I am selling two fully rebuilt and restored Pioneer SX-950 stereo receivers. Both receivers are cosmetically 95+% and have undergone extensive restoration. They now feature premium replacement parts, including updated transistors, Zenor diodes, a repaired and upgraded protection relay, all major and known problem capacitors, all-new incandescent lamps, and bias and offset trimmers. New 5-way speaker binding posts have also been added. All films are premium, non-polar, and far exceed audio grade. For the phono preamps, capacitors for the audio path have been upgraded. All major capacitors have also been replaced in the unit. With all this high-quality work, these units will last for many years. I guarantee these units for an entire year from the date of sale, but I will work with the buyer after that if any issues arise. A list of all restoration work done, including replaced parts, and the restorer's contact information will be provided upon request at the time of sale. Buyer's choice-$1175.00 each or best offer. These units are located in Corvallis, Oregon. Please, NO Texts! Calling is best, but I will promptly answer all emails that include the sender's name and return number.

Restoration Work Includes:

Replacement of all electrolytic capacitors with high-quality Nichicon FG, KL, PW, ES, and Panasonic FC, FM, and FR series

Replacement of all tantalum capacitors with either electrolytic or film, depending on value.

Wima poly capacitors were used throughout the audio circuit.

Film bypass capacitors are used on the main rails

Replacement of all Zener diodes

Full bridge rectifiers rebuilt using ultra-fast diodes

Nearly every transistor in the power supply was replaced using better and more robust devices, and a new thermal compound was used.

All known trouble-making transistors were replaced. Many transistors throughout the audio circuit were replaced using low-noise devices & faster devices were used throughout the amplifier.

New output transistors using Onsemi MJ21195 and MJ21196

All controls cleaned using either Caig Deoxit D5, F5, D100 or F100 depending on the control

All new incandescent lamps were installed

All bias and offset trimmers were replaced with new Bourne trimmers

Relay rebuilt and contacts polished

Original substandard speaker posts were removed and replaced with custom 5-way binding posts.

Adjustments of power supply regulated voltage, output bias voltage, and DC offset.

48-hour minimum burn-in, power measurement, and measurement on the audio analyzer to measure THD, THD+N, and frequency linearity to confirm it met or exceeded factory spec
