[Hallicrafters] EICO Signal Tracer

[Oliver J. Dragon]

Hello All,

Last weekend I picked up a nice EICO Model 147A Signal Tracer. It needs 
some minor restoration and I would like to locate the construction manual 
that goes with this unit. I was able to download all available pages from 
the BAMA site but the file is largely operation info and is mostly 
incomplete in the construction area. Does anyone have a manual for 
sale/copying, or can you steer me to a site with this info?

I notice that the tube sockets appear to be rivited rather than mounted 
with the usual screws. At first I thought the unit might be a factory wired 
one but the serial number does not end in "W" which I suspect denotes a 
factory-wired unit. Any thoughts?

Also, for the front panel mounting screws, the parts list calls them # 6 
P.K.  I know they are sheet metal screws but what does the "P.K." mean?

Thanks!
Ollie.
