Hi, There's a note in the files area, however it is pretty vague as it doesn't give any OS version numbers: I'm not sure how far back PSUD will work as I only have the one MacBook Pro to support this

Hello: Downloaded Mac OS builds 75, 77 neither worked- "the following disc images couldn't be opened" psud2.build77.dmg- no mountable file systems I'll assume my mac is too old?- 3.1 macPro running OS

Look at the tab FILES see photos Dan

Hi, You posted on 21st March last year that you couldn't download it. I asked for some more info but never got a reply -> /g/duncanampspsud/topic/97773153#205 You raised the exact

Hi i tried to download psud2 but its dont work ,do you have a problem or something ,regards

OK that's a good bit of info, thanks. It does make me concerned though, as the model is the same for all the diodes; solid state as well as vacuum tube. At least I can duplicate the issue at this end,

I noticed it seems to be related to the valve diode model, as HV valve diodes (eg. 575A and 3B28) show symmetric behavior.

Duncan, thanks for taking a look.? No rush from my perspective - just wanted to confirm there was an inconsistency - it's an esoteric situation, which is likely why this may be the first awareness of

Hi Tim, I've duplicated your circuit using the values listed in your message, and I can confirm that something is badly broken. Looking a I(T1) the positive and negative excursions should be the same

Hi Tim, Thanks for letting me know. I'll try and duplicate your circuit this evening and see if I can find any clues as to what's happening. More news later... Regards, Duncan

Duncan, seems you're busy with V3, but perhaps you have time to quickly check an inconsistent response when using a valve based voltage doubler.? I have a setup with 330V 21R secondary supplying a 2x

Hi Duncan, I'm so glad I found this. I used the original PSUD almost 20 years ago now and it helped so much. After this long I'm building valve amps again, but the computer I had the original software

Agreed as well! Thank you Duncan! "Conan, what is best in life?" "To crush your code. To see it working before you. And to hear the adorations of your users!"

I wholeheartedly agree. The SW program is a wonderful tool and it's especially nice that Duncan continues to improve it.

I hope this message isn't a bother to everyone, I just wanted to say thanks to Duncan for making this software available. I have been playing around with it for a bit, and and it's great! Thank you

Hi, you indicated issues with downloading the software on 21st March, however I did not hear back to be able to assist with the issue. The original thread is here -->

Hi Dom, Thanks for the offer. I've paused the PSUD3 Beta at the moment, there has been some really useful feedback on it which I will incorporate over the Christmas break. There's a message with a bit
