Hello Group !
I picked up a nice lot of audio trannys recently and have found nothing on them.
The mfg? is Transcore with one of them a Silicore.
These appear to be circa late 50's 60's and possibly for solid state circuits.
TS-D 126 C9 - 500, 5.5, 11 ct Ohms 7 connections total
TS-D 127 C9 - 500 Ohms, E1(-) E2, C1(+) C2 () = ct 8 Connections total
TS-U50 L2 - 200, 5, PM (ct), 5 Ohms (Silicore)
TS-Y 93 E9 - 200 Ohms, E -, C + 6 connections total
The shels are made of square corner, spot welded panels with the terminals on a brown phenolic plate inside a round cutout of the bottom metal plate. They look very similiar to the Langevin Maxson types.
Mounting is by recessed pressed in nuts.
The 93s are clearly input, 127 output, and the other two probably line to speaker.
There are 4 of the 93s and they look unused.
It has been too cold for me to get out to the workshop and run tests so thought maybe someone
here has seen this Mfg before. Could possibly of Euro origin as some Telefunken trannys were also in the lot.
Can get some pix and test results once I can heat up the place.
TIA,
Bill
