In general, you can’t go wrong with a Hickok that’s tested and calibrated. Or any other brand that measures transconductance, many of which were also built by Hickok. The Amplitrex costs more because it’s likely to be better than even a vintage Hickok. For one thing, I think it tests tubes at higher plate voltages, more like actual conditions in a typical circuit.
Affordable Tube Tester
Hello all...I know there are many posts on this topic , but wanted to get a 2024 knowledge base answer ....Are any of these older tube testers on eBay worthy..? Looking for something just to test my EL34's , 12AX7, 7044/5687's for my Manley Snappers for endurance/life/shorts . Not looking to collect or be a tube seller...I've seen the one Amplitrex 1000A on Upscale ...a bit pricey..
Thanks for the help!
