I'm going to design myself a vari-mu that is based on the idea of a 670 (meaning a vari-mu stage and a separate power amplifier driving a rectifier), going to be a long route I'd imagine..
Anyhow, I wanted to stock up on PCC189's and this came up:
http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=150222347177
54 Tungsram PCC189's in-a-box.
I'd imagine such a box would contain tubes that were manufactured pretty much at the same time, unless someone has messed with the box.
In any case, this is about the safest bet you can take to find good matches. Some 3,00€ a tube isn't a bad price either.
