Have any VAC owners tried any KT-88's


other than VAC's? If so can you share your experiences?

In my PA100 I prefer the "Winged C" tubes. When I had the Phi 110, I preferred the VAC tubes.
The "Winged C" is a 6550 which may not meet the KT88 requiremnets. Only the earliest 6550 could replace KT88. The VAC tubes were Chinese.
YES- Svetlana(AKA Winged 'C'/SED St Petersburg)) has been making KT88s since(AT LEAST) 1999. I was using their EL34s in my ST-70, over 16 years ago.
