No damping diode on some (not on Gem). The emitter resistor 510 to 680 probably depending on supply. The table model Decca uses two spring top 6V 996 packs to give -6v for speaker. The Gem uses a 6V VT50 pack (mine has 4x AA inside).
The Gem (1958?) is same case as the earlier valve model (1957?*), so both have ferrite rod in pop-up handle. The earlier one tunes the LW, but the Gem simply has a Light Program presets for LW via a switch (TC1 & TC4).
I might be misrembering. They might be 1959 and 1958. Huge IFTs, but single tuned. The earlier valve model is all double tuned twin core IFTs, so only needs one IF amp (DF96). The Vagabond CN439. I have both and the amazing Vanguard VHF/MW/LW portable, maybe 1957? It has no DK96. All DF97s.
