5751's all the way for me, and thanks to MikeC, I have a few to tide me over. Not sure if you'll see much difference in headroom tbh, for that I'd have thought you'd need to venture into the 12at, 12au or 12ay realm. I'm sure I have some kicking around if you wanted to try.
Thanks for the offer, but I think I'll likely play around with the NFB resistor if this doesn't have enough of a desired effect :thumbup:

Hey JB, which is the NFB resistor on the AC10C1?

It’s on the Laney cub 8 that I want to change it :-)

Going back to 5751’s, they’re a magic tube in the right position. I’ve cooled down many a hot headed amp with these, and not just in preamp - phase inverters also.

So apparently the Monoprice 5W is the same amp under a different name, its all surface mount bullshit but I have seen people who have added a NFB pot wired to the pads where the NFB resistor is... R13 I believe on the schematic.

Likewise, R8 appears to ensure there is always a load on the OT.

Oh yes maybe R8, I have vague recollections of it being 220 something something ohms :rofl:
