I found these and what wondering if they are any good? i threw them in my tube-03 preamp instead of the 5532s and to me i think it sounds good, but i was wondering if anyone has any more info on these. best i could find is they are similar to a lf412cn.
They're apparently dual BiFet opamps, HP-rebranded: https://4gte.com/products/hp-agilen...low-bias-high-impedance-bifet-dual-8-pin-dip/
(1826-0962 is the HP part num I believe, 8608 thus means 8th week of 1986)
Dual opamp pinout is universal fortunately.
