Preferred method to re-tension socket pins?

How do you tweak those little split, tubular sockets when re-installing tubes? My attempts using a small flat-head screwdriver seems very imprecise, potentially damaging and a PITA to boot.

Any other advice when swapping?

Thanks...

I have found that the jeweler's screwdriver method is lousy as well, for all the reasons you mention. Here's a solution I saw while perusing another tube forum which works demonstrably better - and these are great conversation pieces as well: http://www.amazon.com/DISSECTING-DISSECTION-STRAIGHT-HTI-BRAND/dp/B00M04W6NI?ie=UTF8&psc=1&redirect=true&ref_=oh_aui_detailpage_o08_s00

I like that Kentley. Thx!

I still like the jeweler's screwdriver. Just gotta get the right size, right? One I use slips in behind the finger nicely, starting at the split and them sliding it over towards the middle of the finger, and a quarter twist on each tightens them right up. Be a bit careful, and there's little or no chance of damage.

Obviously a different screwdriver for each socket type is a good thing. The hardest part of the whole job is usually finding the screwdriver needed.

I just buy belton sockets, plug in the tubes and then leave them there until they die.

Anybody tried just directly soldering the tube pins into the circuit and bypassing the socket entirely? As a recovering tube-roller, and given the lifespan of your average high-quality tube these days, I'm contemplating such . . .
