The four KT88s in my Chinese valve amp are cheap as chips 'no brands'. ThoughtI might try some replacements. Seems the Electro Harmonix tubes are well regarded and reasonably priced.
Should I try replacing my KT88s with EH KT90s? They are apparently a drop in replacement for KT88s.I read somewhere that KT90sare more powerful - does this equate to more wpc, or is it not as straightforward as that?
Grateful for your opinions.
As a tube-rolling newcomer, how much of an improvement/change should I expect from new/different output tubes and would a greater improvement come from new signal valves?
It's all Greek to me....
