Orange Rockerverb MK1 pre-amp tubes no power
Posted: Sat Oct 20, 2018 12:11 pm
Just got this absolute dreadfully abused Rockerverb MK1 on the testbench... 
The phase inverter tube and the powertubes are lighting up, but none of the other pre-amp tubes are starting to glow. The pots for Mid and Treble on the 2nd channel were busted, so i replaced those.
The tubesocket of the phase inverter was broken, so i replaced it. I've replaced the caps on the phase inverter. I'm seeing some heat-damage on quite a lot of parts, so the amp has been used very well (maybe a bit too well)....
All tubes have been tested and work fine, but for some reason they won't work on this pcb.... All parts have been measured with a LCR-meter and are fine... All wiring looks good...
I'm out of clues... help would be appreciated
