[QUOTE="Ampdog, post: 989939, member: 144"] HH NS1000, I may be repeating: did not reread the entire thread. The difference between 6L6GC (5881) and KT66 is smaller that the spread in characteristics of either. Replicas in appearance may be more attractive. but are also often significantly more expensive. I have long since stopped bothering about this and am using 6L6GCs for years now. Your money; your taste. (As stated earlier 5881s are also suitable - just; this regarding anode dissipation. bit I have found some 5881s to be more expensive than 6L6GCs!) (Further repetition: Many Russian KT66s are using the exact same innards fir KT66 and 6L6.) Also bringing forward other perhaps misconceptions: The use of more powerful valves: The output power of an amplifier - all else being the same - depends on the voltages/currents available. It is utter nonsense to replace KT66 with EL34 or even more ridiculous, with KT88s, and only taxing the power transformers more. (What will 'they' do next - try KT120s?) [/QUOTE]
