Stock tubes are EH EL34 (russian tubes) but we have customers who upgrade to Treasure 6CA7-Z for $249 per quad with very satisfying results.
robert h. levi in his review for positive feedback stated:
"Pull the EH 6922s and replace them with Tungstram PCC88s at about $45 each and replace the Phillips 5687 with a Tung-sol 5687 at about $40. Just three little tubes per unit to live the dream! They are available at Upscale Audio and VTV. No other changes needed. By the way, turn the amps off for this tube change! The EH 6CA7s are quite good and about as musical as current production allows."
a former distributor for the amp said the pc88 would not work in the 800's.
my question is will they work in the cyber 800?

KT88 tubes cannot be drop in replacing EL34 in Cyber 800. The amp has to be modified in order to run KT88 tubes.
not kt88, pc88/7dj8 as a replacement for the 6922's.
