Basically this is a Pye D16T in disguise - and not a particularly good disguise with the only additions being the three horizontal wood pices over the speaker grill and a discrete "Invicta" logo on the bakelite cover below the screen.
This set is a key post-war design. When television resumed in June 1946, resources were scarce and what resources there were the Government were keen to see used for export - Britain was bankrupt and home luxury items were faced with a cripling high purchase tax. The few TV manufacturers able to supply any sets managed little more than to build what were basically their pre-war models. But Pye had been developing their television technolgy since before the war had ended and their results were the only truely new design then available. Significantly more compact than pre-war sets, the picture and general stability of operation was streets ahead of pre-war sets too.
But television design was progressing at a fast rate. It is interesting to compare this set with it's later replacement, the Pye D18T. The later set was the first set British set capable of running from both AC or DC mains, thus dispensing with the heavy and bulky a mains transformer. The D18T's screen and cabinet size is the same as this TL31's, but these developments resulted in a set that is significantly lighter.
|SERVICE DATA||Yep, 'tis same as the Pye B16T/Pye D16T and can be downloaded from the Pye page.|
|CURRENT STATE||It's all there, theres no worm, but needs full restoration. Just like every example of the TL31 and pye versions I've ever seen, the control knobs went all distorted and just plain funny, so for now the set is wearing some controls of a Pye radio.|
|WHERE I GOT IT||Bought privately for 800 drinking vouchers.|
|The pretty EF50s are buried under two metal plates presumably intended to try and kee the EF50's located in their wobbly sockets.||The power supply chassis dominated by a real monster of a
mains transformer which is also responsible for generating the "widow-maker"
I hope the stupid wire-across-the-mains-fuse isn't responsible for the wax starting to melt out of the mains transformer :-(
