Hi all!
Well it seems these blues deluxe's have a lot of problems. It started with the channels switching on their own. I had it repaired under warranty(about 10 years ago) and was told at first they cleaned the "relays", then a few weeks later I had to take it back with the same problem and they said they replaced the "relays". This worked for maybe a month or two, the problems started again, then eventually the amp just stopped working all together. The amp powers on, all the tubes light up, but I have no sound at all from either input, or channel. If I plug into the power amp in on the effects loop, I do get some sound, and if i strum hard I get a loud distortion sound. I've done some reading about it on here and other forums, and I saw what was mostly suggested;
TN94-7: For Blues Deluxes serial numbers prior to T-36620, replace R85 & R86 (330 ohm 5 watt) with two 470 ohm 5 watt Wire Wound Footed resistors (Fender P/N 041256). They specifically require "footed" resistors (the ones with the little bumps on one side) that will keep the body about 1/8" away from the pc board.
TN95-5: Check for value of R71 in channel switching circuit. Early amps have a 10K ohm 1/4 watt. If it is, it should be changed to a 100k ohms 1/4 watt.
I opened up the back of the amp and saw one of the 470ohm resistors had de-soldered itself. So I checked to make sure the resistor was still good, it was, and I re-soldered it. This however didn't change anything.
I'm unsure what these "relays" are that they replaced. Is it R71? I'm adding a picture here, is this what I need to check? I measured the ohms of it while on board and it is reading 6.24k Could this possibly be causing my problems?

This hasn't worked for me in about 10 years, I would love to have it back, so any help would really be appreciated!
Thank you,
Joe
