  Con Edison has dropped the voltage to 105V  [ stanard circuit]- 112V [ separate circuit] today. How does this affect our gear ? is it safe to turn thr gear on ? Will it stress anything ? Thanks.

In my (not so professional) opinion, electronic stuff would be fine at 105.
That is, unless there's a heavy, sudden draw on the grid and they can't recover fast enough. You're nearing the shutdown threshold of some equipment. I had a situation a while back where I was monitoring my line voltage for a month or two because my home theater projector, AV receiver and a couple other components where shutting off.

Doesn't seem right to me Charles. I'd hate to be the person on the other end of their customer service phone number, that's for sure.

Good luck. Might wanna look into battery backups for your more sensitive equipment.

You might want to look into a regeneration unit like the PS Audio Power Plant if this is more than a temporary condition. 105V should be OK but borderline, IMO.

105V AC is no sweat for our equipment.  The power amps will be down a bit in power but no problems with musicality.

With any home electronic equipment, now is the time to make sure it is connected to a good power strip with transient protection.  Low line AC conditions are when there will be more voltage spikes than normal, and normally is the "season" for power supply rectifiers blowing, for example.

Thanks for the response Gentlemen.

For those with tube equipment things can get a little tricky. For instance normal 6.3 volts on the filament at 120 vac drops to approximately 5.51 vac with 105 vac line. This is a little beyond the 10% variance allowed for indirectly heated tubes (5.67). For heated tubes one should be within 5%, or 5.98 vac minimum. There could be a slight variance since the filament does not get as hot.

Otherwise, power output will be less, fixed bias may need to be adjusted etc.

Cheers.
