[Hallicrafters] FPN-300

[Bob Arthur]

I have a Hallicrafters FPN 300.  It does have a couple of tubes and it is
heavy, so I hope it qualifies as a boat anchor.  I have a problem with it.
When I power it up it receives fine and has about 100W output on a dummy
load.  Then, after about 30 min, the output goes away and so does the
receive. Has anyone seen this type of problem?  

 

Thanks

Bob
