Another discovery on my "mystery" Alpha 76A. It is suspected by one or more
of the brain trust here, that the transformer was possibly taken from Alpha
Industrial inventory, MRI related units. The transformer is open frame, with
no "bells" but transformer paper and tape, covering the outside of the
windings, and the power leads in/out entering top and bottom, both sides.
Clues: I have not weighed it, but in moving from old QTH to new QTH by car, it
was REALLY heavy. Opening the cabinet shows the old style stacked laminations
7.5" wide, 6.25 high, and 3-1/2" thick. The other clue is near zero clearance,
left edge of xfmr core with the control board. Looks like only one set of
holes, (same ones used) studs for transformer chassis mount. It looks like it
overfills (very tight clearances) the designed space for the transformer for
the amp. The Core stack is Stamped BTC 11163 and appears to have date stamps
83 35, Any ideas on the nature of this particular transformer?
