while waiting for the vert out xformer I went ahead and repalced a singe 50uf 150v cap (tested leaky). I am going to give the big can caps a chance to reform I just want to make sure it works and the CRT is ok before going thru the effort to stuff them, They are not shorted, I will monitor the current and see if they come up on the variac when I get the B+ worked out.
Tuner issues, the UHF can be tuned by turning the dial indicator no problem, but not with the tuning knob. If you push down you can fine tune the VHF, but when not pushed down it engages thru a series of gear to the UHF.
It seem that the alum gear is seized to the shaft. What I dont get is how come the UHF can still turn with that alum gear seized? My guess is there is just a friction coupling that normally works when the alum gear is not seized up. It also looks to have some kind of built in gear lash control.
I looks like I may have to remove the lashed gears on the tuner in order to get access to the screws that hold the alum gear assy to the tuner box. then I can work on getting that stuck gear off and re lubed.
