Does anyone have any audio impedance matching transformers and is willing to
sell them? Specifically I need four 4-ohm to 500- (or 600-ohm and one 8-ohm

or 8 ohm primary, that will do too...my need is not critical. Thanks!

My suggestion: get speaker transformers for 70V distributed PA systems and
run them in reverse. Your local installed sound place will probably give
you a bunch of scrapped ones for free.

And if not, then they're not at all expensive new, whether from Radio
Shack or a full-service electronics shop. They tend to be 600 Ohms to
16/8/4 (and a slew more) Ohms. If you're in the UK, Maplins may have
them, or one of your mail order houses. Here in the US, I get mine
from Radio Shack locally, though Mouser, Allied, and Jameco also carry
them via mail order, and Cinergy (formerly Radio Supply) in Oklahoma
City sells them, too.
