[Quoting 00940]The output signal is taken from one of the compensation pins of the ne5534 (pin5)
Just to clarify, fa-schmidt, doing it this way bypasses the op-amp's output stage, effectively replacing it with this more capable one. Only a few op-amps give you the ability to pull off this kind of trick. The famous AD744 is another.
[Quote]A ccs with a pair of bjt would indeed easily replace the jfet one. Actually, my sims had such a ccs at first.
Can you post a schematic? Many DIYers start with a CMoy on perfboard, then want to do a better but similar amp, still on perfboard, before moving on to one of the other projects. This would make a fine choice. I'm tempted to make a tutorial and layout for it, in fact. (It won't happen any time soon. Way too many other thing to deal with first.) |
