RCA AR77E. Another classic comms. receiver from RCA.
Frequently referred to as "an AR88 ~ but with bandspread".
As with the RCA AR80, not a commonly-found model, but as with the AR80, you can see the distinctive RCA styling, viz. the famous & well-known AR88.

RCA model AR80.
A rarely found comms. receiver from RCA. I've never seen one 'in the flesh', but do have some documentation about this receiver.
You can see the distinctive RCA style that becomes so predominant in the later AR88.

Marconi B28 (Naval version of the CR.100).
Classic design: 2 stages of RF amplification; single conversion s/het.; variable selectivity with switchable crystal filter for C.W.
The hole in the front panel, top right, is where a signal would have been injected for Radar Interference Suppression - R.I.S. The degree of the suppression could be adjusted by the knob labelled "R.I.S."
The CR100 / B.28 saw extensive service during WW2.
N.B. Many CR.100/B28 receivers are seen with an S-meter. None of these receivers were ever built with an S-meter as standard fitment - or so I have been led to believe.

The RCA AR88D. Extensively used during WW2 in many roles.
Classic configuration: single conversion s/het. with 2 RF stages and variable selectivity. IF 455 kc/s with crystal filter. Big, heavy - and beautiful! :like:

When received this set did not work. As can be seen on the right, the 0.05uF RF capacitor has given up the ghost. The tone corrector capacitor, just under the Paxolin voltage selector board, had also got very hot and the wax has melted out of the ends. Unfortunately, the 50+20 main smoothing can didn't want to reform so was 're-stuffed'with 22 and 47uF electrolytics. Quite an easy set to work on but with the previso that it is 'live chassis'.

That's a very swish example :)
Mine's in the attic at the moment. Unfortunately I can only have a limited number 'out' at a time. There's a PE60 up there as well, another of Pye's more eccentric sets.
