Re: Valve Testers
As a side issue the NZVRS bulletin had a replacement idea for the rare meter that goes bung in an Avo valve Tester (CT160) as it's some odd current like 33 micro amps FSD - basically, if memory serves me correctly, it used an op amp feeding into a more normal range meter. The point being there are work arounds even for the burnt out meter Avo testers - not that anyone selling one will ever admit the tester is in anything but excellent working condition.
