Manufactured:Japan, 1977-197x (Discontinued)
Main PCB: USA
PTBM051AOX by Cybernet Electronics Corporation

Sweden
PTLD?????? - LED display board
PTSW075AOX - Channel selector board
Additional info: The swedish version still had a 40 channel selector but was modified
with an extra board that disabled all channels above 22 and used the
ch 23 position as 11A. A weird solution, but it was required to comply
with swedish law at the time.
