Need technical info on BOSS PSM-5

[jrc4558]

Hi all! A friend asked me to repair a malfunctioning PSM-5. It sort of works, but the power doesnt come out of the top jack, although all the contacts are fine... (weird)
Thought I'd ask you, kind people, if anyone has any data on this pedal to help me troubleshoot it. Thanks in advance!

I have that unit, with the "manual" that came with it. What did you want to know?

Here's the specs on it:

Power: 9V DC 200mA
Current Draw: 9V DC 13mA (master switch section)
Input Impedance: 1M (send and return)
Output Impedance: AMP section: over 10K, SEND section:over 10K
Gain: Unity
Frequency Response: 10Hz-100kHz (-3dB)
Others: Effect ON/OFF is an FET switching system

And here's a troubleshooting chart for it:

Paul, is that the extent of the manual? The reason I ask is because I just got one but it didn't come with the manual.

Paul, is that the extent of the manual?

Almost. The rest of it is just how to hook it up to your amp and really basic stuff like that.

Any luck fixing it Constantin?

Finally found thi posting.

Luck yes! Its fixed and returned to its owner. The problem was the physical deterioration of one of the jacks. And i thought its electronics...
