This amp is part of a range where Sony experimented with switched mode power supplies in amplifiers. Some models also had the experimental heat pipes method of cooling instead of the traditional heatsinks. Great performers, but few were ever capable of fixing the SMPS if it went faulty.
I was one of the very few who could, so I got lumbered with their repairs from all the Lasky's branches. That's why it stuck in my memory.Thanks, yes the PLPS is a big problem with these amps, basically the electronics inside gets cooked as I'm sure you know.One has just recently gone for 500 euros on ebay.de, Hungarian seller.Tony.
Onkyo X-500-This unit is a 4 channel reciever and turntable combo in a floor standing wooden cabinet. This was probably sold around 1973.The cartringe is a CD-4 (4channel) cartridge - (GCJ).There are 7 rotory knobs on the front as well as some buttons. The second to last rotory selector knob (4 CH MODE) has the following positions CD-4, Discrete, Automatic, RM, SQ.This is very similar in function, design,appearance to another quadraphonic system, the Onkyo X-300 and internally they probably don't vary much.There is another floor standing unit called the X-1.

This one is quite a bit different with a different configuration of knobs and buttons. Possibly the X-1 was an earlier model.Please could anyone help with some info on the Onkyo X-500 and posssibly the X-300 which could be very similar.There seems to be nothing on these items.Thanks in advancevintagedan.
