Re: Quad II owners

I also use QUAD II amps and prefer the GEC KT66 valves, of course :)
To answer your question...I have tried both the Chinese and Russian KT66 valves in the QUAD amp...
I have found the Russian KT66 to work out the best... The Chinese KT66 valves lacked the "air" and openess on the top end...
The strength of the tube is critical as well...
I found that the Russian KT66-HP from Groove Tubes in a number# 8 ratting to be the best sounding, consistantly..
The #10 ratting had loss of highs...this is due to the early voltage getting smaller and the plate resistance reduction...
