Technical Information

Valves (8 + magic eye):

Frequency Bands: 2

Chassis Notes(most schematics can be clicked to download a full size version) Appears to be an 8-valve + magic eye chassis - rimlock valves and octal rectifier?  Probably 6X5.  Eye could be an EM34.  Later model IF transformers.  No ARTS&P label visible, so chassis date could be towards the end of that regime.
