Kan en bruke kt77 i cs-100a?Kan se ut som det er en ikke er helt ukjent problemstilling med KT77?
Tube Bias VDC EL-34 vs. KT-77 and KT-88
Assuming DC voltage setting for bias is .30 to .35 for EL-34, what should the setting be for the KT-77 and KT-88 ? My thoughts(uneducated), is the...forums.stevehoffman.tv
" Without knowing the amp or the plate voltage, you can safely assume that a PP design (as most amps using these tubes fall within a known range here) that they expect to see for EL34 = 30 - 35 ma, KT77 = 35 - 40 ma, and KT88 = 35 - 45 ma. Some amps can have them set even a bit higher."
"Since we are discussing, is it feasible that my newer Golden Lion KT-77's barely meet the low end of the EL-34 suggested bias setting for the amp, and have no adjustment left ? While the stock EL-34 easily hit the suggested range with plenty of pot adjustment left."

De var vertfall ikke på lista i cs-88a
