• Notes
• Radolek-Catalog mentions as first tube a 6J6G. This must be an error, since the 6J6 (=ECC91) did not exist at that time, and a G-version is nonsense, since all 7-pin miniature tubes were all-glass types. Most probably a 6d6 was employed for the RF stage, being a variable-mu tabe, suitable for AGC.
