Default Re: Bush VHF 81 Restoration

I've attached a photograph of the dropper resistor. Since there is no A or B markings I cannot tell which voltage it is set for.

R34's value has increased by 18.5%. Its tolerance is 10%.
R36's value has increased by 21.5%. Its tolerance is 5%.

To check the health of the UY85 would it be a good idea to desolder the wire on pin three and measure the HT directly on the pin? Since there will little current draw I expect the HT to be higher than normal.
