Just wondering if anyone might be able to supply some better quality versions of the attached images. I'm looking for either a very close match or ideally exact copies. Don't need to be particularly high res.

The amp is a Mullard design, possibly EF86+EL84+EZ80 but those valve numbers could be wrong.

TTFN,
Jon

Hi Jon

The amp looks like a MUllard 3-3
It's here :

Hi Jon,
I think this is "another" variant of the Mullard 3-3 which seems to crop up in slightly different versions (e.g. differences in feed to EF86 G2)

There's something very similar here, but again with what appear to be some different resistor values compared to your circuit:

Another version for comparison:

Cheers chaps, yes, that's the amplifier, thanks ! One down three to go ... well 2.5 to go as half of the second image is on Steve Ostler's excellent website.

TTFN,
Jon
