I shouldn't think it too onerous to have a class table where voltages are one style, currents another. Resistor colors sans white could be used: v1 black, v2 red, v3 orange... - Ian Jan 4, 2025

Yup, tube amps really are different from their younger cousins! EL34world.com is a great place to learn about this stuff. Well informed folks over there. Also, theampgarage.com is reputable. chris

thanks for the additional information. I found the datasheet for the transformer, and collected the DCR values and needed voltages. I adjusted the PSUD2 app values as you suggested, and I removed the

Sounds good, please use the ohms from one leg only, not across the whole HV winding (it's to do with the way PSUD2 works). Also please factor into account the resistance of the primary to give an

Excellent suggestions! thanks! I did not know that about the zeners. I have used them before on other projects, and felt like they worked okay. Other amp builders turned me on to the zener trick. I

Hi, A couple of suggestions that might be of some help: In PSUD: * When you start up, there will be some large peak currents. You might want to use "after a reporting delay" and pick 1 second to work

Hi all, I am attempting to understand this PSU2 app. I want to design a power supply for a tube amp that has a B+ of around 350Vdc, and B+1 at about 330Vdc, and my final B+2 (preamp supply) at about

Hi Paul, I had a look over at the Appimage site and for sure it's aimed at aligning different Linux distributions rather than different OSes. That in itself might cause problems with the binaries as

It seems to run "on many Linuxes"; no mention of Mac or Win. "It aims to allow the installation of binary software independently of specific Linux distributions... one AppImage can be installed and

Thanks Duncan, I don't know much about Appimages or how much work creating them involves, but they seem to run on any OS without installation, which would be ideal for PSUD. Richard.

Hi Richard, Good question - let me look at this. I've got a few days off over the Xmas break so hopefully should get some time to investigate. If it's doable, it's going to be a zip or tgz that you

Sorry, I should have said " Is there any chance of an Appimage for Linux", but I assume the answer is the same. Regards, Richard.

Hi, Is there any chance of an Appimage ? Richard

Hi Francois, The MacOS version is no longer available or supported, sorry. Regards, Duncan

I’m looking to download the software for MAC but somehow I can’t find any software download on /g/duncanampspsud Thanks

The classic definition of Power Factor I learned as a boy applies to Linear components (L R C) and continuous currents (no rectifiers). Same for "lead/lag": does not cover the case of rectifiers. The

On a simple FWB rectifier with a high? C filter cap....... is the result? ?RMS? I(C1).....? the same as the AC ripple current going into the cap ??? On another note ( using the same above
