Dunlop Rotovibe JH-4S

[GeoB]

Hallo !! I just get old Rotovibe JH-4S and I'm not sure what's polarity of power adapter.The connector is 3.5mm-1/8 inch. The newest models have 5.5/2.1mm connector. I also check the board and it's rev.B with numbers 38-89(week-year?). I don't want damage this awesome pedal just by wrong polarity.....no luck find schematics on web....Can you help, anyone??

Hi GeoB, I have the same Rotovibe and have the tantalum capacitor next to the power jack blown. Would you tell me what is the value of that one is, just read the numbers. I'll let you know about polarity as soon as I find out. Thanks.
