[Amps] Amp Supply LK800 XFMR question

[Carl]

The 800A runs 2200V key down. The original TNY uses the LK-550 xfmr @ 
around 2500V and later Dahl provided one with a Hi-Low tap. Ive had 
several of all versions thru here for repairs, upgrades and 6M 
conversions. I was also an authorized service shop while Amp Supply was 
still in business. Denny Had also built small runs at Cary when he had 
enough advance orders/cash. He may still sneak a few out.

All 800 xfmrs were made by Dahl that I know of.
