Scrubidubi, I have SET amplifier based on 300B tubes with high efficiency horn loaded speakers. I have achieved great sound from my set up using 12/36 (12 strands of 36 AWG) cotton wrapped LITZ wire. My total cost was less than $300 (plus one day of my labor) including the purchase of the soldering tub for the proper LITZ wire termination.
Just my 2c.
