Re: AVO instructions for creating a standardised valve.
My test setup (i have a ct160 also) is a Solartron variable ht bench psu and a Farnell E30-2 for bias. I use a 10k 10 turn pot for bias, with the supply to it around 25% more than the highest grid voltage required. Voltages are monitored with 2 Fluke 77 and a Wavetek dvm for Ia. Tests are done at the Avo CT160 book test voltages, with Vg swung 0.5V either side. This is pretty accurate.
However, you still find that there are people out there who will reckon their Acme mickeymouse tester results are correct and my digital readings must be wrong!
