Yes, Jahn; that model is usually referred to as the 'Tweed' version ... not-so-subtle cosmetic (electronic?) ripoff of the Fenders of the period and this one:
GA19 RVT 'Crest' also on eBay. JP has one too; it's also a Gibson GA19 RVT Falcon - the 'Crest' model with the 'coat of arms' on it. The 'tweed' / earlier versions - like the one in my avatar, have a 7199 for a reverb operator, the later 'tweeds' and Crest models have the 6C4; oh those wacky Gibo engineers.
They also reversed the ID sequence in the schems; 7199 = transformer on left, tubes #'ed left to right, V2 = 7199 whereas if, as seen from the rear, the transformer is on the right, then V3 = 6C4 and the preamp tubes are numbered right to left. :evil:
Given the electronic zizz from the 7199 and assuming everything's ok, I'd guess the PR (1/2 12AT7 and 1/2 12AX7 for reverb) would be a lot quieter at idle than the GA19. Agree that the GA19 reverb isn't to everyone's taste. At the risk of rousing the Cheese-man JP, like cheese, reverb is particularly subjective; as much or more so than the 'voice' of the amp.
Dude #1: "This amp sounds great (like Gouda), especially the reverb!"
Dude #2: "You're crazy, it sounds like crap (I hate Gouda), especially the reverb!"
and so it goes......
Haven't done as much research as I'd like but I'd compare 60s amp circuits to Japanese rock gardens: one guy rakes the rocks, points at them and says: "Is a rooster". The next guy picks up the rake, scrambles the rocks around, and says: "Is a fish". Was re-re-re-re-reading Pittman's amp book last night; he was talking up the Magnatone 280; all this from the guy who is the Warren Buffett of tube amps mind you.
I guess my point is that by taking a handful of resistors, a few caps, some wire, and whatnot, you can scramble them around and get nearly any amp circuit you want - hear me out - there are always subtle things like the value of cathode bypass resistors and bias a little hotter or colder - flavoring the sound the way bacteria flavors cheese - but you always get an amp that doesn't sound exactly like the last one made from the same set of parts. Agree; weird, fascinating, fun, and above all, the unmistakable sound of low-power tubes.
My Falcon sounds as good as a Falcon can sound; better than something else? Who knows and I don't care; all I care about is that it sounds as good as it can. I have a GA18 in extremely good cosmetic and electronic condition (2 X 12AX7); same thing, it's Gibson (Cheddar) sound ... however, if you are partial to Swiss .... see above.
Glad to see your F30 move Jahn,
Very best regards Teleharmonium,
