Any one know if the IC2 socket on the sonic frontiers SFL 1 preamp is a opamp single or duel or some other sort of IC? it is located between the v1 tube and the rear of the case. I removed it several years ago and it was put in storage , and am trying to return it to service. and cant find it
 
MC34082, found on page 4 of the PDF. An FET input op-amp. HARD to find, in my experience. However, the AD648, $6.77 ea at Mouser, is a pin-for-pin compatible part with FET input, ±18 V supply rails, very high input impedance, etc. ⋅-=≡ GoatGuy ✓ ≡=-⋅
