Hi all,
I just put filament voltage to my new 8169 tube for a
little burn in time.
To my surprise, the filament appears to drawing about 48
or 49 amps instead of the data sheet 42 amps with 9.00
volts at the socket.
Should I be concerned? Could this be the norm for a new
tube, then after a few hours, it will drop back to the
42 amps?
Any informed insight would be greatly appreciated.
