Vintage Tube Amp

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.

This Amplifier is brand new. The previous owner bought it and never opened it. It has been sitting in his basement until he unfortunately passed away. It has that vintage smell also, and I will not charge extra for that. You will never find this Amplifier new in the package anyware. This is a rare find. I was going to keep it.

This receiver has been fully cleaned and tested! All tubes tested strong! All pots an switches have been deoxidized allowing for smooth and crackle free adjustments! All capacitors have been tested and replaced as needed! If you have any questions please feel free to ask!

I bought this piece all dusty and without been used for years from a garage sale a few years ago, it had one broken tube. I’m adding pictures of the old capacitors, the old tubes (two are MULLARD Fat Brown base EL34 Xf1 still good and the other two are old xf2 black base EL34 tubes), the receipt for the service and a Manual I print out.
