[sdiy] OT Tape play heads

[frey at radioles.com]

Apologies for this double post. I missed the list in my original return.
Quincas et al, I found a pcb layout for a NAB amplifier. That is the part I am most happy with. Next round will be with an erase head I suppose if it is mono.

There are examples from these live performances. 38-Barbies is our name so the tape loop is “38-Barbies” and “You know, I don’t know”. Generally at the beginning and end of performances.
