Putting It Back into Service.
This was done on and off over a span of years and was completed Dec 7, 2017.My version, some components looked like those shown here but there were others that were really different.
As can be seen, for the most part I removed all the paper capacitors and put modern ones in. I only restuffed the parts on the chassis top side.
Changing Position of the Modulator Acorn Tube
Upside down or right side up?
Conclusion:
Rather inconvenient for servicing but better than nothing to check severity of horizontal and vertical linearity settings on the TV. Still worth keeping in my collection because of how odd ball the components are and the influence of World War 2 on the post war growth of electronics. It is an example of the challenges of restoration of vintage equipment.------------------------------------------------------------------
