Croft specs - too much gain?

[Wegamus]

I believe it will and yes the gain is too high.

Oh great, sounds like we’ve identified the cause and solution of the problem. If I were to have the preamp mod you mention, would I also be able to comfortably use a Quad 3O3 with the preamp too? I note that both the 7R and 3O3 have 0.5V sensitivity but I don’t know if any other factors are relevant.

I’ve had the 12BH7A valve fitted to the power amp input for a few days now and it’s a lot better in terms of hiss and there’s a bit more range on the volume control too. Still not as quiet as my NAD integrated but quiet enough to not really matter anymore.
