[AMRadio] Globe Champ 350

[rbethman]

  Kim,

You've gotten a LOT of "great" advice.

1) Replace the original capacitors.

2) Do the burn in.

Now for the "heresy" aspect:

     The power xfmr was designed for lower voltage from the wall.

     Try adding a "bucking" transformer.

     Consider an "outboard" transformer for some of the filament and low 
voltages.

You have one heck of a gem!  Do your best to keep it alive and well!

Regarding the HQ-170.  What precisely do you want/need?

I have an original manual for the HQ-170 that I obtained off "Flea-Bay".

I also have a 5MB PDF for the HQ-170A *IF* your E-mail can handle it.
