Blown PT in 69 Superlead need recommedations

Post by redozzman » Mon Jul 19, 2021 2:39 pm

Not sure how many folks are reading this forum these days. Regardless, My PT went out on my 69 Superlead, and about to buy a replica, I'm looking for recommendations, Heyboer has several models, also, is there any specific areas on the board that I should be looking at replacing or reviewing that could have been compromised when the PT went out. The fuses didn't blow, the amp went silent. Its definitely the pt, it was very hot and smelled burnt, also had some ooze coming out of the bell housing holes.

Thanks in advance for any advice.

Heyboer makes a PT to Metroamp specs which you can find in the Metroamp store. Marstran is also a great supplier that sells Heyboer transformer wound to his specs. You could also save a few dollars and purchase a standard Heyboer PT from "Amp parts Direct" There isn't any mojo in a PT and as long as it delivers the correct voltages, I wouldn't have any problem using the less expensive option. Hammond is another option that makes some great iron.

I would check you power tubes and filter caps before replacing the PT. It's odd for a PT to simply fry itself and it's very likely that one of these items was drawing excessive current. ... by-heyboer

You could send it to Mercury Magnetics and have it cloned, or rebuilt. I've had that done before. Talk to Patrick, tell him Scumback 1 sent you and see if they still offer that service.
