Pioneer SX-626


A medium-powered stereo receiver with up to 110 watts of music power, low-noise FET, and high sensitivity FM tuner section.

The SX-626 stereo receiver is one of Pioneer's great stereo values. In one attractive, well-designed package, it offers the hi-fi enthusiast everything he could possibly desire in a medium-range power unit.

Including up to 110 watts of power (at 4 ohms), an FM tuner section of excellent selectivity and sensitivity, high signal-to-noise ratio, and two tape monitor circuits that permits tape-to-tape duplicating.

The SX-626 is powerful enough to operate a pair of large speakers, yet it's also versatile enough to handle small- and medium-range speakers for the man who's investment in stereo must be budgeted.

Received one of these free from our local recyclers...it had been thrown into two dumpsters at various times, so its wooden cabinet was not at all pretty any more. But plugged it in, powered it up, and except for one dark dial lamp, it is 100% on task! Who built these things, I wonder? ;)

Excelente sección de AM, esplendida construcción, se puede mejorar el desempeño sustituyendo el capacitor principal por uno de 6800 uF X 63 Volts, sonido de primera.

For its time a worthy receiver. Recapped the unit, but it wasn't really necessary. Single rail power supply is well suited for its task. FM reception is excellent. Lacking is a center meter, which I kludged in with LEDs and opamps. Signal level meter was pretty much useless. With extra diodes managed more logarhythmic response. Also replaced the tuning dial lamps with blue LEDs. The result is absolutely stunning! See gallery images.

re: SX-626

Excellent receiver for those that don't need a monster flame throwing 150wpc (watts for channel) receiver. Bought mine on eBay cheap. Had to replace the dial pointer lamp. Also replaced the dial lamps with LEDs and as another poster said: AWESOME! Thought about re-capping it but all the capacitors were quality ones and since the unit sounded good I didn't. There was a power filter cap that was leaking so that got replaced. All the other caps looked good with no residue on the pcb (printed circuit board). Highly recommended unit.
