The PCB - $350usd
The chassis, for housing the PCB - $220usd
The software, to make it work - $500usd
You can get any half-decent tube tester with CRT test functionality for far less than $1000, and it comes with an enclosure! The fact you
need the software (coded in Python, no less) and it's sold separately for $500 is slimy.
Edited: HAHAHAHAHAHA! The power supply is an extra $30. What is this? Heathkit?
