Amp Fixed

I had bigger plans for this blog, but as it turns out, fixing the amp was a lot easier than I thought it would be.

Standard warning. If you're going to try this at home discharge the filter caps first. If you don't know what that means, ask someone who does. There are lethal voltages past this point.

After cleaning the surfaces with some citrus cleaner, I noticed that one of the screws appears to be non-original, (a square head), no biggie.

Opened up the chassis to find much of my anticipated work done for me



The original filter capacitors have already been replaced.





As have some of the other components inside.



More chassis pics.



























So what was the problem?

It turns out the last person to work on this amp must have take out the tubes and when he went to put them back he switched the position of the 12AX7 and 7025. Lols.

New Amp Day

So all the time that I spend checking craigslist has finally paid off. Picked this up a few days ago. A 1966 Blackface Fender Deluxe Reverb.



Paid a little under market value because it has some noise issues, will explain more with a sound sample later. From what it looks like, it's all original except for the 3 prong cord mod done in the 80s? They guy I bought it from got it from his friend who we're assuming is the original owner. First owner was based out of the B.C interior. He gave it to the person I bought it from when he went on tour, and apparently never asked for it back, which was some time in the 80s. The current owner barely used it because he's more into metal, would rather have a dual rectifier.



The Tube Chart found glued to the left wall inside the cabinet. According to Fender the P indicates a production year of 1966 and the F indicates a production month of June. So it was produced around June 1966. Not sure about the '54'.



Serial on the chassis A1xx81. According to this, serials from A12000 to A19000 belong to 1966.



If it'd said "Fender Electric Instruments", then it'd be pre-CBS, (~1965 or earlier).









According to this, we're looking at the stock Oxfords, made in the 12th week of 1966.



Original stock RCA tubes.







As for the noise I've include a small audio sample. It appears at the beginning and around 17 sec.

Introduction

So this blog will follow me through my journey of owning and fixing up a 1966 Fender Deluxe Reverb. A little background. Im an upper year university student taking electrical engineering, however by no means does that mean i know what i'm doing (both in terms of electronics and amps in general), hell i'm not even that great of a guitar player. Half the reason why i bought the amp is because I wanted to use it to get experience fixing up amps. The amp i have is pretty much all original and will no doubt need some maintenance and repair to get it playing as well as it's reputation says it does. Feel free to correct whatever inaccuracies I write. Like I said, i'm still learning.
