Bush TV125 and TV125U
The video amplifier anode load resistor 10K ohm 1 watt burns out, picture and sync faults vary as to the value of the burnout resistance.
Manufacturing mod is to replace with the resistor stood out on short leads to help air flow, I replaced with a 2 watt type, must be non inductive carbon type.
Don’t overdo the lead length, just enough to clear other components.
