We’ve repaired hundreds of vintage Fender amps, and it’s always a pleasure to get these classic amps back in tip-top working order.
It’s a testimony to Leo Fender that so many Fender amps from the 1960’s are in use today.
Here’s a picture of the inside of a vintage 1960’s Fender Blackface Deluxe Reverb we took in for repair.
The amp was working, but would intermittently cut out at higher volumes.
On further inspection, we found that one of the ground wires from the eyelet board to the brass ground bus had become unsoldered.
Not the best photo!
Anyhow, the mechanical vibration during use disturbed this ground wire and hence the intermittent signal.
I’ve seen this problem on several Blackface and Silverface Fender amps.
Now I routinely check the soldering to the ground bus whenever I’m looking inside a Fender chassis.
Of course, resoldering the wire solved the problem!
