Now the main problem with the CT160 is there is a fair chance that the meter is toasted. The measurement procedure calls for the anode current dials to be set to the AVO book value, the assumption being that will be within a few mA of correct.

But - shove in a KT88 or similar that is shot and has low emission - and the meter pegs and burns out really fast.

So - I'd feel miffed if I had stumped up £500 plus for a non-functional CT160.
