I have a pair of amps that need some help; '72 Deluxe Reverb and '72 Vibrosonic Reverb. Who's the best? I'm in the northwest suburbs of Chicago, about 20 miles out of the city. The Deluxe has a volume drop on the Vibrato channel, and could use a checkup (it had new filter caps when I bought it, I added a three-prong cord). The Vibrosonic had the reverb die (I resoldered a broken lead inside the tank when I bought the amp, it may have broken again), has had some minor mods done that I would like undone, put a variable negative feedback in the master volume hole, and get the noisefloor/crackling to go down/away. It also has newish filter caps, as well as a bunch of changed caps and resistors. Also, the tremolo is intermittent. So who should I contact? Who do you like? I'd rather avoid shipping at this point, but may consider it. Thanks!
