Output Trans on 34
#5

Hi All;
Thanks Morzh, I just wanted to make sure before I did anything, that I wouldn't make anything worse than it already is..
So, yes, I can test the Transformer with my 4" PM Speaker attached to it, and see what comes out of it..
I am not going to use the Speaker that came with it, as it is in too bad a shape, the voice coil works, but the cone is torn and in very bad shape and is not attached to the Speaker frame at all..
I am going to use my Signal generator, which also has a 400 hertz Audio tone output on it and see if it is enough to make the Speaker Hum, then using the Output Transformer and then the number 19 Tube and then the Input Transformer and then the number 30 Tube driving it..
Working back ward from Speaker to antenna making sure that each section works before going any further..
Hopefully the Signal generator has enough oomph to work the Transformer to the Speaker, before wiring in the 19 Tube and so on..
THANK YOU for Your Help.. Marty
