Interesting HMV set- has anyone seen or got one?
I've never seen one before, and presently there's one on ebay. The set is very interesting in that it has a very compact cabinet; the tube must be very short as there's no cone sticking out thee back. Altogether a very attractive set! It's probably too old for me to take on, but I guess some of you out there may know this model and worked on them in the past. It actually looks like it could beat a few sets 30 years its junior for compactness. Although I guess there might have been some heat issues with all those valves shoehorned into such a compact cabinet. I do believe that some Sobell sets used a similar short tube, and it might have been similar to the Philco Predicta (the American set with the separate tube housing). Let me know your thoughts, recollections, etc with this set!
Cannot read the model number but the Marconi VP168 in a slightly different style cabinet but same size is shown in Radio Museum.
There was a short neck crt made available at that time, around 1960 which this set probably uses. As you say they would be a hot box, it’s AC/DC and I don’t think they would have used a capacitor dropper at that time but it’s possible.
Looks as though it may be fitted with a 700 series chassis using the short neck CME1705 CRT or similar Mullard AW43-89. I've not seen one of those in the flesh but I did have an Ultra V1780 which was also very narrow, this model and others such as the similar V1781 were made before Thorn acquired Ultra.
Its the HMV 1913 ( Date: 1960) and as John states it uses the short neck AW43-89 and the 700 series. I have the official manufacturers service manual.
"I don’t think they would have used a capacitor dropper at that time but it’s possible."
That sounds like the circuit for a modern day LED bulb!
Was something similar used in 1960 tellies?
The things that TV manufacturers had to deal with in those days like DC mains! When did we finally get rid of DC mains in this country?
Thorn 960 chassis used a capacitive dropper.
The one on eBay can’t use one with being AC/DC, I should have realised that.
There is a thread on UKVRRR on DC mains.
