[R-390] Z702 Adjustments

[n4buq at knology.net]

In light of the recent discussions of PTO output, it was mentioned that 
some PTOs have a slug-tuned T701 and others do not (case in point, the 
Cosmos PTOs).

For those of you that do have a slug-tuned T701, where is the adjustment 
seen?  I have looked on the WEB for pictures of various PTOs and all I've 
seen are the adjustment point for C706.  The Y2K manual also only shows the 
single threaded shaft for C706 with no mention of locating T701 for 
adjustment.  For Z702s with a slug-tuned T701, I expected to see an 
additional hole for the slug but, so far, I've seen none.

Is the slug-tuned T701 similar to the slug-tuned transformes in the IF deck 
where the hole for the slug adjustment just wasn't included in the can?

It was a busy weekend so I didn't get back to any more testing, but I still 
plan to replace tubes and "sweep" the output can in hopes of finding what's 
causing the output to be so low.  According to Rich, his experience with 
all those Cosmos PTOs yielded much better results than what I'm seeing, but 
he also stated that he's never seen any common failures such as bypass 
caps, etc., so I'm still left wondering what could be wrong here.
