After 8.5 years of study, including several breaks on medical grounds, and a final mad dash since last friday I finally found out today I am on the pass list and will graduate with a Ph.D. in law next month. That’s the single most intensive thing taking up all my time these past years. Well, that and the kids!
So, I finally have some time to turn my attention to my greatly ignored valve collection. And I have come to a decision. I’ve been swinging between wanting to sell the whole collection and wanting to keep on expanding it. In fits and starts I pulled out a lot of non-CV and non-military valves, many of which went on eBay until their Global Shredding Programme messed things up and I quit.
But in order to further trim the collection I have decided to strip out everything that is not actually CV marked, bar a few specials like the RELs and some of the 1B series. So, up for grabs will be all the UK military stuff that is not CV marked. Bearing in mind eBay is not really an option now I am open to offers on any or all. Do get in touch if you are interested in any.
There are a few oddments which are not up for grabs, like the parametric amplifier tube, and the REL stuff as I mentioned. But equally there is some very interesting, and in some cases old stuff in the collection which will be available.
I’ve no idea if anyone even reads these posts and so I will also be offering some around where I know there is interest. So be quick!
My little Canon snapper is no longer up to the task. The flash does no justice to larger, or dark valves like the two I added recently. I suspect it’s time to build a light box.
For some time I had a CV1931 on the website, the example being a 6H6 metal double diode, though not 6H6 marked. Today I got a glass CV1931, also marked 6H6GT. I never checked before but the metal one is clearly incorrectly marked.
The CV Register has three CVs in a series: CV1929 / 6H6G, CV1930 / 6H6 and CV1931 / 6H6GT. This makes sense.
For now I’ve left the page as-was but added the glass valve.
The CV5403 page has been updated because the TWT came with a test results sheet with more data that I had available from the EEV catalogue.
I’ve had an interest in amateur radio since I was young. I’ve had all sorts of radios, built radios, wired all manner of aerial but never got round to taking the exam. Then the exam changed from the old class-B / class-A business to the new foundation/intermediate/advanced. Still I never took the exam.
Then I got interested and decided I would. So I wanted to find out where I could take the foundation exam. I contacted a large society and got nowhere. I tried the local clubs and never got an answer. So I gave up.
I just decided to look again. Apparently the nearest clubs where I might take the exam are at least 10 miles away and meet on evenings when I am busy. One club has a calendar, the latest event in which is some time back in 2013.
So I won’t bother…
