[R-390] Never heard the real R-390

[Laird Tom N]

AES part number: P-T119DA ($18.32) www.tubesandmore.com

quote:

Developed in response to requests from the "Collins Collectors Association", this is a matching audio transformer for older equipment with 600 ohm audio output, driving modern speakers. 

Or for "classic" high impedance speakers used with newer equipment, simply swap primary for secondary (ie...4 or 8 ohm input and 600 ohms out).

the one out of the LS-166
