Every once in a while, you can fix a short in a tube. If the heater lights but it doesn't conduct, you can check for continuity between pins with a DMM (or if you have a capable tube tester). If you figure out which electrodes are shorted, you might be able to spot the short visually. Since the tube is already nonfunctional, you can whack it a few times in the direction you think might break the short, shifting the internals slightly, and check the short again with a DMM. Have to do this delicately - enough force to shift the internals, but not enough to shatter the tube! This doesn't always work, but it has fixed two valuable tubes in the past for me: a Sylvania 45 DHT and a Tung-Sol 5998.

Where is good place to get the TS at a reasonable price?
While it's mostly off and on on eBay, I recommend getting one from a regular trusted store while they have it. The eBay thing unless you know the seller is kind of a gamble.

You can get lucky sometimes. £40 buy it now for 2. Might not have worked but they both do and sound awesome :D

I think my favorite tube combo right now is a Tung-Sol 5998 + Sylvania VT-99 in an adapter. Really detailed, bass hits just right, and for whatever reason the VT-99 looks really cool with that little hat on it.

Very cool! Does the VT-99 require any circuitry mods to be done?
Nope, just an adapter. That said I have Speedball installed. I’ve read that you really should have that installed if you’re going to use any adapters, but I used my 6SN7 adapter before doing the upgrade and it was fine.

Actually it’s two adapters - 12AU7–>6SN7 and 6SN7–>VT-99/6F8G

An infant HeadFier might say: “adadapters” ?

You should see it when I run dual A2293s in the back and dual 6J5s up front. Looks exactly like a toddler got ahold of a bunch of tubes and slammed them into place.
