Default Re: Tape Head Open Circuit

Hi Paul,
Just looked at my machine (no name on it as far as I can see) and had a look at the playback head. I'd say it's a little smaller than a typical "sugar cube" head from that era. With that in mind I've taken a couple of heads from their mounting plates - one seems to be a typical sugar cube, the other a little smaller from a front view but slightly deeper. These two seem to have less wear than other similar ones in my collection.
I measured their resistance using a DMM and a 10k series resistor and they both come out around 400 Ohms. They're certainly valve era heads so worth a try I reckon. Maybe you can hold them up against the passing tape before spending time properly mounting them.
PM me your postal address and I'll get them in the post in the next couple of days.
Graham
