I am building a pair of KT88/6550 50-60 w mono amps and was curious what others have used for a similar setup in terms of output impedance. I am torn between 3.4K and 4.5K options. How much power lose if I go with the 4.5K vs. the 3.4K? I want to buy good iron and I will not be able to does this twice in the near term :-)

- That is what I said: Favour the OPT - meaning smaller turn ratio (nt) - KIS 17:25:15 01/25/07 (1)
