Title: PT-12 power transformer

Doc,Paul,

Made a Moreplay purchase and have looked at the manual, very simple elegant circuit. My question is (if I am allowed to know) how much heater current can your propriety PT-12 safely supply? Inquiring minds need to know, as the gears have already started to turn.

It was designed to handle a maximum of 2.5 amps RMS.

Be aware that the internal resistance is unusually high, in order to keep the magnetic flux low.

Paul,

Thank you for imparting that info to me (US). That's about what I had expected. There is of course more than one way to skin a cat. Again thanks.
