This was one of those 2-day projects that took 3 weeks because I kept putting it off. I had 2 of these old 9-watt Gibson GA-9 amps and decided to do a little work on the one. I also got a little jeleous of all these guys building kit amps so I decided to rebuild the entire electrical system. The only things I didn't replace were the 2 transformers. I've read these amps use the same circuit as one of the Fender Champs but I'm not sure which one. The difference is that these old GA models from the 1950's go for about $150 on Ebay. I also like the fact that you can run it completely cranked and it stays clean with the old RCA metal pre-amp tubes. I've found the glass Sylvania's will break it up if wanted. This one has the factory 10" speaker and runs a 5Y3(rect), two 6V6GT's, and a 6SJ7 preamp tube. Even with the two 6V6's I can crank-it and you can barely hear it outside my appartment. I checked with my wireless. I added my old Cavalry unit's colors as a personal touch, as well as the purple jewel. The Boa pattern tolex was ordered through Vibroworld at around $22(?) yard. It took just over a half-yard for this amp. I figure I've got just over $200 into this one. If(or when) a transformer finally goes I'll be out another $40. Still, it's a point-to-point with a solid wood cabinet and all-tube circuitry. I encourage anyone who has ever thought about this sort of project to give it a try. It's a great feeling when you plug it in and it still works. Thanks for the look.
