Recommendation for R-core transformers

I am looking to purchase 2 R-Core transformers with 50VA power ratings. They need to be custom wound for dual 115V primaries (able to be wound in parallel) and dual secondaries (one(150V, 0.1A) and one (12V, 2A)). Can you guys recommend a good company to manufactre these R-cores for me. I bought some that were these specs from the DIY-Gene gy, but one put out so much power it blew the LEDs and fried some resistors opn my HV shunt board. Also, the 2nd transformer overheated and melted the plastic covering the wires. I don't recommend these R-cores. Anyway, if you guys have suggestions I am all ears (eyes). Thanks guys.

"I'm yet to hear a Polk speaker that merits more than a sentence and 60 seconds discussion."

My response is: If you need 60 seconds to respond in one sentence, you probably should't be evaluating Polk speakers.....

Greg, Now I'm no expert but I don't think it's the transformers, if you frying resistors and popping leds I would re-check the schematic to be sure your wiring things right. Also you might want to put that a-side for a bit and go do something else (hint, hint
) to clear your head and come back to it later. It works for me. Just a thought “The two most important days in your life are the day you are born and the day you find out why.” ~ Mark Twain
