Thanks for the info. Turns out I got it working with a little sand paper and WD-40. I appreciate your info. I kind of assumed it was something more technical just because of the age of the amp. Thought it might of broke over time. I'm glade it was simple like that though. This being an older style bulb though, is it even possible to find these anymore? I know it will go someday, it won't hold up like an LED would.

Another quick question regarding this amp. One thing that really bugs me about it is that the power light doesn't work. So it could be sitting turned on and you can't even tell. The bulb itself works, and I've found that if you wiggle the bulb around it lights up. So it's something to do with how the bulb sits in the jack. Is there any hope for fixing this? Is it possible to get replacement parts for this anymore? Any ideas?

Before I start ripping this thing apart I was just wondering If anyone could explain what I'm looking at underneath. I took a picture and labeled the parts im curious about with numbers. Number 1 I believe is where I need to go to get the the filter caps. I'm just curious, What the other parts are. I can tell you guys have a lot more knowledge than I do, and I'm working on growing mine. So I thank you for your patients and assistance. I admit fully understanding this amp is a little over my head, but I'm trying to learn as much as I can and get a good understanding of this amp before I start taking things apart.

UPDATE: I took off the cover and found the filter caps, tested them with a multimeter all of them are showing 15V. Is this normal after discharge?

That schematic is very helpful, and all the information you guys have given is much appreciated. I think I have enough understanding of how to do this now. So my last step is locating the parts to do it. Do I need to make sure the caps I buy are also electrolytic? Or are there other types of caps that would be fine as well? Anyone have a recommendation as far as brand/reliability?

  The question is whether you want to replace just the electrolytic filter caps, or all electrolytics.

I did already know about the filter caps underneath, but I was under the impression that any cap in the amp that was electrolytic was worth replacing after such a long time period as this. I'd like to hear what you guys think about that though. My overall goal is to have an amp that still sounds good and can hopefully continue to last a long time. So if replacing more than just the filter caps would be beneficial than I'm fine with that.

What kind of cap is the blue ones? What causes them to go leaky?

Not quite sure which schematic/layout to post.  Does your amp have a "boost" pull switch on the volume control?

It doesn't have the boost switch. I believe that was added the year after mine.

I appreciate the information you all have provided. It's answered a lot of my questions.
I am aware the dangers exist and I don't plan on trying anything without research and precaution.

I believe It would work. The pin layout, and everything looks the same. The metal sleeve you mention doesn't make a difference, they will both function the same. The only real difference is just the barrel part of the jack sticks out the front more on the newer one. I don't think that would be a problem though.

To start off, I just joined this forum because I have been growing in interest in amplifiers. I went to college for computers, got interested in hobby electronics, started playing guitar and soon after wanted to get inside the amp and look around. That's my story, now to the question.

I just got a hold of a Fender Deluxe Reverb Silverface amplifier that I believe to be from 1976 after some research I did. It's been sitting unused for the past 30 years. I've read quite a bit online about how electrolytic capacitors go bad over 10-20 years, so by 30 years I believe they probably need to be replaced. I'm not an expert with electronics, but I believe I have enough knowledge to work safely inside an amp. I have quite a bit of experience working with soldering onto circuit boards and such, and although it's a little different on these older amps, I'd rather gather the knowledge and do the work myself, rather then pass it of to an unknown amp tech. I believe it should be fairly straight forward. Identify the electrolytic caps, read their values. Then buy equivalent caps, and solder them into the same place.

My main question to start out with, is does it matter what kind of caps I replace the old ones with? Do I have to replace them with electrolytic caps, or would another type of cap with the same values work as well? What are some good brands to go with? What's a good place to find them?

This is a link to all the pictures of inside my amp. Am I correct that all the large blue caps, as well as the white mallory caps all are electrolytic and should be replaced?

I'd appreciate any feedback, and I would like to thank you ahead of time.
