Success...sort of.

Yup, my SSTRAN now comes in nice and loud (and on the original speaker, yet!). But the quality of the audio...I don't expect high fidelity out of this little set, but the audio quality is sorely lacking. Perhaps the voice coil is rubbing. I also found that the 1st IF breaks into oscillation if the adjustment screws are tweaked too much. And it goes into oscillation on the SW band.
Could be (at least partly) lead dress issues. Since this set no longer follows the original schematic, I did change some of the wire routing in an effort to make leads shorter and more logical.
The circuit mods eliminated two bakelite blocks and a few resistors.
A big concern I now have is: How in the heck do I align this (AC/DC) set without tripping the GFCI that protects this circuit? I can't attach my signal gen to this radio without tripping the GFCI.
