Zenith 9S 307 - sandbar40 - 03-26-2018

Started restoring this shutterdial Zenith starting with the chassis which has seen previous dubious repairs.
Down loaded the circuit from Nostalgia air, and can make out most component numbering, but for the two resistors in series that connect from pin 5 of the 6F6
to the negative of the first electro and transformer CT. thereĀ is no 'r' prefix, just a couple of squiggles that could be 5's.
Can anyone help here?

Hello, Looks like it's R-1=470K first one off pin 5 and R-13= 47K ohms. Hope this helps. p.s. they use M for thousands on the schematic and spell out MEGOHM for the MEG resistors.

Thanks for the info, those values make sense.
