I can’t believe I’ve not updated this site since last year! Well I now have 4 boxes of CV valves to sort out, including a CV2, my lowest number. A lot of valves have left the workshop – basically for free as there is so little interest and as I said before I am no longer engaging with eBay (the money is not worth the hassle). 8 large boxes of them and several smaller boxes filled a car. There are a lot left which will be listed here under Sales at some time and what does not sell will go to auction. If you see anything on the site that is definitely not CV marked then it will b for sale, except a few cases. I am even considering letting the REL valves and the 1B series go now. Most of the Germans are sold or are spoken for as are one or two of the Russian radar CRT-types. Anyway, none of those are listed as exhibits now.
I’ve not updated the collection for ages. There is a CV magnetron sat on my desk waiting for me to take pics, as well as a couple of fuze valves that people kindly sent me. Being realistic I am not going to get close until October this year because I am trying to complete the corrections to my Ph.D. and running out of time. So everything is on hold.
I also have 4 boxes of CV valves 300 miles away waiting for transport. uShip came up empty with really stupid prices so these may end up going by courier or me meeting halfway. Time is against me.
I also have half the workshop full of valves for disposal. Since I gave up with eBay and PayPal moving these has become difficult. That plus the complete lack of time anyway. I hope to go to a sale later this year which will hopefully reduce the stock somewhat. Some are ex-collection but most are mundane valves.
I have been trimming the collection for some time now and disposing of valves which helps maintain this virtual museum and also reduces the amount of storage space needed. It also helped me finally focus on what I want to collect, rather than just anything and everything.
But someone mentioned to me a whole back that people may still want to see these. As the main pages only display what I actually own, once removed a valve’s web page is removed too.
So I have been making PDFs of the more unusual valves as I remove them and these are now held at http://vacuumtube.info/oldvalves/ – it is simply an automatically generated list of PDF documents, each one of which is basically the valve page saved as a PDF via Safari.
My thinning of the German collection is under way with some having gone onto my disposals page and others onto eBay or into a crate ready for the next local sale in November. This section of the collection can be seen here. Not all of the valves will go, the two Gema valves and the RD4Ma for example will most likely be staying here.
After a lot of thought I have decided that the Russian valves in the collection are to go. There are some quite fascinating types there, and thousands that I don’t have. While I have a few I’ll always want others and this is no longer the way I plan to expand my collection.
The collection of old had four themes: CV and military stuff; German; Russian; and then everything else. I got over the ‘everything else’ business a while ago when I originally decided to concentrate more on CV and British military types. But I carried on expanding the Russian and German collections. I will find some way to preserve the more interesting or unusual pages somewhere before I remove them from the website.
I am undecided about the German valves but I suspect these will also go. Some are quite rare. Any Russian / German valve collectors out there?
The Russians are now all removed and the Germans can be seen here
Deleting valves finally broke the random image display that appears down the left of the home page. That was a rather old script I wrote that had 32 images pre-defined and selected a sequence of 5. So I’ve re-written the script. It now dips into the valve database and generates 5 random images from any of the valves. Pity some thumbnails are rather fat!
No prizes for getting 5 valves all the same… it should always generate 5 but there are one or two bogus lines in the database still so you may get less, and I’ve left it to chance whether you end up with more than one the same!
Moving the valves out of the roof space and into proper storage boxes gives me a chance to re-do the pictures of some of the older exhibits. So, CV378, CV430, CV1934 and CV5008 have had a makeover. Also, the CX1140 was destined to be removed but I can see a faint CV marking on that concurs with what it should be. So it’s been renamed CV8563 and tidied up. The CV number is written on the base in ink but I had not looked over it carefully to see if there was a trace of the actual mark, and there is.
I finally got round to ordering the valve list such that searches come out in a better order, for example searching on cv*. In a way it’s a bit of a cheat because to do in in SQL was getting very complicated and so I wrote a script which orders the index and writes an index number which SQL then sorts on.
It’s not perfect – valves which being CVX end up at the end of the CV list rather than where they should be numerically – but it’s a lot better than it was.
Someone asked me if I could have a section for valves which I have disposed of. I am not yet sure what the best way to do this would be because once a valve goes it’s database entry goes which wipes it from the website. This website has always been about my physical collection, not just a set of photos. (well, ok, it is really just a set of photos but you know what I mean)
Saving images of ex-valves is straightforward but it would just be a pile of pictures, no index or text. I have experimented with converting web pages to PDFs so I only need to store the one file. Other than that I’m not sure what method will fit with the overall site yet.
On the plus side, once I trim the current collection to just the CVs and military types as planned there should then be no further deletions.
For many years the majority of my valves have been stored up in our roof space and I had no idea where anything was. Finally, a few months ago I decided to buy some large plastic storage bins off ebay – 12 of them – and begin to store the valves more properly in the garage.
I am now up to 24 of these bins with 19 full and 714 valves to go. Not all of those will go into the bins as the larger ones will just go onto or under the shelving.
So hopefully in a couple of months time all the valves will be out of the roof space and stored where I can find them. Woo. This has only taken me forever…
