Jerry (and all)	

A good point. However, these rigs were meant to run at a lower voltage, W9GXJ,
Stan Shure, published some bench test results on this several years ago. They
may be on the HCI web site. If not, I have them. Most rigs performed up to
factory specifications at anywhere from 95 to 105 volts AC.

Just a crazy thought!  Are you getting 115V AC or above from your shack house
circuit?  I know that I am only getting 105V to 110V here.
Remember this is one of the hottest summers we have had for many years.  All the
AC's in the neighborhood are running full blast.  I know mine is running 24-7.

Tighten every machine screw and nut that goes through
the chassis or any shield.  All of the grounds in the
receiver are made through these and they work loose
and/or gain corrosion over the years.  This means
every screw holding in a tube socket, a terminal
strip, jacks on the back of the set, screws holding
variable capacitors to the chassis, and so forth.

I "fix" about 95% of the "strange" problems in "boat
anchor" equipment by doing this.

I had to tighten all of the machine screws in my
Collins 75S-3A a couple of months ago because it
started having intermittent problems.  It has been in
basically the same location for about 30 years!

By the way, there is no grid voltage going into the
rectifier tube.  What you are reading is filament
voltage.

Filaments are reading 5.5 vac all the way around
(Calls for 6.3) Plate supply is good too at 280 vac
per side of center tap 560 vac total checked going
into the rectifier.(Calls for 290/580) Grid voltage is
5 vac going into rectifier. (calls for 5vac)
