Kk sir,
Thanks for remind me.....
It is rail to rail +12.38 &-12.38, mean total diffrences 24.77V at V+ when refer to V- .
so it is +12.38,0,-12.38-->total 24.77V difference.
Since i put probe at point V+ (pin 8) & point V- (pin 4)
Dear KK sir,
from your experience, which OPA is suit to replace the TL072 in this 8000A.
(i wish to increase slightly clear, natural & stronger but good control of bass, warmer vocal in 8000A)
In my mind got 3 choice --> 1) AD 8066 (since it's bass better than opa2132/34 2)OPA 2132/34 3) AD 8620 (i worry this too agresive)
i know most people will suggest opa627 : ) but this it is expensive in malaysia at least 2x-3x the price as the item 1,2,3 above. And main issue is taht i don't know how to build the circuit to pair up the opa627 with coupling cap : (
ahrader,
had check, octave sell AD8066 at rm85 (include the panel, BG cap), farnell sell TI opa2132 (dip) at ~rm25.
TL071 is single channel, u may just get a opa 627 (dip) ....since it can support +/-15v (typ)-->total=30v |
