If anyone happens to have the schematic, values, ohms and watts, of R801 and
R802 , for the 24V rail would be nice.

Protection circuit relay fails to click over, because no 24V rail.
I was told someone has previously had a look. R801 and R802 are droppers in
series from the 44V main rail down to a 24V rail TO220 pass transistor.
R801 looks genuine 1R 1/2W, but R802 has the wrong lead bending (none) and
different colour banding structure to other Rs on board and measures 4.7K,
1/3W which makes no sense and just a couple of volts at the pass transistor.

Replacing 4.7K with 220R the 24V relay clicks over etc
Dropped voltage at the 2SC4883 is 32V for first few seconds then drops to
24.8V on big relay activation. So about 1.8W dropped over "R802"
"24V" rail drops from 23.2V to 22.8V

Going down to 110R then 37.1V to 32.8V and "24V" from 23.7V to 23.6V. About
1.1W dropped over "R802"

Assuming the original was yellow green something what was the likely value
resistance and wattage of presumably fusible resistor in series with the 1
ohm ? 0.47R, 4.7R, 47R ?
A lot of the red and orange colour bands on other resistors have faded to
brown and silver/gold bands have faded to feint
