I thought the ROE's would be a liability.... I could just change all the capacitors eventually...

I'll check for a short on the capacitor. I do have a capacitor tester if that will work on the same place?

I had a read up on the service manual and it looks like in order to remove the board, I will need to discharge the EHT etc and then remove the board.

Also, after I've energised the circuits, how long does it take for the HT to discharge or is there an easy place I can measure for it and discharge if needed?

Looking at the schematic, how would a short on C306 load down the 115V supply? Maybe its a dumb question...?
