HF tunning

[Bob Meyer]

I have no way to make 2 tone audio.
I do use audio osc. tube type heath kit.
at about 1 KHZ. use MOD meter to set 99%.
I do have a heath kit scope and 
set AM mod just under clipping.
which was AM limmiter in rigs.

My RCI 2950 has DX 100 mod on back.
works great for driving tube amps.
I have heath kit ? 101 with 2 6146 tubes.
It is put away right now and doen't rember number.
Also have a collins rig.need tubes and caps but
thats a outher project when I get the money.
The heath kit DX 60 tunes different on AM than HF tube amps.
Again thank you for input on AM tunning tips..
I did not think of tunning for a dip in plate current.
This works well I just tryied it.only a small drop in power.
This should run coller.
