>>What a bummer I had hoped to go back to NOS one day!<<NOS 7868s are SCARCE and becoming SCARCER, with every passing day. Be VERY grateful New Sensor put the type back into production.
IMO, the pin size issue is minor. Without the new production, many nice units could end up being "parted out".
Check the Sherwood schematic. If the amp uses "fixed" bias and the 7868 grid leak resistors are <= 300 KOhms, you are good to go.
The grid leak resistor value limit is higher for cathode biased amps.
