Discrete 2N4403 from 1976, same noise performance in Moving Magnet RIAA preamp, as NE5534A. And better performance than the dual (5532A)

A followup regarding TI NE5532 and NE5534 availability. Both devices are now back in production and are available in DIP.

The OPA2134 has also returned. The move to 300 mm appears complete.

Pn2222A and PN2907A also drive class d very well too.
These are also good low noise choices

Well colour me surprised!! The threads that relate to the demise of the NE5534A were clearly premature. Mouser have nearly 16,000 NE5534AP DIP in stock and 10,000 NE5532AP in stock.

Although not the correct device for phono (although it is only 1.4dB worse in SNR as compared with the 5534), the NE5532 is interesting (apart from being a dual) because the maximum rail voltage is +/-22V, whereas most other audio opamps are +/-18V max.
