Russ Payton Posted October 19, 2008 Share Posted October 19, 2008 Is there anyone out there with good information on where to get repair parts for my GA-20T? I am looking for exterior parts at this time. ie: fabric, grill cloth and so on. I've looked on line without much success. Thanks Russ Quote Link to comment Share on other sites More sharing options...

bluesdaddy57 Posted October 19, 2008 Share Posted October 19, 2008 don't no where to get parts but i do own a 1957 ga20t.still has the original 12 inch jenson and wood trem foot switch.it was found in and attic and it looks as if it was drug behind the veh rather than puting it in.there is a local tube amp guru who put it back in playing condition for me.i know he found some tubes on the internet.this amp looks like #@!#*^#@! but man when it's fired up.i use a jump wire between both channels and roll both voulmns to about 8 plug in my 67 sg with p90s. it sound like a voice from heaven Quote Link to comment Share on other sites More sharing options...

jhguitarlab Posted January 18, 2009 Share Posted January 18, 2009 Russ, or Bluesdaddy, I own a 59 and I'm currently trying to wire in the Trem footswitch. Someone removed it and rewired the circuit "on". Any chance you might have a pic where those wires connect at the control pots? Thanks - love these amps!

Mike Mack Posted October 19, 2019 Share Posted October 19, 2019 I just bought aN all original 57 GA20T from a store in NYC, and am having it shipped to Australia. It’s my first vintage Gibson. What sort of sounds can I expect to coax from it? All my other amps are 50’s Fenders. Quote Link to comment Share on other sites More sharing options...
