Do you have an ohm meter?

Just unscrew the transformer if you need to

How do the capacitors look? Any signs of bulging on the top? I'm asking because they have the limiting life of the amp. Since it's about 15 years old, there is only so many years left before they will need replacement too.

You can get the ADA1250-5 for about $2600 if you can wait 21 days. Also, there will be a Black Friday sale around Thanksgiving where you will get another 12% off. If you have bought from Axiom before you have a loyal customer discount as well.

The other thing to consider it the ADA1500 is not an AB amp so it is very efficient and does not get that hot.

Although the Rotel RMB-1095 is a piece of work, I love my ADA1500 and I would recommend these amps to anyone.

Those leads on the transformer are likely only short enough to reach their terminations. Not sure therefore Chesser will be able to move it far enough out of the way.

Rich, can you tell on the schematic what all drives those LEDs? Just not sure if those LEDs would be on with a blown fuse.

That thing must have a ton of capacitance which I think may be hiding underneath. If you did send it in for repair, re-capping would be a good thing as Steve suggested.

I could be wrong but I think the way the ADAs are designed, you just change out the power supply instead of having to get into de-soldering and soldering. If it really is like that, it would be very righteous!

That amp is 2850 after loyalty, "I can wait" and black friday discounts and taxes to BC.

The capacitors look ok from what I could tell but I'll look closer when I'm back home tomorrow.

I would love to buy that amp and most likely will one day...but I figure, why spend 3k when I may only have to spend $20 on fuses? Even if it only lasts me a year or two...its worth it I figure

Hell...it would be worth it to spend upwards to 1000 to fix it reckon. Power ain't cheap.

What a beautiful beast!

I have an Anthem PVA 5, 5 channel amp. It worked perfectly for 15-20 years. I retired it for about a year, and when I fired it up, the fault protection red light came on, no output.

I took it to George Meyer repair in Los Angeles. They replaced 24 caps with 105C caps, for about $550. I still haven't hooked it up yet, but they tested it in front of me and I am hopeful it will work for at least another 15-20 years.

Good luck with yours. It is a beauty!

And unfortunately it's going to cost me an arm and a leg to ship it somewhere to be trouble shooter and fixed...

And if I rule out fuses...who knows what it needs.

I'm fairly confident the fuses are blown. The family member I lent it to was terrible about hooking wires up backwards...playing with hookups while all powers were on, etc.

I'm confident it's the fuses *crosses fingers*

A fuse is $0.26.

Hey Chesser. Sell that amp to 2x6.
