I snagged this super-fine SVT today by making a four hour (round trip) drive to Tucson.
After getting it home, I only had a short time to revel in its sonic riotousness before a
mothers day gathering cut my brief bliss short....but It sounded simply amazing!
I found it on craigslist for $800, Its really clean and nearly scratch/roadrash free.
The seller claimed to have bought it new in 93, and only had it out of the studio for a
couple shows. He also claimed it still had all the original tubes, but after inspecting the
6550(s), I found it has a mismatched set of 4 GE and two (made in USA)-Groove Tubes.
(Besides the labeling), all 6 power tubes look identical, inside and out...
Was Ampeg using General Electric and G/T tubes around early 93?
And could Groove Tubes have been relabeling General Electric brand tubes in this era?
I think I'll take it in for a check up just to make sure every-thing's well, but it played
very loud, sounds fantastic and was nice and quiet at idle (with the volume at up high),
so I'm one very happy camper...
The serial # seems to be dating this amp as a January of 93 manufacturer. Is this correct?
(5th digit-F / 6th digit-1)
Thanks.....
