The battery feeds through an input transformer (LL1676), so no need for a coupling cap. See schematic. The battery is bypassed with a 10nF Multicap - the other cap and resistor shown are an RC network across the transformer secondary to snub any ringing. Made a big difference in clarity versus cap-coupled, which I tried first.

- If it wasn't so difficult (and expensive), I'd design every stage for A2 and be done with it" Hear here~nT - Cleantimestream 08:41:44 07/28/14 (0)
