Mike, I have had another look at the 1A2 and found that I hadn't sufficiently cleaned off the green corrosion. After a thorough clean, I tried this valve and lo and behold it is serviceable after all. I will try to get my Avo VCM out tomorrow and compare with the DK91. One thing that is evident with the 1A2 is that it seems more microphonic compared to the DK91.
For better stability, I think the circuit would benefit from being mounted in a screened box.
Regards
Symon.
