Philco 21 repair
#9

Update!  Have repaired all the Bakelites, but I think Filter Condenser and Mershon (which was bypassed) is wired wrong. Filter Choke (27) one end goes to 11 on Power Transformer, other to D,(goes to Field Coil), which also is where Electrolitic (31) positive connects. I'm going to change that, and wire it per schematic unless somebody tells me different.

   

Aquired a tube tester I-177, had it repaird by hainc2bc; found 3 bad tubes- the 80 and of course the two 45's.  In the market if anybody has a good deal.

   

Sneak Preview of Cabinet! Ben is almost done with it.  "Now we need a low humidity day for lacquer. Look ok to you?" I would say so, Son!

   

Here's one of the bypass condensers- they weren't too bad to 'stuff'- glued to paper carton and reuse the two end pcs.

   

Ahhh yes, the Mershon. 2" dia. x 4.63" lg. still thinking on that one.  Maybe tube cutter, and collar to fit inside.
