Can i use KT88 tubes directly on My ST70 Which i have made recently
with Original PC3 driver board and 7199 tubes, EDCOR CXPP60-8-4.2K OPTs.
I am using custom made EI core Power Transformer ratings with
360-0-55-360 @ 500mA
6.3v @ 5Amps (heaters)
5v @ 4Amps (rectifier heaters)
Rectifier tube i am using GZ34 with my own custom made power supply board.
But i did not changed any component values in the circuit.
Can you please advise me is it possible KT88 to use in this condition?
If it is possible what changes need to be done before use the KT88.
right now i am using RCA 6ca7/EL34 NOS tubes
