I'm looking for a readable schematic for this dog! I found the regular 45rvt, and a really bad copy of the 45rvt Saturn but I can't see it well enough to tell if there are any differences, and Gibson was notorious I understand, for being a little loose with the documentation.
Anybody have anything on this?
Thanks!

Pete

Thanks Bill, I saw that one too. The schematic is the same GA-45RVT that I found. I guess there isn't that many differences. All I'm doing is a recap, and de-butchering the last guys efforts for a good friend of mine.
You don't see too many guitar amps with dual "firecracker" style filter capacitors, but that's what this one has which is consistent with other pictures I've seen. That young mans chassis picture in that file shows a can, chassis mounted cap which is the only picture I've seen with that in there. I've heard Gibson wasn't much on keeping up with engineering changes, and this amp proves it!
Thanks again,


Pete

He installed the two can electrolytics right? Something about punching holes. The pictures weren't clear enough for me to see wiring.
