250 watts continuous into 8 ohm, 400 watts into 4 ohm continuous.

I plan on bi-amping it with the recently aquired Hafler to drive my Legacy's, use the Hafler for the low end and the Adcom for the upper.

I still have music my neighbors haven't heard yet.

I heard from Glenn this morning about my Adcom, here is a quote from his e-mail

"OK...the 585 is done. Leaky caps, as you had supposed, and the servo opamp misbehaving. The driver boards had to be removed and cleaned with Simple Green in an ultrasonic cleaner to get rid of the old electrolyte that leaked from the bad caps. All the electrolytic caps were replaced (except for the four large power supply caps, which look fine), and the two servo opamps were replaced with nice Analog Devices OP97 amps. The pre-drivers also needed replacement, as these were apparently replaced at some time in the past, and the devices used were simply too wimpy for the job. I managed to locate a few of the out-of-production originals at a ridiculous price ($10 each!!!). I would have used something else cheaper, but these are some unique devices and I was truly afraid that a substitute here would have resulted in poor performance. Also had to replace a few out-of-tolerance resistors. All the stock power output transistors were fine.

Anyway, put it all back together, and it runs fine. I measured clipping at 280WPC, and at the rated 250WPC, THD+N was nearly unmeasurable at 0.0028%, a stunningly low figure."

Now just to get her home and blasting out the neighbors!

Four month wait is a killer! It will be worth it!!

thats good news Jim. it should make for some really sweet music.

A year and 4 months to be exact.

Jim

I am still waiting on my pre-amp, its been 4 months, I am getting antsy too. I cant wait to get my rig up running with all my equipment. I hope to hear about your impressions soon.

The GFA-585 is one I would love to have in my Adcom collection. It sounds like yours will be an excellent example when you get it back. Please let us know you impressions.

I should be getting my Adcom Sunday sometime. With the load I run amps at I have decided to try a cooling fan on it when I get it, Adcom made one for it origianlly as an add on, since they are no longer available I did a little looking and have ordered one of these http://cgi.ebay.com/ws/eBayISAPI.dll?ViewI...em=260443469287 I will let you know what I find after I have had a chance to evaluate it in use.

Jim

Wow, 16 months to get fixed..... did you piss Glenn off or something?

Not that I know of, he is just in a high demand as far as I know, I held out as it was him I wanted to do it.

Jim

I see 535s and 555s often, and the occasional 545, but the 585 is not a common site. I think I've seen more Yeti.

Comgrats and good luck with it.

I have been looking into the power consumption rates for the two power amps I plan on running, I was going to pull one dedicated circuit to them, after looking at consumption rates I am wondering if I should pull two while I am at it.

The Adcom and the Hafler both pull around 1200-1300 VA with the Adcom claiming 1500 VA peaks, when opened up, I am going to use 10 guage wire but still think I might be better off to run two circuits. Any thoughts on this?

On another note, I picked up a copy of this at a garage sale a couple of weeks ago to prepare for the big moment.




Jim

Nice score!

even if it offers no advantage, it certainly wouldnt hurt to run two and it doesnt add much work over doing one anyways...

I hope you realize that I was just kidding.

Glenn is so backed up now that he's about out of room to store stuff that's in the repair queue. I'm going to send the next few items that I want refurbished to some of the other highly regarded techs that I know of from AK.
