Improving Sensitivity in Model 80
#1

In working on a Model 80 AND a Model 84 recently, and comparing the two schematics, I've come up with a way to improve the performance of the 80. It's quick, easy, and painless to do (unless you burn yourself with your soldering iron). Icon_smile

Complete details of this and another performance modification to Model 80 and similar Philcos have now been posted at Chuck's site, the Philco Repair Bench, in the Service Tips section.

You may be amazed at what a Model 80 is truly capable of after making these simple mods.
