Anyone Here Ever Purchased A Tube Tester?

I had one briefly that had three more knobs than the space station cockpit. I sold it to somebody hopefully smarter and more committed than me, which would not have been hard..,

When I started playing with 4 pin DHT and rectifiers I bought a Hickok 800.   It looks like it should be in a museum, it's that nice.  It was serviced not too long ago and have saved me from using a bad tubemore that once.  It paid for itself by not allowing tubes to damage my gear.   

I use a cheap vintage tester, Superior TD65 purchased on eBay and it gives me what I need to know and works fine. I highly suggest anyone with tube gear get one. It doesn’t have to be a very expensive one, but one that will tell you if a tube is bad, weak, or not. 

Transcendental Sound used to sell a kit which I built and have been using for several decades. I can't imagine living without it.

@larryi I'm jealous. Been wanting the Amplitrex for a while now. Certainly the best currently available.

AMPLITREX AT1000

I bought a Beck Elektroakustik RM-1 tube tester in 2015. It was customized for the main tube types I use in my system. It works well and the support is good. However it does not test the tubes for background noise.
