Just about most of it in current use.

Are they at all similar to 5534's? Sure I used them in a phono
pre-amp in the 80's, copied out of a R. A. Penfold book.

Yes, they're the dual version and about 3dB noisier although not quite
sure why.

Just thought I'd chip in (pun intended) and mention that the 5532 is
internally compensated for 0dB gain, whilst the 5534 requires external
compensation if used below 10dB gain. So the 5534 has a better G-BW product
when used at high gain than the 5532.

Oh, and the 5534 was originally called the TDA1034 and came in a TO99 metal
can.

I think I may even have a couple.
