I got a Vestax 05 pro that does not turn on.
Previous owner told me it stopped working after trying using a different power supply. Maybe wrong polarity.
I got the original Power supply.
Spec says DC 15V. Output measures 22V.
I have another one exaclty the same and output on that is 19V.
I desoldered:
Q101 and the component tester indicates:

Q102 same on that one:

Diod on the board seems ok.
IC 4558D desoldered and tested with a OPA2134 dual op-amp as a test replacement (only thing I had home).
Nothing above helped.
I only get 22V voltage on the red line in the
picture. No other voltage indications.

Any ideas what to do next?
