Hello,

Here's a schematic.

This circuit is used in the Philips EL6435 amp.

The "+3" is the supply.

The 47 ohm resistor is connected to the feedback winding.
You can connect it to the secondary output of your transformer, i.e. the 4 ohm output. All you have to do is to adjust the value of this resistor; at maximum output the EM84 should be "closed"... Perhaps you have to build a divider with two other resistors if you use a high impedance output. Do NOT connect this at one final tube plate ! smile

greetings,
Thierry
