Found this huge toroid for ~20 bucks on Tradera (Ebay, sort of):
800VA with 230 + 33 + 2x11,7v secondaries. Current rating of each winding is unknown but judging by the wire gauge it should be more than enough for output stage B+ and heaters. 300VDC is a bit on the high side for my application but with >60V dropped across the cathode resistors it might turn out just right. With this beast in the power supply and the 120W-rated 1650T output transformers it would really be a shame not to use 4 x PL519 per channel and get 50-60W class A...! |
