As a bit of a project I took the case from an old solid state PA amp, added a two tube input circuit based on the Fender Deluxe Reverb but with one extra adjustable gain stage and a mid shift on the tone control. Add to that a solid state output stage and you have one neat little 20 watt head. Now looking to put a nice 1 by 12 cab under it to see how it goes!
This week a pristine Deluxe Reverb
Unfortunately it has no reverb. One of the transducers is open circuit and a real shame as this thing is all original.
I will put a new insides into the existing tank to keep as much as the original as possible.
Had one of Fender's more recent reissues in. The guy wanted a DI out so I just simply converted the extension speaker socket to a DI and relabelled it. He doesn't want to use the ext cab option.
Also a new set of output valves and a nice 5751 in the input and he is really happy with the sound again.
Nice amp, easy lug and can be really made to crunch if needed.
This week has seen two really nice Fender amps from the late 60's. A really nice blackface white knob Princeton which got a new set of power supply caps and a pristine Silverface Deluxe Reverb which seems to have a sad speaker problem.
It is amazing how these old amps keep turning up and the condition they are in!
A fairly well used 1988 Twin, red knob model with all the flash features of The Twin. Unfortunately it has two controls where the shaft is broken off, this will be major surgery as it will have to have the control board removed first before the pots can be replaced.
One is the reverb control the other the gain control. The gain control is a dual gang 1 meg pot which is going to be really hard to source.
Another Fender with valve blues. One output tube had chucked it in, a realatively easy fix but it seems that valves aren't what they used to be!
This one came in for a set of valves and a check over. New JJs in the output and Tung Sols for the preamp, bias all OK and working fine except for random crackles.
PCB style amps are a pain when they start this, can be tracking on the boards from dust and/or moisture, dry joints or components that are noisy. An almost impossible fix.
Resoldered a fair bit of the pcb that holds the valves and it quietened down dramatically, but only time will tell if it does the job..........................
Well an unusual repair. An old made in California Acoustic head that the muso wants to use as a bass amp. Only problem is the equalizer isn't working on two of the "bands" both at the bass end of course.
When I opened it up it was clear someone had removed some of the parts from the equalizer pcb. So rigged up some new coils and put them into servi
