forgot otl with few tubes

otl run if many tubes are used

because you need high current and low output resistance with low feedback

easy to build something around a window comparator that after LP filtering checks the DC voltage and switch of B+ in the event of failure.

Hans can you elaborate on this a little please?
Do you have a schematic?
