Cinemag B11178 Input Transformer for all UREI UA LA-3A, 2-LA-2 (L Bracket). C17
New Replacement “T1” B11178 input transformer for all UREI and UA LA-3A’s, and the UA 2-LA-2. This matches the Cinemag B11178B transformer that UA uses in their reissue LA-3A and 2-LA-2 except that this version, without the B suffix, mounts with an L bracket instead of threaded studs. Electrically this is the same part as the original B11178, which was made by Cinemag for UREI back in the 1970's. A datasheet and wiring instructions are included with this item.
This is a bridging input transformer with dual primary windings and a single secondary winding. It can be strapped for 1:5 ratio (as in the LA-3A) or 1:10 ratio. In the 1:5 LA-3A circuit the two primary windings are wired in series and the transformer has 12 db of gain when properly loaded. For other applications the two primary windings can be wired in parallel, giving 18 db of gain at the secondary. The transformer has a case shield and electrostatic shield, and is well shielded against hum and RFI.
It can also be used as a mic input transformer.
