Save, restore, upgrade your Pioneer SX-1280 receiver. For sale, a brand new power supply pcb, fully assembled, tested, including burn-in. This improved design addresses a number of reliability issues regarding the original design. It is a double sided pcb, 1.

Green solder-mask, silkscreen printing for component identification. All high quality parts from leading manufactures. We also sell the un-populated blank pcb in another listing.

These are built to order. 1 One fully assembled, tested, pcb assembly that is the exact same size/dimensions as the original.

2 A full set of documentation and notes. It is an improved version over the Pioneer version in a number of ways. 1 The pcb material is much better, higher temp FR4 epoxy glass construction, LPI solder mask, double sided THT, silkscreen legends. 2 Changed the +/-88V regulators to be the same as was done on the SX-1980 re-design which uses a constant current source using LEDs/BJTs instead of the failure prone jfets, 50W MJE1503x bjts. 3 Panasonic 16A relay, all new semi's, precision resistors, Nichicon and Vishay 105c ecaps. 4 3 terminal regulators for the +/-32V and +13V reg, which are precision regs with over current protection. 5 There is an lower cost option to stuff the original zener design for the +/-32V, but do not suggest this and recommend the improved 3-terminal reg design.

6 Higher performance heatsinks to run the devices cooler. 7 Easy installation/service, using terminal blocks with screws downs for binding. The item "Pioneer SX-1280 AWR-157 power supply pcb, fully assembled, tested (new)" is in sale since Friday, January 31, 2020.
