> about how matched are the fets in these 4069, does anyone
Haven't tried the 4069, but the FETs in the 4007 are matched well
enough to act as VC resistors in the mono compressor / stereo
expander circuit of the ARP Quadra's phaser.
Interesting combination, btw: They used the BE resistance of bipolar
arrays for the all pass stages, but the DS resistance of mosfets
for the compander circuit.
