Default Re: Tandberg Huldra 8 valve failure

Forgive me if this has already been tried Clive but have you tried measuring the resistance across C702? Hunts smoothing bomb

It's very difficult to read the value of C704 from the pictures. Perhaps the OP could advise? Station X

B]The results of testing C703 indicate that current from your meter is flowing through D702 in one direction and possibly down to chassis via a possibly faulty C702. Disconnect one end of C703 and retest it. Station X

Any chance of a close up photo of the original fuse that blew? It might give an idea as to the severity of any current flow at that time etc.

i put the quotes in to make sure i answered some of the questions see the latest photos, a couple more photos in the next post from me, i removed some wires so i could get out C703 out of the circuit otherwise very tight in there. i just recently looked at "just radios" looks they will be able to help when i am ready.............as they say when in crisis "put the kettle on"
