Newmarket miniature audio amplifier AC2
I wonder if anyone has drawn up a schematic for this little amplifier board.

Re: Newmarket miniature audio amplifier AC2
Do you mean PC2.
If so, there's some useful info here: https://www.vintage-radio.net/forum/...ad.php?t=66460 The Wylie guy was very helpful back in 2011, too.

Re: Newmarket miniature audio amplifier AC2
Hi,
If it helps I've scanned and attached the data sheet for the PC.4. It has the circuit but no values, however looking at the previous post the values of the PC2 are on the diagram NKT_PC2.JPG I've the PC.3, PC.4 and S13 in the modules box. Looking at these it appears to use the same basic PCB and circuit and each one changed to give different gain, input and output sensitivities and impedances etc. Edit..... was a Newmarket module used in the Discatron or am I barking up the wrong tree, which I suspect I am!
