Any idea where the "manual" you speak of might be located?

Maybe the LA-3A service manual??

UA's service manuals are usually pretty detailed.....

Although I'm not sure if this "clone" is different in many ways....

Hi everyone,

Here is a google drive link to the Original BOM, Schematic, and a new BOM provided by RJS plus the notes of this thread: https://drive.google.com/file/d/1WLyVLz20jv8eB4c_JBKH0iZbfet6My52/view?usp=sharing

I have imported RJS text file into a spread sheet, you can just import it into Mouser if you want the molex parts. There is a link in there as well for a cart already with NO molex connectors. I hate molex stuff and never use it is why :)



RJS great to see you figured it out! haven't been on here in a while but it is common to put a small piece of foam or something under input transformer cans to ensure they aren't flush with the PCB. But now you know!


Cheers!

Hi everyone,

I'm building this beautiful SA-3A and i'm reflect about the T4B, can I use 2 T4B IGS by Don audio or it's better to insert 2 matched
necessarily like the Stereo Matched Pair of Kenetek?

Thanks for your help!

Take care! :)

I went ahead and pulled the trigger on this project, since I know Mike is getting out of the DIY biz and I didn’t want to miss out on this while it was still available.

Blackdawg, for some reason, when I click your link, it only takes me to the BOM.  I don’t see the schematic or anything else.  Any chance you could share again, or we could communicate via PM to get the rest?

Thanks, looking forward to this build!

Oh man, thank you!  I can't tell you how much I appreciate it!
