[Kenwood] IF-10B digital unit questions

[Roger Shultz]

Thanks Pete, that appears to be the case and I'm told that East Coast
Transistor still has stock. As it turns out I have the instruction manual
but never looked closely enough o see the part number nor to check to see if
it was available. I was lead to believe that it was "unobtainium" so I hope
it works out.

According to the IF-10A/10B service manual, the EPROM is MBM2732A-30.
