Finally found the time to finish this phaser. Replaced the electrolytics,  adjusted bias for the fets and it sounds as good as new. I really like the off board wiring done to it. Shielded wires for everything in the signal path. 

The opamps have sanded but they are all seem to be LM1458:s. 

The bypass switch is a nice, non-clickinging type. Never encountered them before. It’s not wired for true bypass.

The pedal works of a 9VDC battery but also have a DC jack, though the circuit uses +/- 4,5VDC from the power source so it can’t be daisy chained.

Got hold of this old phaser in a no working contition.

Tried to power it up but  found that it’s short circuited. The problem was not located in the circuitboard, found that one of those blue old tantalum caps on the power inlet for the DC-jack was  shorted.

I had them replaced and yes! There’s phasing. However it seems that it’s in need some more tending to, it’s way to noisy.  Lets see what a total recaping can do for that.

To be continued….
