Was able to bend the aluminum cap slightly and get under it with the camera.. Looks to be 047 20%.. Can't tell the voltage..

Update: Found out it's rated at 400v.. I have a 600v on hand of that value and changed it out.. No difference in performance.. I can almost guarantee you the orange drop is fine..

A few notes on tuners.
Most tuners will normally tune adjacent channels if you
turn the fine tune enuf times.
Most common problem on UHF in GE's is the coax link,
they didnt solder the center pin !
You can plug a tuner subber into the UHF IF cable to test
the VHF tuner for UHF ops. When you put the set on UHF
it switches on B+ ( 12-24 VDC ) for the UHF tuner.
It also turns off the VHF osc stage & turns the RF amp &
mixer stages into two more IF stages.
Also it looks like it has a tuner cleaning pad. This should
be removed. They dry out & break up & make a mess.
Pop the cover off by light pressing of the claws on each side
of the tuner.

I used to install the cleaning pads occasionally, especially on Magnavox tuners. They were actually sold by Standard-Kolesman.
