This is basicly the same as a LS-63 with an added 500 ohm winding , i finally got a a second LS-63 or i wouldn't let this one go .

$300 with shipping in the US .USEd in very good condition

Would have sold the LS-63 if i had gotten a second one of these first , the 500 ohm winding would be great for headphones .

Plan on using the the LS 63's with 300B pp output tubes but these also can be wired to use then as single ended output transformers for 2A3's and 300B's according to the literature due to the permalloy core that is semi-toroidal wound

"According to the literature"?- Where do you find information like that?
I've got a pair of LS-6L1's that I want to make sure I do right...when I get around to them.

I will have to find where i put it but you connect the two plate windings in parallel connect pin 1 to pin 3 and pin 4 to pin 6 which will parallel the plate windings for singled ended use . the information came with the nos LS-63 when i got it a couple of years ago .

i live in Alton Il not to far away from you
