According to the RCA tube Receiving Manual, the ECC88 has a peak plate voltage of +130v. So why in the Gyraf SRPP amp is it fed +250v? I imagine it can probably handle it, but why run it so hot.
Also, why is the heater voltage rectified? An ECC83 can handle 6.3v AC or DC.
I know some times this stuff is done for a reason, but other times it just is. If it isn't crucial, I'll just use a Hammond 269AX.
