1958 Gibson GA-6 schematic (2nd version with two 12ax7's pre-Lancer)

[Redbird]

Just bought a 1958 ga-6 last week and it had the original instruction booklet with the schematic. This schematic seems to be rare because I haven't found it on any sites for Gibson amps. It's the missing link between the first version and the Lancer. Hope it helps and prevents people from modifying a great amp!

Here is the schematic I put on online:
