Restereo comes from our want and need to buy and repurpose items with forgotten value. First we search far and wide until the end of the earth for the primo vintage iconic or forgotten American craftsmanship. Second we buy it and stare at it until an idea explodes into our minds then effortlessly extrudes itself onto paper. Then we either ball it up and throw it into the trash, or hang it on the wall for further examination, scrutiny, and possible development. Thirdly we take the ideas and pieces that stand out and start to hand craft them into the stuff dreams are made from. We gently and sympathetically restore, remodel, and rewire vintage audio into modern American made beauties ready to sooth or motivate any enthusiast to "retreat into sound".


Restereo designs and restores one of a kind antique Hi-Fi audio tube amplifiers, speakers, and accessories for the modern audiophile. Restereo selects only the finest American made vintage audio pieces for an expert sympathetic restoration, preserving the character while vastly improving sound quality.

Introducing the Hammond Solovox Tone Cabinet Model L. Made in 1948, this was the tube amplifier and speaker for a unique small Hammond Organ. Constructed from mahogany and brass, these were beautifully engineered for optimal sound quality. A classic piece of American craftsmanship.

We here at Restereo rewired this Hammond Amp into a class A single end amplifier for your Hi-Fi listening enjoyment. The unit boasts a powerful neodymium magnet full range speaker for sensitive, clear sounds and modern bluetooth & airplay technology allowing wireless streaming from your choice of device and platform. An auxiliary port was also included for a secure wired connection.

Pre-Amp Tubes

The Hammond is outfitted with 6SN7 NOS American made tubes. 6SN7 is a dual triode vacuum tube with an 8-pin octal base. It provided a medium gain (20). The 6SN7 is basically two 6J5 triodes in one envelope.

The 6SN7 was often used as an audio amplifier in the 1940-1955 period, usually in the driver stages of power amps. The designer of the famous Williamson amplifier, one of the first true high-fidelity designs, suggested use of the 6SN7 in his 1949 revision.

Power Tubes

Each Restereo unit comes equipped with high quality new old stock tubes.
