|Sean Kilback||Gibson Discoverer GA-8T thoughts|
I just picked up a '64 (I think) Gibson Discoverer Tremolo GA-8T for $40 Canadian. I was told it "doesn't work" but the recitifier and fuse are missing so I'm not suprised! Tube compliment is 2x 6EU7, 2x 6BQ5 and a 6CA4 rectifier (according to the tube chart). It's got a 1964 CTS alnico speaker.
Two cool features: "Monitor" output...presumably a line out, and "Echo speaker"...presumably an ext speaker jack.
1. General opinions on this amp?
2. Known problems or limitations?
3. The schematic for the GA-18T in Weber's book seems to match the tubes/features. Is there an accurate GA-8T schem somewhere?
4. Any Discoverer Tremolo owners want to swap stories?
5. Good deal?
Can't wait to replace the rectifier and fire this baby up! I'll do so without the other tubes first, then go from there. If it sounds promising I'll proceed with a cap job and maybe upgrade the speaker.
Thanks very much!
