Re: Stella ST1007U
Summary of work done so far: The chassis has been removed from the cabinet and the CRT taken out and stored in a safe place.
The old HT smoothing capacitor removed and the replacement test fitted on the chassis. It's going to be a difficult task drilling the holes for the condenser clip and it might be much easier simply to solder it in place.
The replacement smoothing capacitor was fitted on Saturday evening along with the 10mfd electrolytic capacitor (C76) connected between the screen grid and cathode of the EF80 video amplifier
The smoothing capacitor has been reformed and there is now a steady 230volts across the HT rail. That's slightly higher than the working voltage. It's time to refit the CRT and test the set.
A new CRT securing band will be made, the attachment shows the condition of the original part, it's rusty and liable to break anytime.
DFWB.
