Admiral 20B1 combo restoration

Another local collector recently contacted me about restoring some of his sets. I've got plenty of my own to work on, but when he told me the first he'd like working was a late 40s Admiral I agreed since I'm very familiar with them.

A further discussion revealed it's a combo TV/AM-FM/phono set with the 20B1 chassis. I have no desire to haul that beast into my place but luckily he's handy with electronics (modern anyway) and was able to pull the chassis. Better yet it was hand delivered to my doorstep Just the TV for now. I'm not even sure if he has any interest in getting the rest working.

So here it is all dusty and cadmium oxidized. I've already removed the flyback cover.


Push-pull 6K6 output should kick out some good sound.






It appears to be revision 19.


After inspecting the set, I contacted the owner to tell him it's definitely restorable. He then revealed he had actually already powered it up and got a raster. Not my recommended course of action especially when some caps have blow but now we know the critical components are OK.




The sets has fuses on both he flyback and power transformer.
