hi .no jts not that model .apparently and confusing the san diego dj name was used on different models.i did struggle to find a schematic when i was trying to sort a previous issue of distortion on cassette only .i can find a pic and email it to you if that would help ?

The circuits seem to cover lots of models - all basically the same, but followed by another city or state name. Cleveland, Dresden, Boston, Madison, Freiburg, Las Vegas, Canberra, San Diego, Essen, Alicante, Lausanne, Konstanz, San Remo, Santa Cruz, Dusseldorf, Kansas, Bologna, Hawaii, Maryland, Munchen or Modena.

Is there a numeric part number on the radio? I think the San Diego DJ RCR 127 should be "8 646 713 310"

on the side it says
7 646 764 310

ok so slight update on this !
the unit has worked fine in the house every time and could  continue for some time (or go faulty tommorow !)
so .as i have a few of these units i went back to trying to solve one of their other common issues which is distortion on the cassette playback .( i have 3 that do this)
this started years ago and i never solved it then (just bought a replacement off ebay)
the radio section is fine and the cd control section is all fine and crystal clear . the cassette is distorted .my replacement unit has gone the same too !
i have spent every evening with a perfect deck and a faulty deck swapping components but to no success .
so far i have swapped 1st stage preamp chips ,second stage transistors and virtually every electrolytic including all the coupling ones in the sound path between stages .i have even swapped the tda4748 main ic (that was a bugger) between units andcthe distortion still stays on same unit .
tried tapping the left and right channels off into my domestic hifi amp and the signal is crystal clear .
so its crystal clear where it goes into the tda ic but the tda distirts it but the ic is ok ?
ttied powering the cassette motor from a 9v  battery too !
messaged dave dnd fof advice but not interested !
so any other pointers  OR are there any radio repair engiineers who i could actually visit and go through it with me ?
help !!

The cassette motors generally have a sub board in them to regulate the speed, so check the motor (or swap it) and also check the mechanism for dry grease, tight spindles etc

tried that .the complete decks were the first thing i swapped !
its as if the coupling capacitors are faulty but swapping them unit to unit doesnt swap the fault !
its very frustrating !
