Ok for starters only use plastic or FG tools working around HV cage.

You prob blew the damper, Try a new damper tube.

By blown you mean the filament is blown? Because it still lights.

Set off

Remove the horz out tube from the socket.

disconnect the plate lead from the tube.

put a DC volt meter on the plate lead (+) and the neg to chassis.

Set on should be about 400vdc

First time I got only 17 volts then all my other attempts were zero

ok now just trace back until you find the 400v

look for burned coils if nothing at the pin 5 of the damper

also make sure you still have B+, if the damper was shorted you may have blown the B+ fuse again.

use the correct fueses.

There is a power supply fuse that I mentioned that is blown and I am guessing that MAY be the problem..

if the fuse is blown then that is the problem.
Get the correct fuse put a good damper in and try again.

Got the HV back and was able to acquire a leader lcg-400 fully working for $60. Now I feel as my horizontal and vertical hold have gotten worse with the patterns displayed even though I have recapped both the vertical and the horizontal board... I am also getting barber polling when I turn the color knob all the way up and fine tune. What is wrong here? Do I need to recap the boards or should I recap the main chassis? Here are the pictures http://i.imgur.com/iZtVJZt.jpg http://i.imgur.com/M9VCUjn.jpg http://i.imgur.com/fOMxSXN.jpg

Looks like there still could be issues with the vertical.. As for the swirlyness in certain areas of the pic, that could possibly be the Leader pattern generator.. Those things usually need to be recapped to function properly.. I have one also that's a bit touchy.. The convergence is off quite a bit I see..
