3cx6000a7 "Tube Tester" 240v, Base, MUST BE PICKED UP LOCALLY/ CASH ON PICKUP
No wait time ready now, power supply is also capable of testing 3cx3000(2) or 4cx/3cx10,000. The power supply portion has three taps, switchable and is currently on the middle tap. If your home line voltage is 245v you will see around 6500v on the amp currently. If it is less the plate voltage will slightly decrease. This voltage is very gentle on the 3cx6000 tube. There is a line section mounted on the back.
This is a serious unit. Power supply alone weighs 300-400lb.
