Here on eBay. One of the many red-headed step-children of Ted McCarty and Seth Lover as they tried to sustain sales of nearly a dozen or so models at every price point including amps aimed at the accordion market ... where the 'Maestro' line got started. This GA2RVT is the tweed GA19RVT Falcon taken a couple of steps further ... farther?
The auction amp:
From the back:
The pic with the cleanest tolex. The footswitches on all the tweed-era models were made from blocks of Philippine mahogany and can be refinished to perfection:
And from the side:
These are file pics of another GA2RVT that sold a couple of years ago in the $1,200-$1,300 range:
Another view of the front:
From the back including all the original knobs:
The GA2RVT uses 4 6EU7s in the preamp and a 12AX[U maybe?]7 driver; twin 6V6s out with a 5Y3 rectifier ... about 15 watts. The tweed GA19 used one less 6EU7. The auction amp is fitted with a Jensen C12R ... the GA19s had P10Rs ... P10Rs because the speaker bell on a P12R would physically conflict with the tubes ... the ceramic magnets on the 'C' series Jensens are shallower and don't hit the tubes.
Schmatic here (at Schematic Heaven's 'mirror site' ... can take a while to load) The reverb circuit in the blue box is the same as the GA19/GA30/GA77 and Fender on-board designs ... two tube sections ramping up the signal strength to drive the reverb transformer and can. The tremolo circuit in red is the same as the GA18 and other tweed and Crest era amps; very breathy and organic. Finally the GA2RVT borrows a filter from the GA20T/GA40LP design ... in magenta ... thought [by people who actually know about these things] to be a filter to damp low frequency oscillation especially if the tremolo is kicked in. My GA20T has the same R/C array and I've experimented with bypassing it ... the amp can get a little rowdy.
According to the seller: "... it does have both reverb and Vibrato, but neither are currently working. I suspect the footswitch has a disconnected wire, but I could be wrong. " I suspect he's full of it but whatever it is and no matter what you see, these are pretty simple circuits to troubleshoot. It has newer caps but seller doesn't mention whether the power cord has been upgraded ... can't tell from pics ... can't tell much of anything from the pics.
Not sure what Gibson/Maestro amp model she's using but I know many of you play your electric rigs in church ... well so does Sister Rosetta Tharpe.
If this isn't what you're getting out of your rig, you should bidding in this auction. :wink:
