I have the following transformers:
Stancor 52C046
Chicago Transformer TR-1040
I don't know what the secondary ratiings are. A Google search turned up zilch. Anyone have any info on these?
I did an open circuit voltage test and found both of the secondaries put out ~5KV. The thing the bothers me is one of them says the secondary should be in the 'hood of 2.5KV. I'm not sure what the secondary is supposed be on the other.
A quick Google search turned up this mail message from 1999. The 52C046 is a Hallicrafters part number used in the BC-610. See second paragraph below:
"Mon, 15 Nov 1999 07:13:21 -0600
Iin the bill of materials for the SCR-399 by Hallicrafters, the modulation transformer is listed as: Transformer, modulation; prim. 16,000 ohms c.t. ; sec.8330 ohms c.t.@250 ma. source is Stancor; Signal Corps part no. 2Z9634.3 Hallicrafters part no. 55C028.
Plate transformer: Transformer, power; prim. 117v tapped to provide 4000 or 5000 V.C.T. @ 500 ma. mfr. Stancor; Signal Corps prt no,2Z9612.1, Hallicrafters part no. 52C046: Another H.V. transformer for the 450 v supply is listed"
And another from 1998:
"bill of materials for the SCR-399, of which the BC-610E is the basic tx. FWIW this is it---Plate tx. Stancor mfg. 117v pri. 5 or 4 kv ct sec at 500 ma. sig corps p/n 2Z9612.1 Hallicrafters p/n 52C046. the matching choke is: Stancor mfg. Hallicrafters p/n 56C062"
