SX-1250 - The Best Pioneer Receiver Ever? Vintage Stereo Repair Restoration & Testing.

A Pioneer SX-1250 stereo receiver repair and restoration video. Old electrolytic capacitors and heat stressed/troublesome transistors were replaced. The power supply assemblies (AWR-106 & 107) which are known to be heat stressed in the Pioneer SX-1250 receiver was completely rebuilt. The EQ amplifier, flat amplifier, tone control amplifier, protection circuit, and power amplifier assemblies were rebuilt. The troublesome push button switches in the speaker assembly, filter assembly and function switch assembly were cleaned with Deoxit as well as the other controls. In addition, the four filter capacitors were replaced. This Pioneer SX-1250 was then bench tested with an audio analyzer. This was a top to bottom repair and restoration that after 40 years of service this vintage receiver needed. This Pioneer SX-1250 receiver now sounds great and will be reliable for decades to come.

I am a hobbyist that repairs and collects vintage stereo gear. Every piece of equipment that you see in my video's is mine. I don't repair other people's equipment and then send them back to their owners. I repair, restore, and bench test every unit. I then install each unit into my own stereo system and do what they were meant to do. Play Music!
