Default Re: Plessey PV.14E Aerial amp

The Plessey PV14 was mentioned briefly in WW 1951 November.

WW 195111 p.449 Plessey PV14 Multicoupler.pdf


It was an HF (2 to 25 MHz) aerial multicoupler with 10 outputs. It used EF91 and ECC91 valves.


The PV14B had an even briefer mention in WW 1954 October.

WW 195410 p.472 Plessey PV14B Multicoupler.pdf


This suggests, but does not confirm, that the suffix letters applied to successive iterations rather contemporaneous variants.

An advertisement in WW 1962 April suggests that aerial multicouplers were a significant product type for Plessey at the time.
