PIONEER SX-800 Receiver Amplifier Description

Pioneer SX-800 Receiver Tuner Amplifier 7189 12AX7
Sx 800 Pioneer Rare Tube Receiver

The preamp 12AX7s seem to have most effect on sound. The on off knob may not be original but it fits. I'm a budget tube roller and Soviet 12AX7 laps are my favorite, however they not included. Best with efficient speakers as its under 30 PC but sounds sweet.

Phono works nice as well. The speaker connections have been upgraded with a banana plug style. The 7189s seem very stable. The inside has some rust spots.

The 2 preamp 12AX7s included were purchased on as GE with no lettering. Tubes aren't tested but have sounded fine for hours. Very heavy and will be shipped in a large carefully packaged box. All electrolytic capacitors have been replaced, a dozen ceramic and many faulty resistors.

Please really inspect pics for condition. Tubes are a mix of GE, Hitachi, Mutsuhito and others. This machine is very stable and can be used all day night. Can caps are Ritchie and J multi-caps not stuffed.

This thing pulls stations without an antenna. Main use was aux with an iPod. Much better with one though. I'd suggest getting a fresh pair to experiment with.

The outer cosmetic condition is presentable but not perfect. Shipping 80 east of the Mississippi 60 west. Large rubber feet were added. Heres a rare PIONEER SX-800 receiver based on 7189 tubes.
