Unidentified KiCAD Power Supply Design - possibly for Valve Tester?
Hi!
I found this KiCAD 4.0.7. Power Supply PCB file on my One Drive but I can't find out for the life of me where its from - from the lettering I got from the circuit diagram that doesn't import properly in the current KiCAD it appears to be a H.T. power supply PCB for a valve tester - does anyone recognise the design and can point me in the direction of the site the file came from please? Chris Williams

Re: Unidentified KiCAD Power Supply Design - possibly for Valve Tester?
. . .It was when I noticed the five 51 V zeners I thought it might have been from the Sussex, but I can't seem to pinpoint where I found that KiCad board from, as the current Kicad couldn't read it – I'd to download 4.0.7. to get the screenshot!

The IRF540 MOSFETs would not be my first choice if I was designing a high voltage regulator.
Could it be an inverter? |

Re: Unidentified KiCAD Power Supply Design - possibly for Valve Tester?
I'm 99% sure that is my PCB design for the Steve Bench RAT valve tester that I built some years ago, for those that don't know where the term RAT comes from it refers to a discussion group called (I think) Rec.Alt.Tubes from the 'old days' of computing before forums such as this one became popular.
On the board are the anode and screen supplies, bias supply and a 100mV 1KHz signal gen. I'm unsure how long ago I drew the design it's probably done with Kicad 6, since then I've moved from Windows version 7 to version 10 and I no longer have the Kicad files on my present PC setup, having backed everything up to a 1TB portable drive. It easy to get the board mixed up with the Sussex as the anode and screen variable supplies on Steve Bench design are just about identical to those of the Sussex. |

Re: Unidentified KiCAD Power Supply Design - possibly for Valve Tester?
Just created a quick Kicad V8.01 project for Y'all. Attached as a zip file. Just made a root schematic with the schematic diagrams/gif from the link in the last post pasted in. All you have to do is recreate the schematics and then you can do the PCB.
