Gibson made a few iterations of their venerable 30 watt stereo amp. They made it with reverb, without reverb, with and without tremolo and had a few different nameplates as well: Gibson, Maestro and Bell. They were all pretty much the same amp with different features. The early tweeds had Jensen P10Qs but very quickly changed over to C10Qs. This one is a GA-78 which means no reverb but it has tremolo. It is badged Bell but is, of course, the same as the Gibson and the Maestro. Filter caps are done but everything else looks untouched. The speakers are C10Q's dated from 65 so we know they aren't original. Three prong AC added. Original footswitch is still hardwired to the chassis. This is the amp that was made to go with the Gibson stereo guitars of the era-ES-345 and ES-355. There is a dedicated stereo input for these guitars. There are also inputs for your phonograph and standard guitars as well.
This amp is 18 watts per channel and can be bridged to mono which is supposed to put out 30 watts but I think that's optimistic. Great sounding-very musical amp. Good headroom especially for the era.
