Question 5608a

is the 5608A double triode a gas tube ? (thyratron) i can't find a great deal of info on it just basic specs. I have found a pair from Barber Colman for use in the flame-otrol circuit, do they drive the igniter ?

The type 5608A a medium mu twin triode similar to a type 53, but with a higher plate dissipation. It is not a thyratron and contains no gas.

Thanks for the info, i wondered if it was a gas tube as there is no getter. The instructions say that the tube should be replaced when the top is cloudy or white.
most interesting !
I will try and use them.
