The 291YX is a replacement power transformer for the Yorkville Sound/Traynor* Bassmaster, listed for the YBA-1 and YBA-1A. It is intended for technicians and owners restoring these tube bass amplifiers who need a transformer that cross-references directly to the original.

The 291YX has a domestic 120V, 60 Hz primary and is built on a bobbin core. It was physically designed to look similar to the original factory unit where possible, with materials and design specifications kept as close as possible to the original part to preserve the stock tone.
