Equipment Protection, Monitoring Electricity

In ored to understand yourself and make us understand, you should probably mention make/model of amplifier and nature of the problem. Is it audible? Is the amp operational?

I had an amplifier malfunction and the possibility that was proposed to me was that since a transformer blew about a week prior to the malfunction,

If the utility power transformer blew up, yes that could have caused a severe over voltage condition. An excessive over voltage condition will indeed damage electronic equipment.

Check with other tenants in the apartment building and ask them if they experienced any problems from the power outage.

Ok, the electric company said that they show good electricity reading to the meter.

After replacing the bad transformer I would hope so!....

Question should have been, when the old transformer blew, what was the voltage the secondary of the transformer was putting out? Their honest answer? No idea....

File a claim with the power company.... They should pay for the repair of the amp.

I can't disagree with anything that anyone has said. Its ultimately up to me at this point.
Thanks!

G.,
I think that one of these power conditioners might go a long way in addressing your issues:

APC AV H15

or:

Belkin PureAV

Both units provide some of the best surge protection available. Each will provide separate, conditioned power outlets to each of your components and will display discrete real-time current and voltage data.

I think the APC may offer better voltage regulation features which seems important in your case.

I'm fortunate to have good quality power services, and own the Belkin. The emi/rfi filtering seems excellent, programmable power features are first-rate, and the Belkin warranty alone is worth at least the $300 price of the unit, for me. Example: My power service was hit by lightning several years ago, and three of my components were damaged (3 others were not, even though no protector can fully safeguard against lightning, IMO). Belkin was amazing. Within 3 days I received a new PureAV unit, and within three weeks, I received a check for damages.

Both the APC and the Belkin are selling at deep discounts to their $5-600 original prices - very inexpensive for the peace of mind provided.

Good luck, and please post on any solutions you find.

Look, to put yourself at ease with this, there is a simple solution that you can handle yourself more precisely and for much less money than involving an electrician. Go to Radio Shack, Home Depot, Hardware Store, or etc. and buy a decent, but good value multimeter. Nothing is more simple than checking home AC voltage with a meter. Doing it yourself allows you to check it at all different times through the day and night. Read the meter's instructions and take note of the safety precautions since you seem to be new at this. Don't get too worried if you don't understand absolutely everything. All you need to know is the AC volts test. It's as simple as this: Set the meter for "AC Volts" and stick the probes into the socket. Read the screen and note the voltage and time of day on paper to compare how it may fluctuate.
