Part 1: DIY Pioneer SX-650 Restoration Project (Working Good Now) - 16 Jan 2022

Rescue unit was very scratchy so cleaned it up real good. More restoration work to follow.

Picked one up yesterday from a thrift store. $7.00 and working!

I bought an SX-650 in 1977 trading up from my SX-434. Got it at Crazy Eddie in NYC and it was boss. I liked the look of this SX-650 and the two big tuning meters, moderately effective (6dB/oct) high filter, smooth effortless flywheel tuning (the pointer glides along the dial), detented tone controls, two tape loops with one way dubbing (rare in a mid priced receiver), a healthy 35wpc, positive sounding and working toggle switches, extra Aux and Mic inputs and that horizontal rear panel for easy hookups. And a really swell FM tuner to boot. Only caveat?? The power and speakers on the same switch, it could lead to nasty (and speaker damaging) sounds as the component aged. I had my SX-650 driving two speaker pairs; Ohm model L's and EPI-100's. The SX-650 had more than enough power to achieve lease breaking levels and impress, if not annoy the neighbors.

THAT is a great thrift store find! Looking forward to the restoration.

I have one of these sitting beside my bench, I bought it a few years ago from a friend for $20.00 ... he siad it didn't work and I haven't yet taken a look at it.

[@johndrx165]

I just bought one. Good stuff!

[@createdezign1840]

It's a shame that you couldn't use real veneer seen that done on a few and it looks wonderful. love your content by the way. :)

I have one of these amps, but the A channel is out, only using B. Curious if there was anything that I should check first. Also the speaker cord connector buttons are in terrible shape. Any advice on those? Perhaps I should just start with a Deluxe kit.

[@niklasbremler2156]

I have one of these, but with a problem. After playing music for a while (mobile attached to AUX), it suddenly goes silent. After a while, the sound comes back. There seems to be a clicking sound inside the receiver when the sound disappears/comes back. This does not happen when the radio is on. Any thoughts?

[@navydiving]

The clicking sound is your relay tripping. Could be your line level board has a fault somewhere. If the radio is good then it tells me your amplifier stage is working. Hard to diagnose with only one symptom though. 🤔

Vinyl is NOT veneer!

Who really gives a shit? (besides you)🤣
