Dumont RA-103 Project Redux

[Chris K]

Hi Folks,
I'll be restarting this one again. I got a NOS delay relay installed and working Last power up, I had smoke from the area of the vertical output transformer. After much analysis revealing the value of a VTVM in testing coil winding integrity, I found no damage to the VOT. This doesn't mean I'm certain this was the source of the smoke...just that it was coming from this area. I sourced a new 1Kohm focus rheostat from Surplus Sales. I'm going to install it on the back of the chassis as the shaft is not long enough for a direct replacement. Tom C. gave me some advice on extending this but I can't remember what he said and I'm too lazy to search for it!!!! So I'll be on a journey through this in the next few months and I hope you will be along there for the ride. Just wanted to get things started!
