I have been starting to collect a few old receivers this summer. Nostalgia for the days of listening to my dads Pioneer SX-980 as a kid, and a general interest in electrical stuff has brought me to this forum. Recently I have been finding some smaller less expensive receivers to get my feet wet. So far I have picked up a Technics SA-200 which just needed to have the pots and switches cleaned. I also found a Sankyo SRC-4040 which needed cleaning and also bulb replacement. The third is a Wintec Model-333. It plays alright, but has some offset in one channel. Hopefully I can find a service manual eventually to help with this? Yesterday I picked up a Pioneer SX-737 which I believe is being cut out by the protection circuit. I am thinking of taking the plunge into my first recap with this receiver? I have been reading lots on this forum as well as the service manual. My plan is to try to fix the cut out issue first, and then go ahead with the recap.
