As in a previous message with the reflector copied, the discussion about the
heat sinks got me to wondering if it were possible to use the GS-35b heat sink
on the GS-31b. From the photos that I received it looks like an adapter would
have to be made. Considering the relatively low cost, it wouldn't be that
expensive to see. If it works fine! If it doesn't then the low cost would be
worth the experience.

I don't think the hole is tapered. I've seen loads of these things around at
Eurpoean fleamarkets over the years, but never took that much notice of the
tube geometry so I could be wrong. I'm pretty sure it's just an interference
fit with the threaded nut to hold it in. However that's a bit
counter-intuitive to my thinking: wouldn't a taper be better from a heat
transfer point of view since it's more likely to get a good surface contact all
the way down? However these things were built to a price in the old Soviet
Union where design simplicity* (and tooling simplicity*) was a big criterion so
if it's not tapered I'd be tempted to put a load of heat sink splodge between
tube and heatsink (unless it's already there)?
* I like simplicity. Simplicity is *GOOD* and comes right after Godliness and
cleanliness in my book :-)
