Hello-
I have several sets of audio transformers for sale, from the Collins MD-141
modulator. This modulator used a pair of 4-65A's in P-P to modulate a pair of
4X150 type tubes in the companion VHF transmitter. I believe there are around 5
transformers total in each set, plus an input filter. The audio strip used a
pair of 12AU7's, followed by a pair of 12AX7's and on to a pair of 6AQ5's.The
modulation transformer is made by Chicago Transformer, part # CSTC 18075. It is
Collins part # 677 0529 00. It is marked 1425 WV, 200 - 15,000 CPS, Primary P-P
plates, has 3 secondaries one being 2400 ohms @ 350 MA.
I will try and get as many of the key parts {associated with the
transformers} as possible, such as 4-65 tube sockets, etc. I would like 75.00
per set plus shipping. Thanks, Byron WA5THJ.

My landlord in the 70's claimed that my 80 meter dipole was the cause of
his burnt toast every morning. It brought "electrical waves into the
building" It was only after his enlightened son interceded on my behalf
that he purchased a new toaster.
