Philco 20 restoration.
#22

The recap is done. I did not count on it, but....there isn't much in 20 and it has tons of space.

I also added the missing rectangular can cap that should be living on the rear wall of the chassis which was missing. The 70 had exact same cap, so I re-stuffed it and now I am rid of all the old tubular caps (of which two are bad, obviously 50-s repair).
I put back the big can (I never removed the panel so the wires' soldering is original). No fish paper inside - no need.

The view on the chassis after recap
   


The big can
   



I decided to temporarily add small 1W or 1/2W resistors under the dog-bones where I had them. They either sub the open dog-bone or adjust the resistance if it is about 20% up. I did it because I intend to try to get those folks I found in NJ that carry exactly the same alumina tubes to get me some samples. If of course I get them. If not this would have to suffice.
Where I did not have dog-bones I left those old carbon ones that were there. (funny, 470K carbons are installed in 500K place and read 500K and 525K).
Again, if I am able to make the dog-bones in the future (I do have some duds so I could re-use the ends - I save them), I will put them in.

Now the tubes check and then alignment.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
