I was just browsing Triode Electronics and came across these OPTs for $39.95, I wondered if anyone had any knowledge of them or is brave enough to try a pair. They're at

Here's the description:
A generic 100W output transformer for use with 4 6L6-GC, EL34, 6550 or KT88 tubes. 1800 ohm primary with 4, 8 and 16 ohm taps. DC resistance across whole primary is 60 ohms.
4 1/8 inches (105mm) high X 3 3/8 inches (85mm) wide X 3 3/4 inches (95 mm) deep over the end bells, weighs about 9 pounds. Mounting centers are 2 5/8 inches (65mm) by 2 5/8 inces (65mm). Judging from the size should be good down to 40 Hz at 100W, about 75W @ 30 Hz, and about 45W @ 20 Hz.
Yes, these transformers are a bit cosmetically challenged, (some rust on the lams) , but for only $39.95 it's still a heck of a deal for a 100W output transformer..
