The only real heavy metal here is this BC-610. Had a few GPT-750's and many SBT-14's, but a man can only maintain (or lift) so much of this stuff.
This is a "I" model, serial number 8, contract number 3164-PHILA-51-01-C, manufactured by Hallicrafters. While a full set of tuning units and tank coils are available, the 610 usually sits on 3885 for AM work. Audio is provided by a 614 speech amplifier - same order number as the transmitter, but serial number 17. The 610 was re-tubed, as most tubes were missing except for the 2A3's (!). In my case, this was relatively painless as I had obtained a box of 250TH's and 100TH's at a fest for 10 bucks a few years earlier. The junque box suppled remaining tubes. Note the tuning charts in the pocket on the right side of the transmitter. You can also see a BC-939-B tuning unit perching on the top of the 610.
Once saw a fellow shelling out the cash for a BC-939 at a hamfest. He was large, with a beard to match. Walked up to him and said "Got a 610, eh?". His reply - "I've got 4 of them".
Fun to operate, the BC-610 is a must for all BA Shacks.
P.S. The keyboard if the foreground belongs to a ASR-35. Anybody want one?
