Hi John,
I think that an iron vane type meter to read the voltage will give the
true rms voltage no matter what the wave form
Hi Jim
My situation is quite different from yours, but I
thought that my experience might be useful to you.
I use an old pole pig, in the power supply, used as a
high voltage source, for a number of HF, VHF UHF
power amplifiers. The high voltage was initially
excessive, so I used a 2 KVA
Hi John,
I don't have a digital camera of my own, but can easily borrow one and send
you a picture. They are heavy. About 70lbs. They use no filtering. They are
high quality, audio power amplifiers, in series with the secondary of a split
bobbin, shielded power transformer. The transformer is

Jim,
A familiar problem.
Had an old Westinghouse RBM rcvr that was loosing tubes...
All,
Familiar problem indeed. The manuals for my SX-9 and SX16 receivers call
for 110 vac input! I use an RCA WP-24A
Jim ,
I have had this problem one way or another for years ever since I have
started to use the old boat anchors. There are times when my line voltage
is as high as 129 v! This really plays havoc with a rig like the BW 5100.
The bucking xfmr seems to work OK for some other vintage enthusiests in

Folks,
The power company loves higher delivery voltages - makes your Kwh meter turn
faster since most of your house loads are resistive (voltage sensitive). Think
about it. I'd like to run my entire house on 115 volts, even the bulbs would
last longer. One 15Kva tapped transformer would do it

Never had a problem.

If you are running equipment you have to worry about because the line
voltage
is slightly high, its bad news, things are supposed to have some headroom...
I'm pretty much with you on this one, Brett - although I can see a
I am not an engineer but have visited with some concerning this
issue. Anyone with 129 volts at the outlets should call their
electric supply company and have it checked after they check the
calibration of their meter. Pretty much the standard today is 120
volts at your outlets. In my previous

enough that I am adjusting too often manually..Jeff..W0XV

I have the problem here. I have seen
Follow-Up on 20A.
I have an observation that is perplexing me. Some of my old AM Boat
Anchor gear was designed in the days when the AC mains power was lower. For
example on one of my Central Electronics 20a 's,I measured the
filament voltage (non-RMS DVM), and it came out to 6.9 vac
Jim,
A familiar problem.
Had an old Westinghouse RBM rcvr that was loosing tubes
till I found the fil was at 7v. WOW!
Looked at the P.S. tag and ac input was spec'd at 115 v
while my line was about 125.
Found an old TV compensation transformer with a +/-
10 v switch . Took care of that.
