1965 Gibson Recording Model GA-75L Amplifier


Recommended Posts

Hello forum members!


I'm needing some help determining the value of this excellent condition 1965 Gibson Recording Model GA-75L Amplifier I acquired recently. It's easily one of the best sounding amps I've ever heard/played through. It's got a sweet yet punchy overdrive with a huge bottom thanks to the 15" speaker. It's also considerably quiet for a vintage tube amp. I can see why they used these for recording. The iron in this thing is massive. Think 5150 sized transformers plus a choke. You'll notice in the pics that the factory 15" JBL D130F has been replaced with a import 15" Jensen Neo (a sin I know but it sounds decent). I still have the original JBL D130F but it needs to be reconed, I plan to have it re-coned in the near future, as well as installing a fresh set of NOS RCA black plate 6L6s. It currently has a set of JJ power tubes. All preamp tubes are NOS RCA except for the 6FQ7 which is a NOS EI. I'll replace it also with a NOS RCA since they are pretty easy to find. The amp has already been serviced with all electrolytic caps being replaced with Sprague and F&T caps and a new 3 prong cord installed. It came with a original vinyl cover that is in fair shape and the original instruction manual w/schematic which I thought was pretty darn cool. I have no idea what the value on this amp is. There is not much info available on the web. At least not much that I can find. Anybody know where is the best place to get the JBL D130F reconed? I'm considering sending it to Weber. Any help or information would be great. Now for a little eye candy for all you vintage Gibby lovers.

Probably the best way to find info on these would either watch eBay and see what they say about theirs and how much they go for. I would think weber would be a good place to start with the reconing of the JBL. You might join the telecaster forum TDPRI and upload pics and ask. They seem to be a lot more knowledgeable on Gibson amps then here. I asked some similar questions about and old Gibson amp I recently bought and got 1 short reply back so I wouldn't expect to much help here even tho it is a Gibson forum.

The 2013 VG Price Guide is just coming out, all I have as of now is the 2012. It list it at $525 to $650. It's the same for both versions, (2) 10" speakers or the 15" JBL. In my opinion, the 15" JBL should be worth more.

I usually use this guide & what things actually sell for on eBay etc.....to price something. This amp is so rare that youy likely won't find any to compare it to.
