P-QOPAMPDDOp-Amp - Orange, Dual Discrete, Low-Noise, 8-Pin DIP

The Dual Discrete op-amp is specially designed for audio and is among the most musical sounding dual discrete op-amps out there. It is available in DIP 8 format and can be used in any CD player, DAC, or preamplifier that currently runs DIP 8 based IC dual op-amp types. The overall soundstage and transient detail will be greatly improved when used in pretty much all audio equipment that it can physically be fitted to. It has a very low noise Jfet front end so it can run with input impedances above 1M Ohms if needed. It can replace the following, provided the equipment it’s being used in has 22mm of height clearance and 5mm side clearance (per side).



  • OPA2604
  • OPA2134
  • TL072
  • NE5532
  • LM4562
  • OP275
  • OP285


Please check that the PSU can supply the extra current needed, especially if replacing more than one existing IC op-amp with our op-amp as with all discrete types, they do draw more current.

P-Q1N474XDiode - Zener, 1W, 1N4741A, 1N4748A

A semiconductor device that, above a certain reverse voltage(the zener value) has a sudden rise in current. If forward biased, the diode is an ordinary rectifier. When reverse biased, it exhibits a sharp break in its current-voltage graph. Voltage across the diode remains essentially constant for any further increase of reverse current.
