Ever since I restored a 1955 GA-9 for a buddy, I've been interested in the Gibson 'tweed equivalents'. I see Mojotone has a GA-5-style kit for $500, and I've heard a lot of good things about how these Champ-alikes (there were many, I guess, not just Gibbys) can have a sweeter richer thing going on. And then there was this nice recent thread by @mjcyates who built a GA-5 on a Champ framework. OK, I know, I need another amp like a moose needs a hat rack (a moose who already has a number of hat racks). But, hmm, one of my hat racks is a 5F2a I really don't play all that often. Looking at the above build thread, and the GA5 schematic, and this page about interconverting Champs and GA-5s... I realized the 5F2a is already well filtered (32-10-10 instead of the GA-5's 20-10-10) and already has a ~20uF bypass on V1a, so I tried drawing the remaining changes (in purple) on the layout of my slightly modded 5F2a. So that's what? swap out 7 resistors, plus clip out the 1M and the jumper from input 2 switch to 1 tip? Questions: Would the tone control still work? work the same? Is there a downside of leaving the Princeton's full 32uF reservoir instead of 20? What am I overlooking?
