I have a couple of these that are surplus to my needs, but they were
designed for an electric organ and the secondary impedance may not suit
your requirements. What is the impedance of the speaker you wish to
drive?

I'll have to check in the attic, but I think I have a pair from one Sherwood
amplifier and a single one from a mono Sherwood. IIRC, these have 4/8/16
ohm outputs.

This is a Fisher X-100-B amp with the usual 4-8-16 ohm taps, so I need
at least 8 ohms to be somewhat compatible. Ken

That would be perfect. Let me know if you find them. Ken

OK, mine won't work, they have only a single 16 Ohm secondary.

The monoblock transformer is the one in the best shape, and also the
largest. It is from a Sherwood S10002 an has the taps previously noted.

The tranny is about 3.25" thick through the bells. The core is 3.75" long x
3.125" high by 1.375" thick. It is designed for about a 2" x 2.75"
rectangular chassis cut-out, but could also be mounted above the chassis
with the right bracket.

I'm willing to swap for good 7591s in lieu of selling it.

E-mail me for particulars.

Jon, I have a couple 7591s, but they're the only spares I have. How much
would you want for the xfmr cash? Ken
