This is a really nice design from a analogue electronic theory standpoint, something which I always have to work fairly hard to try and get my head around.
What would be really great would be if you could give an overview (just a fairly high level of each of the blocks / op-amp stages) into what each section does? I can work out various bits but, for instance, the lower op-amp stage leaves me pondering... Always love it when a service manual has a "Circuit Theory" or "Principles of operation" section adjacent to the schematic, gives you the opportunity to just sit and get your head around something your repairing. I have just finished recapping, retrimming and tidying up my old Thurlby PL series supplies and the design for that can be a bit uncouth in some areas... Impressive stuff though, I would not know where to start (probably with a micro in todays world, sadly...) - Alex On Friday, 6 August 2021 at 05:36:07 UTC+1 threeneurons wrote: > I designed my "Dekatron DoHickie" over 10 years ago.
