Re: Tandberg Huldra 8 valve failure
From previous tests we already know that D702 is OK.
You cannot test C704 in circuit, as it's shunted by one of the diodes in D701. You'll need to disconnect it and retest, but it isn't the cause of the fuse blowing.
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.
While the two caps are disconnected, test C702.
