Thanks for the info and advice!

Here's the schematic for this version of the 8G005YT.

I started to recap the electrolytic can that contains 3 caps (40, 20 and 10 uF).  I was pleased to see that the two power resistors were in good shape.  The one mounted to the chassis is a pair of 970 ohm (actually reading 1k each) and the brown one on the left is 88 ohms (reading 128 ).

So I started desoldering the leads on cap and .... grumble grumble grrrr.... rats.....

...my hand slipped as I was working one of the leads off and I broke the resistor.  
I did finally get the cap out and then thought perhaps I should have tried to take the black cardboard cover off and use the saw off the cap while still in the chassis technique....  too late now.

Does anyone know if the black cardboard around the can comes off with heating or did Zenith glue them on rather than using tar?????
