

    Terry, I bought one of these DOA about a year ago and thanks to your first video I was able to easily get it working. I use it every week at band practice. You are spot on when you say these things are delicate. You always nail things in your video... you got this one down to a science !!! Nice work ! Ron

    I ordered my F&T high voltage capacitors still having trouble finding the 50V 2200uf though I started this because my normal pot is really sketchy so I have to change that so I might as well recap while I am in there I did see two of the 22uf high voltage caps were leaking. Your videos are a huge help and great entertainment as well. Thank you for all your help.

    Very helpful, I just finished 1 of 3 pvc30s I am recapping tonight. Not that tough, my glue was easier than yours to remove for some reason. I did use a JJ 100uf 500v cap instead of the two 47s in parallel and I just wanted to give a heads up- those JJs are big boys and just barely fit under the chassis- I mean it is touching the top of the control panel. On the next two, I willl see if I can find an optimal placement that avoid that and post details.

    Awesome video thanks. I'm confused though, you showed the high voltage filter caps, then at the end you make a quick mention of the low voltage caps and change them. Are they also filter caps? I'm getting a steady 120V hum and think it's the filter caps. Should I replace the low voltage caps as well to try to fix this problem?

      James Brown said in an interview that when he was designing these amps, it was a battle of price, sound, features, and reliability. Hartley told him that the selling price would be $299, made in USA, and still expected a profit.
      So this amp is the king of price pinching tube amps back in the day.
      Now with advanced nano surface mount tech in China, this amp is a big old American dinosaur.

    Safety first!!!! I've made it to the 5 minute mark where you're poking pins inside this amp with bare fingers. Any chance of adding a capacitor discharge procedure to this video? 2nd, I think I hear SSD, maybe SD card read/write noise coming from the camera and/or recording equipment. Sure sounds like SSD noise to me. If it's a USB connected camera, you'll find this noise on the USB ground which runs right through the camera, right next to the power valves. Still, it'd be hard to isolate any faults if one is crispy from failing to discharge caps. My 2 cents...

    • @cobblewright
      @cobblewright 3 ปีที่แล้ว

      Yes. Why was the discharge of the caps omitted from this video? Seems dangerous and if an inexperienced person followed this video they may be electrocuted.

      What? I never heard that leaving your amp on for 24 hours could damage it!
      In fact I used my Fender EC VibroChamp as a space heater by leaving it powered up all winter once. My room was warm, the floor was warm. The amp is still loud and had no issues at all.
      Don't they leave the display amps and TV's on 24 hrs. a day, months on end in the salesroom floors?

    Hello I bought a used Orange Crush 20RT that has humming/buzzing upon startup with nothing connected to it. The hum/buzz is simply there, not affected in any way by what I do with the knobs. The amp only works with head phones in (the noise goes away and I can hear the guitar playing...I can manipulate the distortion, reverb, etc). Is it safe to say the amp may only need a speaker, or possibly a wiring problem related to the speaker? Thanks for any help.

    Can through hole filter capacitors in a power supply be improved by increasing them to a greater value to make the power supply quieter and more efficient especially in guitar amplifiers? Also how would I fatten up the sound of a Peavey VSS 20 and make the distortion channel fatter with more gain with less noise? Thanks.

    @tacotele6819 5 ปีที่แล้ว +1

    If you have the Chinese made Classic 30, the board and parts layout are completely different. They did away with the 3 piece board with a one-piece board, but they put in a ton of small filter caps instead of the larger ones, I guess so it would fit. I can't find a schematic for the new version anywhere.

All the tubes are lighting up , I had him to take a cord and plug into the effects send and a little amp that he has, to see ip it was the pre-amp or power amp side. Well it's not the pre-amp side , he was getting signal out the send side. I had him then take the chord and plug into the return side and the little amp send, no more sound than plugging into the amp like normal, I told him that it looked to me like the power amp had gone out.

      Mesa amps are half amazing and half horrific to work on. They usually make a lot of good choices like using leads to fly the pots rather than soldering directly to the board, but then they also have heat problems by cramming so much stuff together, they often require significant dismantling like this peavey, and they have so many switches, transistors, relays, and complicated circuit parts that if you end up with an intermittent problem, it can be almost impossible to ever find the problem, especially if it is heat related or a bad pcb trace. You win some and lose some with them.
