Taurus 1 decay problems

The Moog Forum Taurus, Minitaur & Sirin
1

Hello, I’m Mauro Muriel from Argentina.
I’m restoring an old Taurus 1
I’m having a funcional issue with the decay function.
It does an upward glissando of the pitch during all the decay rate.

Anyone have any idea why its issue occurs?
Any suggestion how I solve it?

Thank you!
Regards

Sounds like you have contamination (flux) around the sample and hold circuit for the keyboard. Or you have a defective part in the sample and hold circuit area.
