Tele-Tone TV149 Restoration

Decided to complete one more restoration before I close up and pack the workshop for the eventual move to a new home (yes antique TV collecting has become so addicting that I'm selling the apartment for a home with more display space ). I decided that my current favorite table top in my collection, the Tele-Tone TV149, would be my next set.
The cabinet is out at my refinishing "guy." It was in good enough shape to reamalgamate, repair, and refresh the original finish on the set. I was pretty happy to hear that the original finish could be saved, both for originality and cost savings . I'll post pictures when the cabinet returns.
The chassis was also in very good shape with no rust to be found. My first chore was to check the tubes and replace those that were bad or on the edge, 7 of them to be exact. Then I went through each resistor in the set one by one and checked for tollorance. Seventeen resistors were out of 20% spec, and a handful had more than doubled their value. After replacing all out of spec resistors with original carbon resistors I turned my attention to the electrolytic capacitors. I'm in the replace all electrolytic capacitor camp so they were all removed, insides removed, and rebuilt with modern caps. Then I rebuilt all of the paper caps in much the same way. For this set I started dipping the rebuilt paper cap in beeswax to further blur the line between original and restored. I have a thread in TV/Radio Tech Forum if you missed it.
I am pleased with the look of the work so far.

After:






You can see in that last picture that is 4 modern caps in the set. There was non-original caps in the set for these values so I did not have anything to rebuild. Bandersen was nice enough to send me 4 caps of the correct value but I was unable to rebuild them so I'll have to go on the look for 4 more .01uf 600v wax caps to rebuild.
After a nervous first time turn on (still a nail biter for me) I was greeted with sound and a raster with very little vertical deflection.



This seemed like a good place to rest and post my progress. I'll return to fight another day and tackle the deflection problem.
