Not sure what you mean.
Building a new power amp?
It may be an option, post some gut picture so we see layout and available space.

But first I'd try to replace SAP with some similar spec power transistor, and add the biasing diode string plus external wirewound ballast resistors.

Would be the least work option.

Not everyone uses Facebook which I assume is why none of the links work for me.

Its much better to attach pictures directly to the forum and thread in question.

To add a photo, files or non standard files.

First click "go advanced" in the box below the "quick reply" message box. Doesn't matter if you decide half way through a message to do that, it carries it forward.

Then click "Manage attachements". Maximise the new Window so that you can see all the text.

Click browse in the first box at the top and find your picture. Repeat for any more pictures.
Click upload... a message appears "uploading"
When complete the files will show as being attached. Now click the small text that says "close this window"

The pictures should now be attached and when you submit your post they will appear.

Make sure your pics aren't too big, a couple of 100k is plenty, and many members object when they are massive and it alters the margins
It tells you in the attachments window what max sizes are allowed.


If you want to attach a file that has a non standard format for example excel, circuit simulation etc then try putting the files in a zipped folder and attaching that.
