   Yo'

           I just came down into the shop to do
a little work, and as usual I checked the AC line
voltage , Found it way up to 125.7 today.

           That's the highest I've seen it ever!
I'm just south of Cleveland.  My frequent checks
usually read about 120.8 to 122.8 .

Welcome to cooler WX...less HVAC demand means higher line V.

Utilities usually will roll it back this time of year.

Ours is 125 @ 1220 hrs 10/20.

  Hope u have plenty of spare tubes... 

115 / 6.3 = 18.25  turns ratio
125 / 6.3 = 19.84  turns ratio

115 = 6.3 Fil
125 = 6.84 fil

    Face it man, Even if u have a Sh*t Load of spares
your BA is on "Borrowed time".

Well, of course the vintage gear gets the 'adjusted' line.

What modern crap we have just doesn't care.

All the motors here love the higher E.

It is a LOT easier to drop line E than to raise it...

Call your utility company and ask them to check it. If it's that high, they'll adjust it.

AC line in NJ is 120 nominal by tariff +/- 5%. Will check on Monday for Ohio. That range is 114 to 126. Higher voltage may be due to a line capacitor problem or tap changer issue at at sub station. Send me ur info to staylor@firstenergycorp.com. Are u Cleveland Illuminating or Ohio Edison?  Seth KC2WE.  Reliability Engineer. First Energy, Jersey Central Power & Light.

Added info. Most boat equipment is designed for old 117 volt standard. Most all electric utilities supply 120 volts + or - 5% by State tariff. If you want precise 120 suggest using one of those Sola voltage regulators. 110 volt standard is "prewar".  Seth KC2WE.

We did just get a new "Pole Pig" this summer,  after running up
my TRC-75 MG set that runs off 110 DC I think I cooked it.
Lights for a few lots either side of mine were "Blinking"
 I just checked it and now and am
seeing 123.3 .  Yes I'm on CEI in Parma, Ohio, just a few
miles north of the site that caused the "Great Blackout" Hi Hi...

         I have my radio bench power being bucked by a big 12.6 V
Fil. Xfmr.  and that usually runs around 107 - 109.   I guess it's
probably not out of spec, but I have never seen it that high before.

Thanks Seth,

Last Spring I noticed things were running a little different around the house. Various electronics and devices with motors sounded different.
Got the fluke meter online and we were down to 101 VAC. I called Penn Power and within an hour a rep came to the house and said the voltage is back up to 125. They were having problem with a "card" at the substation about 2 mi from us.

All my stuff is tubes, I pay no attention to the line voltage and have not had a tube go bad in service in 30 years.
