Discussioni nel forum su questo modello: Grundig Radio-: 2045WZX

Argomenti: 1 | Articoli: 2

i have studied the schematic for the grundig 2045WZX, and i noticed that the unearthed lead of the filament of the em85 magic eye tube is not connected to the 6.3 volt ac supply, but rather it is connected to one of the leads of the high voltage winding of the power transformer. i cannot believe this could be correct, as it would place a high voltage across the filament which would destroy it instantly.

my question: is the connection i refer to above correct?

i ask the question as i have recently acquired a grundig 2054WZX radio which is missing its power transformer and i plan to restore it.

regards
