We do not have the proper reference materials to be able to determine which power transformer will work with your amp. The best thing to do is take your amp to a qualified tech to determine the proper replacement.

The transformer in the Vaporizer schematic has the same secondaries but lists a different part number. Compatibility with the Vaporizer circuit and mounting dimensions is unknown.
