I agree. And those 10k grid stoppers (preferably metal film or metal oxide) should be soldered directly to V1 pins 2 and 7 to minimize the chance of radio station interference getting into this very high-gain amp. Likewise, you would need to take great care with the layout and "lead dress", using shielded wire for longer signal connections, as well as "modern grounding"JMPGuitars wrote: ↑Sat 10/09/21 12:35 pmHowever, I would probably also use 10K grid stopper resistors on both halves of V1.
