Thanks - will chase down the ECC82s. Cause I can’t get these adapters out…The ECC83 (European name for 12AX7) has gain of 100x. It is too 'hot' for LP. The stock tube, 6922, has gain of 32x. The ECC82 (or 12AU7) has gain of 20x. That is why I use ECC82s in LP: also, the slightly lower gain creates signal 'headroom' for the LP circuitry. Plus, more clockwise volume knob rotation is possible. EDIT: you can use those Pulse Tube Store adapters with ECC82s.
