HW-16 Problem w/side-tone

[Martin Buinicki]

My thanks to all who have offered advice. I have found the problem! And it 
was mechanical, not electronic: The vfo input jack center lug was grounded to 
the transformer case.

Here is some interesting history on this rig. I got it last week as a 
package: "nearly finished HW-16, unopened HG-10B vfo, and SP-600 speaker, 
unassembled."  Cost me $150.00, the asking price.

In inspecting the HW-16 to check construction progress (none of the items 
except the vfo has a manual), I found that it was complete except for the 
connections to the meter, used to read PWR and PLATE. As these are not the 
last steps in my old manual, I was puzzled. Upon plugging it in, I got 
nothing- no tube filaments, no pilot lite, zip. I was checking the power 
supply when I noted that one lead of the 110V cord was connected to a 
terminal strip, all alone! No other connection. I imagine, therefore, that 
the rig never worked, and the disappointed builder then never even started 
the VFO and speaker that were to be parts of his station. Sad, huh?

Of course I have found multiple other glitches; tube sockets not soldered to 
the pc board, components not soldered to terminal strips, etc. But, with 
time, I hope to have this rig up and running for the first time!
