[QUOTE="El Sid, post: 1054003, member: 18550"] A bit of an update here - prompted by [member=21666]Zilch[/member] who was keen to buy one of these units, I carefully fired them up on the dim bulb limiter. There were no fire works, and both sort of worked. So the one went off to Zilch and I?ve been working on the other. Unfortunately the circuit diagrams I found for similar units are quite different from this South African unit, so I have no circuit diagram to work with. The audio section was fairly easy to sort out - replace a few caps and the odd resistor and it?s ok. The radio sort of worked on AM and FM. I tried an alignment but it didn?t really help, hampered by not knowing exactly which IF transformer was which. So I?ve decided to bite the bullet and trace out the circuit diagram. For this.
