Good will do, good notice on the fuse :) Thanks
Ordered the parts, will keep you posted !
simondwilliams:
Ok tried to replace fuse and the ceramic that blew up but nothing to do the fuses stills blows. I messed it up without the isolation transformer...
grantspain:
the big ceramic resistor mounted on the frame looks damaged
i suspect the bridge rectifier at d601 is also bad
lots to go wrong in the power supply section of these
where is that burnt out terminal block with the blue wire going?
simondwilliams:
It was to that Big ceramic R601

i think the schems are not correct, my chassis has a 12 ohm 30 watt resistor
when you removed the old resistor the value should be printed on one side
do you have a str ic at ic601 or a transistor at q601- there are two very similar models and this helps id it
