Hi.
I want to get the most I can get from my radio.
It is used in my mobile only.
I want to replace 2sc2078 with 2030 and make swing mod.
There is a schematic http://obrazki.elektroda.net/57_1200694763.gif , can anyone tell what to change to get this radio modded?

Sp5it,

It would help to know what Make and Model of radio you are asking about doing the EKL modification to.

That's Midland Alan 27.
Typical final/driver stage.

For swing mod I need to put electrolytic carpacitor/resistor between audio transformer and driver/final collectors. "-" towards collectors or transformer?
Must I change final to erf2030 or 2sc1969/2312 as final will do the trick?
Is there anything else to tune/replace to get it working?
Mike
