@fa-schmidt:
I'm sorry, the symbol for the NE5534 in ltspice is a bit confusing.

The opamp output (pin 6) is not connected.
The output signal is taken from one of the compensation pins of the ne5534 (pin5)

@Tangent:
A ccs with a pair of bjt would indeed easily replace the jfet one. Actually, my sims had such a ccs at first. A jfet ccs is just a bit easier to solder at half the parts (call me lazy). The jft ccs costs me 15c, the bjt one 10c (from a german supplier on ebay).
