I have Princeton Chorus. I have had it for about 25 years. Hardly used it. Still looks brand new. I recently fired it up after years of none use. It had scratchy pots and it would cut out. I did the cleaning suggested in the video and everything works great, I used a contact cleaner from Home Depot, Clear Concepts. Thanks for posting
Thanks for the post. Great news. I’m glad the video helped and your Princeton is once again rocking!!! Enjoy!!!
I thought my amp was toast. I followed your video instructions and now my Princeton Chorus sounds brand new! Thank you! What a great sounding amp. I love it.
Someone gave me a red knob for fixing another amp of theirs I liked it soo much I'm using it as a pedal platform it sounds great through my 412 stereo using stereo chorus and stereo delay
Can’t believe I stumbled onto this video. I bought a Princeton Chorus off of Craigslist for only $75. Great condition but pot crackling was so bad the amp was cutting out. I thought I’d have to pay $$$ to have it serviced, but a $15 can of Deox and now it sounds amazing!
A buddy gave me one of these a couple years ago..an '88 red knob...just started playing it last week killer amp im turning it into a head right now stereo effects great pedal platform im using the clean channel anyways 🤟🤟🤙🤙
Thanks for sharing. It is a hidden gem. Amps should sound like this today!!! Enjoy and rock on!!!
I have a '94 Princeton Chorus that I haven't used in years. Unfortunately, when I recently plugged in to test it out, the majority of pots were very scratchy. However, it looks like your procedure should solve that problem. Thank you for making this video and helping out others with this amp!
Hello, You are most welcome! I hope you are able to get it back to it's original state. Keep us posted how it goes! These amps sound great! Be well! Rock on!
@@LUKESTRONG4LIFE Deoxidized the pots and jacks over the weekend and it sounds like new again. Thanks again for the guide!
@@je1279 Great to hear. Glad it helped! Enjoy the amp!
My favorite amp.I’ve heard people not liking the distortion channel but a I think it sounds killer especially when chorus is engaged.I have 2 of these amps.the second one I picked up for $60 bucks because the speakers connections were damaged probably from them tossing stuff in the back but I disassembled the entire amp and did some work on t and it looks and sounds amazing.
Hello and thank you for the post. I agree on the distortion. Whether I plug in my Les Paul or Strat, the distortion sounds great to me, especially with the chorus engaged. I add a bit of bass and cut down the mids for a distorted sound I love. What a great find at $60! Wow. So glad you are enjoying it! To me this is a hidden gem of an amp! Rock on!!!!
Thank you for the instructional video it was terrific I have the same amp followed your procedures and it worked perfectly. Thanks again Richard.
Thank you for the post Richard. So glad this helped you out. These are such nice amps. Enjoy yours!!!! All the best and Rock On! Be well.
Thank you so much for this video! I have had one of these since high school when I bought it new in 1997. My gain and volume knobs have recently gotten really scratchy and I was hoping I could find an easy fix without having to change out the pots. So happy to find your video!
Awesome. Most welcome. Hope it helps! Such an amazing amp!!! Rock on!!!!
I also have this amp. It was given to me and I'm at least the 4th generation guitarist to own it as no one could fix it. It would only make noise and no guitar signal came through. After disassembly I noticed the stains on the edge of the board giving me a clue as to what happened to it. Amps can't drink beer! I put a scope on the input jack board side and nothing was getting through so I replaced both input jacks. Now I had sound getting to the speakers but it sounded like crap. The pots were really touchy so I hosed them down with contact cleaner and it got better. After looking at the schematic I noticed the signal path goes through both sets of Send & Return jacks so I sprayed cleaner in them as well and pumped them with a 1/4" jack about 20 times each and spraying the while. This cleaned it up and now it sounds great. The point here is to clean those jacks as well! They're important. Also, do not try to jump out the reverb tank with an RCA coupler. It kills the impedance to the next stage and rails the amp creating terrible distortion. This was also done by one of the previous owners thinking he was troubleshooting. The reverb works great as well as the chorus. Not a fan of the distortion. I have $15 into it. Good luck.
