First on the list, the S-271-S. Specs copied from one of the current dealers:
Peerless 20-20 Plus series S-271-A
configure as 5000CT:16,8,4,1 ohms, 200 mA, 80 watts
or 1250CT:16,8,4,1, ohms, 400mA, 80 watts
Price $1200 the pair

I am sending the 271 one off *NOW*. If anybody wants one for themselves, scroll down, there's more ov course.

Second, the 20-20 Plus S-226-Q. 20W, 6k6 a-a to speaker.
And of course the 5k and 6k6 20-20's the S-240-Q, and S-230-Q.

The 271 is a bit much of a load for a low voltage, U-L 813, but it's not too far off...

Just to restate the relationship between myself and the winder( Heyboer I am a customer. I am not profiting from this relationship. I pay and they wind. Actually, they wind, and ship the parts, and *THEN* I pay. This is actually costing me money, but there is no reason to charge other DIY-ers more than once for the same stuff.
cheers,
