[Amps] GS-35b heat sink

[Glen Zook]

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 :-)
