Update: Technics SA-222 Stereo Part Number

[Brad]

Hi,

Thanks to everyone for your suggestions. I found the part number
for this IC, # SVINJM4559DD. NTE 778A is a replacement, which I
did not have, but I used a LM1458 and this fixed the problem.

1458 is a first generation dual(quad) opamp. I'm glad it works, but there
are much better chips out there. Even the venerable 4558 was better IIRC.
