Thanks for this schem.
I'm trying to get a newer 9v one of these going, looks pretty much the same overall.
I think the bipolar power supply IC is bad (U14), but I just can't read it's type. It's sm. Could someone identify the part for me please? I'm guessing a 1044 would do it, but just wanted to check. Thx!
