II know I am winding everyone up by posting this. But the set has I expect past 400 hours. In my pandemic office at home where I work, I have been runni g the set about six hours a day. CHCH-TV runs old sixties,/ seventies shows all day.

I had the set apart at about 350 hours to check the electrolytics. The two I tested (rectifier output) leakage was about 400uA at full rated voltage which is normal.

The only electrolytic which was bad was a tubular axial mount 25uF at the audio output supply. This,was replaced as it failed my original test. All others have remained original. And about half of the original paper capacitors I left if they were in the circuit shunted by a resistance of 100k ohm or lower. All the other paper capacitors have been changed.

A couple of resistors,were changed as they were out of tolerance and affected performance.

Here,are so.e snapshots from this afternoon oat via an RCA ATSC set top box.
