Recommend tube matching device

[braintheory]

Apologies for the newbish question: what device can you guys recommend I get to check on matching my powertubes. I’d rather have a device to use to check them than using my amps. I’d use it for EL34’s, 6L6’s, 5881’s, 6550’s, KT90’s, KT88’s, KT77’s, and KT66’s. Hopefully something not too expensive if possible, but still does a good job

Sorry, go fish.

Last one I knew of was the Orange VT1000, and I think it's been discontinued.

Not cheap though...
