• Anotaciones
• The Globe model DuoDyne 770 has two primary tuning control knobs plus 4 additional knobs and two Jack sockets. An original add shows only one Jack socket. See also the other variants of model 770 - with and without the name DuoDyne - and with either upper row with 5 knobs, missing the left knob on the lower part - or having two small knobs on each, the lower and the upper row. We try to find out the different variants and then to put them into the right time sequence. See for instance the numbers on the two small knobs on the upper row - on one of the variants.Be careful to which variant of the 770 you load photos. Tell us please by placing a forum article to the model if you found an other variant we don't display yet - and we will split the model then.
  This variant has 4 kobs on the upper row (not 5) and only one below in the middle. As also the adds show, no characters engraved on the outer (small) knobs. It shows a plate in the center. The add shows only one Jack socket but are there existing models with only one Jack socket and are different knob forms original or not?
