Description: Buy-it-Now listing for an excellent vintage Pioneer SX-780 stereo receiver at 45 watts per channel. Amplifier DC offset has been set to factory specs; tuner has been aligned; dial lamps have been replaced with warm white LEDs; all controls are smooth and quiet; all inputs and outputs have been tested. The receiver is in great condition with few signs of wear. I deal mostly in audio equipment from the 70s and early 80s. To me (and many others) this is the golden era of audio, where much of it was built heavily, with a good design, great sound and stunning appearance. There’s a minimal amount of intrusion during the process of refurbishing this equipment. The reason for this is based on my own buying preferences. Claims of “totally recapped” make me a little nervous as a buyer because I know how intrusive a procedure like that can be. The whole recapping procedure is puzzling to me - in my earlier days of repair work, I would suspect bad capacitors and pull them, only to find that nearly every one I removed tested better than spec. Now, as a rule, I don’t replace capacitors unless they are found to be defective or of it’s warranted by the audio waveforms I observe while testing the receiver. It’s my preference to buy items like these that are as close to an untouched original as possible. I realize my buyers might share that same opinion. When possible, incandescent lamps will be replaced with LED equivalents. The reason for this is that incandescent lamps are short-lived and may have trouble surviving the shipping process on its way to the new owner. LED lamps also have a typically longer lifespan and generate much less heat, which can dry up and damage the area surrounding them. Lamp replacement normally involves no permanent modifications, keeping the equipment as close to original as possible. I typically replace dial and function indicator lamps with LEDs. Original electronic components are replaced with parts that are of equal or better quality/performance to get the equipment back in working order. All functions are tested to make sure they operate properly. AM/FM tuner is aligned. Amplifier DC offset and/or bias are adjusted to factory specs. A signal generator and oscilloscope are used to make sure the signal coming out looks like the signal going in. Testing with this equipment verifies correct operation of the preamp and amplifier sections and ensures audio clarity. For receivers, new boxes are purchased specifically for them, with extra room allowed for cushioning material. A Styrofoam sheet is placed in the bottom of the box for support and rigidity. Receivers are first wrapped in several layers of bubble wrap, then placed in the box. Multiple layers of carpet padding are placed in all four corners for cushioning. More cushioning material is used to fill any remaining voids. I don't use Styrofoam peanuts or any other "loose" material. Items will be shipped insured for the amount of their purchased value.
