Thankyou Audioguru for the reply.
Surely F6 need a high voltage that is why a transformer (my profile pic) sits before these tubes. You know, rectifying or repairing a thing all by yourself always gives a great pleasure. What my idea is that can I some how get a led usable voltage from the primaries of this transformer before it is stepped up... although I am not fully aware of this transformer's primaries, secondaries etc because it has some 7 or so pins....
