  Nel funzionamento in CA inoltre, le valvole sono alimentate in CC tramite un "raddrizzatore ad ossido" che alimenta anche un batteria "tampone".

  Lo schema e quindi l'elenco valvole indicano diverse incongruenze. 1AL6: Sembrerebbe inesistente. 1LC5 (Loctal) oppure 1A7 - DK21 (Octal). Nessuna delle 3 è compatibile. 3Q4 oppure 3S4 (non perfettamente compatibili). UY42 oppure EZ2A. Assolutamente non compatibili. Non si sa quindi quale delle combinazioni sia stata effettivamente utilizzata.

  The schematic indicates several inconsistencies:

  • 1AL6: seems non-existent
  • 1LC5 (Loctal) or 1A7 or DK21 (Octal): none of the 3 are compatible
  • 3Q4 or 3S4: not perfectly compatible
  • UY42 or EZ2A : not compatible

  It is unknown which of the combinations was really used.
