Re: ISB Receivers
The GEC RC410 is another interesting receiver I once had.
It has switch tuning, but the switches are interconnected by a monster gearbox with Geneva-wheel mechanisms. rotate the main tuning knob by 10 steps and the next switch is incremented one step.... and so on up the chain. Big rollovers are stiff!
It has a motor driven preselector like the H2900, but its signal electronics are rather ordinary for the time lacking the high dynamic range and low phase noise efforts of the H2900. Was it one of the receivers Sosin panned? GEC-Marconi politics were not friendly, I recall hearing. I'm not sure of the timing of these sets versus when GEC owned Marconi.