Thank you for sharing! What a find. Thanks for the tips as well on the inputs. Greatly appreciated. Overall I love the amp. I agree though the distortion is not that desirable. I use it for clean tones. Thanks again and enjoy the amp!!! Rock on!!!! Be well. Brad
I have the exact same amp. Bought new about 20 years ago. My knobs are terrible. Especially my treble. I ordered that cleaner you used. Im going to get it fixed soon as it comes. I run an eq through the effects loop and its the best sounding amp i ever played. Ill never sell it.
Hi John, Great to hear you are enjoying the amp. I love mine too. Good luck wit the cleaning. I hope this video helps you. All the best and be well. Rock on!
Just picked up the same amp. Lady bought it new in 95. Took three or four lessons and put it away. Got the amp and a strat for 500.00. loving it so far.
guitarobot Wow. What a great find. It is a super sounding amp. Enjoy it!!!
@@LUKESTRONG4LIFE Thanks.even with the dirty pots it puts my other amps to shame. Can't wait to hear it all cleaned up. It looks like brand new. Owners manual, hang tags and all included. Thank you for your great video.
guitarobot Indeed a great find. I know you’ll cherish that thing. I am amazed too at how great these amps sound. They are a diamond in the rough. Keep me updated on how the cleaning goes. Rock on!
great vid friend...got my '88 sounding great! This amp is a sleeper and a gem. peace.
Agree! It’s a gem!!! Rock on!
I have one of these, a friend of mine gave it to me 15-20 years ago. It sounds great but the pots are super scratchy. Hopefully after I try this same cleaning, mine will be as clean as yours.
Thanks for the post. Please let us know how it goes! Enjoy the amp!
You g'head! Tx, all I needed to see was how to drop the chassis. Tx for this. And again. G'head! You def helped me out.
Thank you for the post. Glad it helped! Enjoy this great sounding amp! Rock on!
Man, thanks for this! I have a 20 year old Princeton Chorus sitting in my basement that hasn't seen any love in a looong time because of crackling issues. I keep meaning to have someone take a look at it, but life has a way of keeping that little todo on the back burner, ya know? After watching this, I immediately ordered some Deoxit D5, and I'm going to take a crack at it myself!
John Beck Hi John! Thanks for the post. My only recommendation is to take your time doing it. It will make a huge difference after the cleaning. I literally have zero crackling now. Please keep us posted and let us know how it goes. All the best and thanks again for the post. Be well.
How did ya make out ?
@@benallmark9671 Really did the trick! I have very little crackling now. There's still the occasional crackle on certain pots, but I figure I probably wasn't quite as thorough with the cleaning as I was with the others. Regardless, it is still greatly reduced.
It certainly saved me a lot of money and hassle over replacing them outright. :)
@@johnlynnbeck I’m eye bawling these because there’s one up on my local kijiji. Thing is , I need another amp like I need a hole in the head. I just ordered the new Princeton tonemaster and already have the deluxe and super. It’s like an addiction. The guy wants $300 Canadian and after seeing so many comments from guys that paid #75 ext I’m thinking I’ll let somebody else have it.
How many things are made in the USA? My Peavey heritage and my Princeton chorus are. American made equipment deserve love. And cleaning the pots, touching up the tolex, applying back to black to the chassis is such a rewarding and enjoyable task.
So true Walter! A great amp indeed. Glad you are enjoying yours. I still use mine often and without the crackling and popping, it sounds even better!!! All the best and rock on!!!!
Great stuff. I'm way overdue to do this on my PR82 (original owner). I need to get rid of move a I don't use it anymore now that I have my Helix going into studio monitors. Great stuff. Thanks so so much. Saved me at least $60-100 for amp shop to do it. I agree great sounding non-tube amp. BTW...you didn't mention the importance of staying away from the capacitors which retain high voltage.
Hello and thank you for the post. Glad the video helped out and thank you for the tip on the capacitors. Important to know! All the best and rock on!
Nice Job Sir.
Thank you. Greatly appreciated! Rock on!!!
"Vintage Amp" .. ouch. I bought mine new! Great video. Ordered some D5. My gain and volume pots are super scratchy.
Awesome. Let us know how it goes! Enjoy the amp! She's a great one! Rock on!
Thanks for that🙂
Most welcome! Rock on!
