I've been asking in a couple of places already, apologies to those of you that have seen this before.
Over the last year, I've been putting together a nice 'frankenscope' using a Wild M20 base, Wild Aplanatic-Achromatic condenser, Leitz Heine condenser (found one for $20!) and Nikon CF objectives (4x & 10x & 40x E plan, 20x CFN plan, 40x CFN plan phase) +a Lomo water immersion 70x 1.23 phase objective.
However, there is one critical part missing: a phototube.
Ideally, I want to find the HU phototube with the three-position switch. But I could probably live with the H version with a fixed 25%/75% beam splitter (but the Heine eats so much light I'd prefer the HU one!).
I've been burned a couple of times recently buying things from US surplus sellers on eBay, and those mistakes get really expensive when you're located in Europe. So I would much rather buy from someone here.
So: is there anyone out there with a nice, clean Wild M20 photo tube that they are willing to give up for a fair price?
Wanted: Wild HU photo tube for Wild M20.

Well, I emailed an offer of $150 for the HU phototube that's been sitting on eBay for a while with a $269 price tag. The seller accepted, and confirmed that it was in "excellent optical condition", so hopefully I can get the money back if it's not. It'll cost me a bit more than I'd like with shipping and taxes, but I can live with that if it works. Hopefully I'm set now.
