Pioneer SX-1050 Vintage Receiver Restoration at Hudson Valley HiFi

[@stephenc2738]

I was a telephone company technician in the 70’s, wire wrap terminals were used extensively on PBX equipment and the benefit was a tight bond and eliminated the potential for damaging or burning adjacent wires and components. There was also an “ unwrap “ tool to loosen and remove the wires twisted onto pin terminals.

Thanks for posting this! I had my SX-1050 restored a little over a year ago and I'm very happy again. I'm an original owner as well, these were quite a beast in their day when paired with good speakers, they had a great FM tuner as far as receivers go. These are like 45 year old old cars now, they need an old fashioned tune-up, change points, condenser, set dwell, set timing, carb mixture, idle...on and on. Once returned to their best, very little beats the way they sound.

What would cause no sound from speaker. If i use the adapter output and have a speaker connected it works. But when i use speakers a b and c nothing coming out

Your speaker protection relay is open possibly due to a fault in the power amplifier. Needs to be checked for DC offset

Does this unit belong to a customer, or will you be offering it up for sale when the restoration is complete?
