Hello !

I'm interested in finding infos about the QBL 5-3500 by Philips.

Is it possible to find it in the market ? It's an external anode

tube capable of 3000 W plate dissipation used in the past in FM

and band I TV transmitters. 

Is there any design for using it on HF ?

It is a tetrode.....and needs 800 V for the to obtain

this voltage directly from the anode ? With a resistor ?
