All,

I have mad it to page 64.  When I check the volts at R30 using my DMM I get
8 volts. I assume that the left side of R30 would be having the front of the
radio facing me so the lead I tested was towards adjacent the side panel. 
It did drop to 7.5v but at that reading the L30 was at what appeared to be
it's maximum travel limit toward the top of the can.

I searched the reflector and have found that I have 4.0 volts at U6 pin 5. 
I have 16 turns of red and 4 turns of green wire on T5.  When I decrease the
frequency from 4000kHz the voltage does drop.

Also I bought the toroid's pre wound since my eye sight is not as it used to
be.

So where should i go from here?
