Hi Bill.

Do you have the specs on the old buzzard RCA Open Frame
500Watt Modulation transformer?  You know, the one that
has the tag on it (some red - mine's black with white letters)
that says "Secondary Maximum Current 0.98A"?

I have used that transformer with a pair of 250TH's, with 
no problems (and capacitivly coupling audio to the B+ line,
on the high-side of a choke, used as a modulation reactor)
but am curious as to whether the specs, or practical experience
thinks that the Mod-frmr will hold a pair of 450TL's.

thanks!

73 = Best Regards,
