• Notes

• Color: brown. Also called simply 511 (w/o A). Similar to A-512 (ivory). Similar to CBS Columbia model 511. Same case as Air King 4705 (1946). Riders shows a dial lamp, Beitman (CBS) shows no dial lamp. Both schematics list 12SK7 not 12BA6.
  But a back label lists a 12BA6 in contradiction to the really used 12SK7.

  Cabinet : painted bakelite.
