it might be that philips used a common kathode resistor for the two EL84's.
It would be advisable to split this up, so that each EL84 has its own kathode resistor.
Also, replace the coupling caps from pre-amp tubes to these EL84's.
With some luck the B+ voltage will increase considerably,
giving better sound + reception.Greetings Wouter
>As per your advice I inserted two 6V4 (EZ80) rectifiers into the sockets of the Philips radio and it is now working although it is in need of a good overhaul. I noticed that one of the EL84's plate is turning red as if it is drawing to much current. I will have to look into it for my friend so that he can enjoy his radiogram. Thanks for the help Wouter and Otto.
