NeonDinosaur Posted February 12, 2011 Author Share Posted February 12, 2011 Thanks for the response, but more so for the enthusiasm! The nameplate reads "Gibson Electronics Kalamazoo Michigan" on one side, and "Recording" in big bold letters on the other. There are 6 tubes: Peta Laboratories - 6L6GC (and then 9141 going down the side) No Name - 6LG WGB No Name - 6FQ74/6CG7 No Name - 6C4 Sylvania- 6EU7 (x2) There are 2 channels and 2 inputs for each channel. Each channel has a volume bass and treble pot. There is also a 1/4" jack that says monitor. Finally a 4 way selector switch but i can't read what it does. Thanks for all the help if you need any more info I'll be glad to find out. Link to comment Share on other sites More sharing options...
Grog Posted February 12, 2011 Share Posted February 12, 2011 It's a GA-75 Recording. It came with either (2) 10" speakers or (1) 15" JBL. It's actually a fairly rare amp. Only 181 GA-75's were produced with the ten inch speakers, and only 74 GA-75L's were produced with the 15" JBL. This is a scan of the 1966 Gibson Catalog.

retrorod Posted February 13, 2011 Share Posted February 13, 2011 There ya go NeonD...Great help Grog! Now which is yours...2X10 or 1X15? Link to comment Share on other sites More sharing options...
NeonDinosaur Posted February 13, 2011 Author Share Posted February 13, 2011 Thanks for all the help guys, it is appreciated. The amp that I have is the 2x10. The speakers in it look pretty new (and they say "Fender" on them) so i'm sure they are not original. They are 8 ohm, 30 watt Model V 1030 speakers. Do you guys know if these are good replacements, or should I find a different model to more represent the original sound? It looks like the previous owner tried to add a ground by splicing in a three prong plug. I'm not opposed to this as it is much safer, but they didn't do a very good job so I was gonna redo that, and get some new plastic for the handle as well as a new logo for the front. Electronically everything seems to be in working order I can plug in and it sounds great! Thanks again for all the help. Link to comment Share on other sites More sharing options...
Grog Posted February 13, 2011 Share Posted February 13, 2011 The original speakers should have been either CTS squarebacks or CTS speakers with round magnets, depending on if it's an early (squareback) or later in the run. Link to comment Share on other sites More sharing options...
NeonDinosaur Posted February 15, 2011 Author Share Posted February 15, 2011 Thanks rod and grog for all the helpful replies. Its nice to finally know exactly what amp this is. One last question, I understand that the amp is rare, but I feel there is a big distinction between rare and desirable. Just out of curiosity, is there any way to tell how much this guy is worth?

Thanks again for all the help. what are the manufacture codes on the speakers (if you have them)? it could be they may not be origional, but correct.
