Your comments:

• AVO made a whole range of interesting electronic test gear apart from multimeters... mainly valve based; however their is little or nothing on-line detailing this equipment. Mostly just about the multimeters. I have an interesting AVO Type 1388 B if anyone knows anything about it?. Also an AVO ETM, a couple of VCM valve testers... oh, and an AVO 8 :) It's high time someone (perhaps an ex employee of AVO) could put something on-line about this iconic British ground breaking company and its extensive products.

• Indeed. Still in use in the BBC for the remaining valve amplifiers in some TV monitors and tape machines when I started work in 1978.

• I spent many a happy hour in the '70s, using one of these to test valves for the dozens of "Amp 110b" in the TV Repeater Station at the Post Office Tower.
