I've not had much direct experience but am aware that the ECC85 wasn't the best ever valve. Its intended application was in FM radios where it needed to be in top condition to give decent reception. I think some people have replaced it with ECC88, a better valve, widely used in Tektronix 'scopes and other professional kit. Unfortuantely popular with audiophools.
