SPEC-2 - The Most Powerful Pioneer Power Amplifier Ever! Vintage Stereo Repair Restoration Testing.

A Pioneer SPEC-2 stereo power amplifier repair and restoration video. Old electrolytic capacitors and heat stressed/troublesome transistors were replaced. The power supply assembly which is known to be heat stressed in the Pioneer SPEC-2 power amplifier was completely rebuilt. The power amplifier and meter assemblies were rebuilt. In addition, the four filter capacitors were replaced. This Pioneer SPEC-2 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 amplifier needed. This Pioneer SPEC-2 power amplifier 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!