Thanks. Your video was super helpful and informative. Have you done a video on replacing the input jacks? Thanks!
Thank you! I have not done a video on the input jacks. I know there are some out there on TH-cam. All the best. Rock on!
Good video! That’s not a power supply. That’s your reverb tank. :)
LOL!!! :-)
Great video! I'm about to restore mine back to its original glory from when I bought it new back in the early 90s. One question - how exactly did you clean the input and effects jacks? Did you simply just spray cleaner into the actual input holes or are there ports on the backside, similar to the pots?
Tom P Thank you for the post. Yes. I sprayed the cleaner directly into the jacks and used a Q-tip to clean the surface and work the cleaner around. For me, it made a huge difference. The inputs are now clean and no static. Hope that helps. Be well! Rock on. Brad
Great video. Doing this today to mine in this snow day. Have you ever thought about replacing your grill cloth?
Hello and thank you for the post. I honestly have not because I guess I thought there were no replacements available. Do you know where to get a replacement grill cloth that would look authentic? Thank you and be well. Brad
Very good video. Thx for sharing. I have the same amp that also needs a cleaning. Do you have any recommendations for cleaning the circuit board of it is dirty when you pull it out?
Stacey Carlson - Hello and thank you for the post. I always use compressed air, but very gently and from a far distance. See what comes off with that. For dirt that wouldn’t blow away, I used Q-tips. I spray the cleaning on the Q-tip and gently wipe the board. It took about 50-60 Q-tips to clean the whole board. It took a while but came out great. Just make sure the board is completely dry before reinstalling. I let mine dry overnight and even put a fan on low setting pointed at the board to make sure it was completely dry. Any other questions, please ask. Let me know how it goes. Be well.
Awesome! Thank you for your response.
Olá, ótimo vídeo!
Me ajude por favor !
Comprei um amplificador desse na data de hoje, ele está muito conservado, porém alguns botões estão com ruídos. Gostaria de saber se posso utilizar WD.
Muchas Gracias!
That amp is clean. I picked up the same amp for free but it has some wear on it. Loud hum when turned on,turned out to be the capacitor solder joint was bad i fixed that. Would automotive electrical cleaner Work? RadioShack is no more were i live
Can you order it from Amazon? All the Radio Shacks are gone. Worse case is I would try the electrical cleaner. See if you can see what the ingredients are and compare them. PS - Great find!
Would this by chance work with a fender ultimate chorus that also has a crackling noise while playing?
@@htxxjayce Absolutely. I’m sure the steps are pretty close. Deoxit is awesome stuff!!! Makes such a difference!!!
I have this amp and for some reason it will jump from low volume to cranked by itself. Im wondering if cleaning these pots will help with this problem?
Hello. Clearly it would not hurt and worth a try. There could be corrosion on the volume pot that is keeping it from working properly. It could also be an issue on the circuit board, such as a bad capacitor. I would do the pots first and see if that helps. Then it may be time for a tech to look at it. You just have to weigh the cost to fix it versus the cost to replace it. Good luck. I hope this helps. Be well.
There is one on Facebook marketplace for $50. Would this work for buzzing when it is turned on.?
Buzzing when turn in could be a lot of things. Is anything plugged in? If so it could be the cord or the guitar, not the amp. For $50 it’s worth a shot. Clean all the pots and see what happens. It is a great amp!
@@LUKESTRONG4LIFE going to pick up tonight. I'll have to look it over at home. I think $50 is a steal.
@@johnschillace6634 Agree! Good luck!
Sadly my amplifier pots don't look anything like that on the back, it's a square with some tiny holes and not this circle with the entrance where you can spray the contact cleaner...
Hello, Sorry to hear. I am not sure what model and year amp you have, but hopefully there is a resource somewhere that can help you. Wishing you all the best. Please keep us updated if you can and let us know how it goes. Be well and rock on.
Good job, however, removing the handle was not necessary, but informative video !
Thank you Horace. It was a first time for me so I was not sure what to remove! Thanks and hope it helped!!!! Be well and rock on!!!!
Great video.
Thank you! Greatly appreciated. I hope it helped. Be well. Rock on. 🤘
Its fender trade mark .
Indeed. But still a great amp! Rock on!🤘
