A couple of CRTs ideal for SSTV
Posted: Sat Mar 25, 2017 8:46 pm
G'day all. I've accumulated a bit of a collection of CRTs over time and a few of them are long persistence good for SSTV. I was talking to Harry about them as he's playing around with SSTV lately and he suggested I share them to this forum so here's some photos of my long persistence CRTs.
The first one is a Philips DP7/32 which came from an Australian made cardiotrace ratescope heart rate monitor that was recently given to me. I read they are very rare so am lucky to have one .
The second one is a very large VCR140 magnetic deflection radar CRT, I actually have two of them, I got them tubes with a late 1940s American Andrea T-VJ12 B&W television chassis http://troysvintagevideo.0catch.com/andrea.html , believe it or not those tubes were used with this set, this set and the tubes were probably used television training courses in Australia in the early 50s leading up to the introduction of television. Anyhow this tube has a different number inscribed on it which I can't find on Google but it should be a VCR140 equivalent.
Anyways those are my tubes. I do intend on building a SSTV somewhere down the line, will start with making a small one with the DP7 and later on a large one with the VCR140.
