Altec 436A variant
« on: July 21, 2005, 03:27:20 PM »
I have a friend's clean, unmodified (for now!) Altec 436A on the bench and I noticed that its circuit varies a bit from the schematic that's on the Recordist website. I believe the unit I have here is an older version. In the interest of adding to the general knowledge base, I've altered the schematic to match this version. Grab it for your collections.

I need to raise this one from the dead.

I have an old Altec 436a on the bench, but it doesn't match the readily available schematic. NYD's old photo schematic above is a dead link.

Does anyone have this variant schematic on hand?

Whether you think you can or you think you can't, you're probably right.

Reattached schematic above. Was getting 404.

This is not the one either. But I was able to find it buried within another thread.

Thanks!

I'd be interested to see the one you're working from. So it's a 436A, but a factory variant that's different from the one above?

Here is the version I was working with. Notice, it does not have the center tapped input transformer.
