Circlotron Schematic similar to OTL.

Are: 2X EL84 ; 1X 12AX7 ; 1X 12AU7 ; 1X EF86 ; 1X GZ34. Two Mono Power amplifier. Output Power: 18 Watt for each amplifier. Ultra Rare in pair!

Good sound, tested on CD and vinyl. Volume, bass treble ok. There are stains inside the device but does not affect the sound quality.

We love putting cool stuff in the hands of people who will love it, and keeping history out of the landfill.

Has slight surface rust all over. The screws that hold cover on were missing so I put 4 in, but not original.

For sale is an Audio Research Dual 75A factory upgraded from a Dual 51 Chassis. This upgrade must have been done back in the 70s as the tubes are all US made, not USSR/Russia like in most ARC gear. The cost of these tubes alone would be likely half the total cost of the amplifier if you were to replace them.

This vintage Sherwood S-5500IV stereo amplifier is a must-have for any audiophile looking to add a touch of nostalgia to their collection. Featuring a brand name that is synonymous with excellence, the Sherwood S-5500IV is a vintage amplifier that has stood the test of time. The perfect addition to any vintage audio setup, this tube amplifier is sure to impress even the most discerning of listeners.

Consider that if you have an allergy. Everything pictured is included, no screws for the cover.
