Default Re: KT66 as substitute for KT61

Thanks to Nigel, Jeffrey, and Tim for help. I must admit I never thought about using an EL33. I had a KT66 to hand, thats' why I checked that out. 40mA seems about right, so if I go with the 66 I will change the Cathode bias resistor. Will also check out< www.r-type.org/exhib/aaa0466.htm >
