The German collection

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.

The Russians are leaving

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

Valve list ordering

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.

ex-exhibits

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.

Farewell to some monsters…

After many years the RD150YB, my huge and heavy transmitting triode, and the 150/6G Mercury Arc Rectifier are destined for a new home. As part of my shrinking of the collection, these two have really got to go. It will be a shame to part with them, but then over the years they have just sat in the corner of the garage, the triode in its huge crate and the MAR on a shelf above, covered by a door for safety purposes. If I ever need to move the collection, these two would be left behind. I am keeping the CATs, so I still have the CAT10 but as that has had an abusive life I don’t mind transporting it on its side – the RD150YB has spent its life sitting upright in its crate and needs to remain so such that the filament and grid assembly does not bend under their own weight.

So, if you want to see the pics of these two, hurry as those will be removed once the valves leave here.

Recently some other old favourites departed here, including the MT9L and SAL-39 and TAL12/35. All have gone to new, caring homes!
