Pye Model 19D

 This is the second example of the Pye 19 that I've acquired. There were two slightly different versions made.. the 19D and the T19D having slightly different shortwave coverages. This one, a 19D is in very good condition compared with the last one, a T19D, given to me for parts. These receivers were pretty special as domestic sets went because they had no less than six shortwave bands. These are not general purpose, but bandspread over the broadcast bands, thus making reception of distant stations much easier. Click the picture below to see the T19D.


 The rear view with the cover removed shows a clean chassis which is painted and therefore much less susceptible to rust. It looks like the tuning condenser mounting bushes are perished giving it a drunken appearance but the thing is still rigidly mounted.

 The identification plate includes the valve line-up. These are all International Octal types made by Mullard. Mullard, Philips and Pye were all related when this set was made hence the choice of valves. The use of more than one brand name meant that more sets were sold, relying on the attractiveness of each name and user's experience and loyalty of the particular brand. This was extended when, for example, Philips introduced the brand name "Stella" to their factory's output.


 The designers made it easy to adjust the set to line up with its dial, a necessary feature because of the definition of the readings due to bandspeading.


 Here's a close-up of the dial. In the 1950s amateur transmissions were mainly AM so the coverage of 80m and 40m was a useful feature.

You'll notice the mix of units maybe?... Long and Medium wavebands are shown in metres but shortwave bands in Mc/s, although the ranges are headed in the recognised units of metres. I'm not sure what M.S.W. stands for? Note it's range about 2.8Mc/s to 8Mc/s; the T19D is different, I think the "T" stands for "Trawler Band". The T19D didn't have the 13m band but had the 49m band. That band however was included in the 19D's M.S.W. band but not bandspread.

 Here's the circuit diagram which applies to both the Model 19D and the T19D. Click it to see it full size.
