If you right-click on the rectifer area when it is lit up, it should allow you some different choices.

I can see a couple of potential issues:

1. The transformer voltage should be the off-load voltage rather than the rated voltage. If you can't find out from the transformer manufacturer, try taking the rated voltage of 240V and adding around 5%-8%
2. I think 96mA is a very high current draw for a single 6V6 and an EF86, I would be inclined to go for around 50mA in the absence of solid data

Try those and see if the results end up being closer to what you expect.

I do not understand how to change the default bridge rectifier to a
full wave. Trying to get my first PSU designed

Hello

Thanks to group members answering my previous Q - adding sections and solved by tapping on a Mac trackpad (!)? Yep, I had no idea.

However, and having reviewed the available documentation on PSUD2, that I can find, anyway, I'm still in a quandary about what to 'look out for' and how to actually i.e. practically go about designing a 'good' 'good enough' PSU??

For instance, although it's a simple task for me to measure primary and secondary winding resistances, I do not know the % regulation of my Trafo.? Nor do I understand the application or function of 'current taps.'? Is my 'final' load - 5kΩ or 86.5mA (the combined load of a 300B and a 6N8S / 6H8C?? To me all these things are still mysteries.

has helped me, a little, thanks DHTROB, but maybe I''m just not 'clever enough' or cut out for this kind of thing and perhaps there may be other people in similar difficulty?

In the corporate world, I suffered with McAfee, Norton, AVG.

As a developer, fewer install problems from MalwareBytes using customers, but that could be due to market penetration.

MalwareBytes outshines all the others on our personal machines. First used in the early '00's.
IMO, the best support when needed, the least intrusive, plays well w almost installers.
AND group pricing for several PCs, not a separate license for laptops and desktops

Not to sound like a shill for Malware Bytes, but I've been using them for years, first the free version and then the paid version
It seems to work well and doesn't seem to interfere with my downloads

Thank you for the reply.? For others who might be interested: turning off McAfee to install does work and the program works.? Until McAfee resumes.? Then it kills the program requiring a new download and install.

Apologies, I was about to reply but you have summed it up nicely Paul.

Yes, for a few years MS throws an error message when installing uncertified software. I'll sort out the Microsoft certification and code signing bit in the fullness of time, there are quite a few hoops to jump through:?

My own experience with AV software on Windows hasn't been great; AVG and McAfee have hit me with a number of false positives in previous years so I just use the Microsoft Defender that's built into Windows these days. However, it's a matter of what your comfortable with.

since updating my computer, the new download of spud doesn't work.? McAfee blocks it.? Tried on two computers.? On one it says incompatible.? On the other McAfee stops it.? The download worked fine.? Opening the app doesn't.

Duncan may be busy. I done some software support and know the usual questions.

What version of Windows? 7, 8, 10, 12?

"incompatible" MAY just mean that Duncan has not paid Microsoft to be developer certified. This is mostly about MS being monopolistic. There may be a way to tick-off "run anyway".

As for McAfee... &^%$#@! It was a good idea 20+ years ago. But now McAfee seems to cause more problems than cures. Between the software with Duncan's own name on it, and software from a marketing machine who took-over from a madman, _I_ would turn-off the McAfee for long enough to install PSUD.

First post here: since updating my computer, the new download of spud doesn't work.? McAfee blocks it.? Tried on two computers.? On one it says incompatible.? On the other McAfee stops it.? The download worked fine.? Opening the app doesn't.? Any suggestions?

Hi,

You're going to need to give a bit more information. Did it:

• Fail to download - please provide the link you used for the download
• Downloaded but failed to install
• Installed but failed to run
• Ran but didn't work correctly

Also if you could tell me which operating system you have, that would be a help too.

Regards,
Duncan

Hi Jay,

Go to the website?/g/duncanampspsud?then down the left side, you will see the files area. Click on that, then click on the link for psud2_windows. Click on the build76 file and it will download for you.

Regards,
Duncan

Hi Chris,

Something similar came up a couple of years ago, it involves a slight tweak to the MacOS settings. There's an article on it here that shows the exact same problem, and then further down, how to fix it.?/g/duncanampspsud/topic/77707176#16

as far as i know, all?versions of OS X were 64 bit. 32-bit apps are something else?–?OSX Mojave (10.14.6) was the last macOS that could deal with 32 bit software. all newer macOS are 64 bit only.

I have version 10.12.6 Sierra on my main Mac but I have High Sierra on another Mac and a later one (?) on my Mac Mini
