Hi Dave yes I have one, but just the mixer not the tapered adapters (hint hint!) I am behind you as I have not got an application for mine. I bought it on UK...

Hello, I'm looking for a manual for the HP 312A Wave Analyzer. BAMA has one for the 312B/D, but I'd like one for the 'A' model. Does anyone have one...

In fact, it might be worth putting a piece of soft iron across the gap in the poles to reduce the field in the air gap while you go fishing. Also, I might have...
