Dear Friends

This particular model of Philips Does not use any Phase Inverter tube in the Push Pull output stage. The second output tube does not have any signal at the grid and it is grounded by a resistance but on the other hand is driven by the voltage from the secondary of the output transformer injected into the cathode of EL41. How this system works? Can anybody give a detailed explanation of the circuit? How the output signal voltages of the two EL41 tubes kept at the same level? What is the advantages of this circuit over the circuits where the Phase Inverter tube is used eg:ECC83.

Regards

P.Rajan
