#1 What's your mains voltage ?
I'm trying to be crafty with my new tweeter amp and build the filament supplies ( especially the DHT one ) with just enough reserve voltage in for typical UK operation, in the places I am likely to take the amp.
I'm interested to know what AC people have in their locations.
( I expect Ali Tait can tell me a lot more ! )
Anyway , if you have time and a reliable multi-meter, let me know what you find.
So far, I can say mine was 248V last time I tested it - and has always been around 247 or 248 as far as I can recall.

Tested it last week after my site tranny packed in, I got 247v on the primary side
#3 Re: What's your mains voltage ?
mine varies between 242 and 255v.
I did a long thread back in the day because it was causing me grief as the bias for my F6 followed the mains voltage and made life very trixy. Since our street had a new main installed there are times when the voltage goes outside the acceptable limits.
right at this moment it's 253.4v

Ah yes I remember about that (now).
Thanks
Keep 'em coming !
I was thinking of allowing min 240V for my amp to work outside of North Wales, Nick suggested 220-255V ( I think his tongue was slightly in his CE cheek ) but I'm keen to see if anyone has less than 240.

242Vac to 245vac here.
#6 Re: What's your mains voltage ?
Don’t have a meter here, but in Dunfermline it was a pretty steady 240-245.

Cool I running at 235 volts in the Shore of Beds...
Philosophers have only interpreted the world - the point, however, is to change it. No it isn't ... maybe we should leave it alone for a while.

I like it though - a premonition of sea-level rise !
Also the first entry at under 240V.

Kent calling......
It's usually about 248vac here, but I've just measured it now at 250vac....and 24mvdc across it too....

Down in deepest Devon, generally around 247V.
The world looks so different after learning science. For example, trees are made of air, primarily. When they are burned, they go back to air, and in their flaming heat is released the flaming heat of the Sun which was bound in to convert air into tree.

My APC SmartUPS in the shack logs the mains voltage. I've posted graphs from it before - it has hit 250V....
Theory is that being out in the countryside means that they have long crappy cables (ours is an old 3-phase 100A SWA cable with oiled paper insulation!)
As they have to deliver 230VAC to whoever is at the end of the supply, the tap the substation for a higher voltage...
Which is why I use a decent UPS to supply stable, predictable, 230VAC to critical kit - make a real difference to the HT on amps etc.
