Following on from Andy's thoughts to modify the output stage from SE to diff. The EQ feeds this stage. Currently it's LL1544a-EQ-5687-parafeed LL5676. The EQ is regular all in one CR but fed from the 1544. This is real easy to change to a diff cct similar to Dave's and the thing Andy built. I'll try it first with iron in the anodes coz I got it and don't have the FETs. I can then compare the differences later.

However my question is, does the series R to the EQ, which will now appear in both input legs stay the same in both legs or half the original into both legs?

thanks,

Stephen
