Did you have any trouble with the chroma section? Seems my 3.58 oscillator isn't running at all since there is zero color.

You will notice in the Deluxe chassis a high wattage power resistor dropper I recall either in the oscillator or chroma bandpass amp section. The power dissipation created a lot of heat which damaged the resistor it self and a coil. I repaired it by mounting a lower value resistor in its place to reduce the dissipation and mounted another power resistor elsewhere on the chassis in series to allow it to dissipate the bulk of the power without burning up anything around it.
You will see the resistor I am talking about. Check it is not open and if there are any charred components around it.
