For sale is a single Vintage Stancor HF-68 Push Pull Parallel to Voice Coil / speaker output transformer for Tube Amplifier as seen in the Pictures! Pictures are of the actual transformers you will receive! Stancor HF-68 is exactly identical to UTC LS-58 and Stancor seems to have contracted a limited production for their line HF and WF series with UTC at one time. The spec of the HF-68 and LS-58 is exactly identical and HF-68 is potted in the same type of sand cast Aluminum case with a bit different in appearance. HF-68 is for use in Push Pull Parallel circuits with 2A3 / 45 / VT52 tubes according to the Stancor Catalog. This is a fairly big transformer with almost 40W power rating and weights over 16lbs. All Coils Are Tested with a Signal Generator using sine wave from 20-20KHz and an oscilloscope. This transformer is physically and cosmetically in very good condition! I will include a printout of the UTC Terminal Hookup (Pin out) with them since it is the identical to the LS-58.
