What do you mean, "IF chain"? The ground connections are good. What I'm wondering is if I followed the instructions the way I interpreted them. this is what they say about the first step listed....

Use a .1mfd cap on the high side to pin 6 of the 7A8 tube. Low side to B-. Set generator to 455KC and output meter across voice coil.

I did all that except used a .001 cap.

Then, it says to adjust A1, A2, A3, A4.

Remarks column say to turn A3 completely clockwise. Then adjust A1 thru A4 in order given, for maximum output.

I did that except after turning A3 clockwise, I adjusted A1, A2 and then figured A3 followed by A4 to be adjusted for maximum output. I'm wondering now if the meant to leave A3 clockwise and just adjust A1, A2 and A4 for max output. Just an afterthought.
