General repair of valve HI watt valve head...

This one came in dead!  1amp ht fuse o/c plus valve fault fuse's o/c.. main problem was rectifier diodes s/c.. so after replacement and tube checks all ok... then move on to soak test for a few hours...

So after a two days of checks to ensure things run smooth then back to the local studio...

A month later I got a call...'that head is not working can you sort it?  sure, be round to sort it...

Turns out the studio has been have power surge's and different amps have been acting up...

There getting the sparky's to check the place over ;)
