Hello all!  I have a Globetrotter Amateur with a problem I can't track down. 

Radio works on all bands.  It is not working well on LW, but does seem to work. Alignment may improve that. 

On MW, it works just fine above about 780khz; below that it goes dead.  It is the Local Oscillator that quits.  

I touched a soldering iron to TR8, and it came to life, until the transistor cooled down.  I thought it was bad, but changing it did nothing.  I then found that I could do the same to TR9 and it would work.  I have also found that some resistance added to the base of either transistor makes it work okay, but has consequences on FM.

 

I have checked resistors and bridged capacitors in the oscillator section, checked for cold solder joints, etc, but haven't solved this.  

Anyone have an experience like this?

Thanks,
