Microdrive r/w head wanted

[roganjosh]

Does anyone have a working R/W head for a Spectrum microdrive for sale? Either a discrete part or one cannibalised from a unit with some other fault. A simple check for head functionality is that the 6 pins consist of two pairs with a resistance of approximately 15 ohm and one pair with a resistance of approximately 90 ohm.

I have a couple of bare PCB assemblies from old Microdrives. I’ll dig them out and test them.

Much appreciated.

Both heads are giving me 13 & 90 ohms so the heads seem okay. I think the ULA’s were the problems with these.

Thanks very much for that. The heads sound fine and I'm certainly interested if you'd be willing to part with one or more. I'll PM you.
