Adcom GFA-565 monoblock amps for sale

[Cursed1]

I have a total of 3 Adcom monoblock GFA-565 amplifiers for sale. BIG POWER 300 watts each at 8 ohms. I am asking $375 each for them. They are in great shape. I do not have the original manual or box for these. If all three are bought I will offer a discount. I will only ship to the lower 48 insured. If you have any questions please contact me via PM or by email at audiovideoman@comcast.net


Thanks!

Bump for a nice set of amps

[jakelm]

If I had the cash H9, I would. They would go nicely with my Hafler. Nice deal.



Little bump for ya...

[danger boy]

I never knew Adcom made a mono block amp.. this is news to me. big, beefy and powerful. nice.

[sophie]

well my dad is talking about redoing out living room and adding a ht, might try and talk him into 2 or 3 of these.

[heiney9]

Argueably the best Adcoms around. Designed by Victor Campos and Walter Jung.

[hearingimpared]

Very good price too! When mine go up they will be much more expensive!

I guess you've never read my boring signature.

[thejck]

anyone know how these would sound with the rti12's

Better than you could ever imagine. Those speakers will come alive and reign terror anywhere they go :p

[dkg999]

I'm not sure "reign terror" is approved audiophile terminology :rolleyes:

[thejck]

would they be better than a gfa-555 or will i not be able to tell the difference

[heiney9]

From a purely musical 2-ch POV with a decent pre (not an AVR) yes. For HT duties perhaps not unless you have a huge room and listen at ear bleeding levels. However there is no denying the coolness factor of having to huge mono blocks in your rig :cool: .

If you have the extra coin go with the mono's

Using audiophile approved terms seems to create contraversy, so I'd thought I'd start a new trend. ;)

[george daniel]

375.00 each is a very inexpensive way to get into decent mono's,,nothing shabby about these amps :)

[JimBRICK]

these would be awesome with that rogue audio preamp in the fm as well

[hearingimpared]

bump

[tom t]

theres a pair on audiogon now for $750 pr. same price

[dorokusai]

They've(Audiogon) also been repaired once and are on their way for another repair job once purchased.

[tom t]

i saw that,good point

[jdhdiggs]

Bump...

Hmmm, Could I actually use 5 of these beasts? hmmm.....

Guys, this is a stupid low price for things.

[dkg999]

The fact that these are just sitting here is just crazy! Good gear, good seller, great price!

If H9 would just build his stupid interface cable so he could use any amp with his SDA 1C's, and then buy these, we would need a jackhammer to get the smile off his face ;)

I'll even pick these up for H9 and haul them out to him. Game on!

You are correct :) , but I've got my eye on another prize. I just need to wait for one to come up FS. I love my Adcom but after 20 years it's time to move in another direction.

If I had a use for these at all they'd be mine. I recently passed on my bro's pristine condition GFA 585 which is the same concept as these only in 1 chassis. He was going to make me a pretty good deal.

This $$$ is below the avg. market value of $850-950. For someone in need it's a no brainer.

H9

EDIT: The negative terminal can be tied to together for use with SDA's rather than having to use the AI-1 cable or a home made brew.

[sophie]

cursed would you want to do a trade, iv got a gfa 5500 that i could give plus cash. i relay can't use these untill i get some 1.2's but o well.

[Willow]

I just find them to be massive, or I'd buy them I need more amps!

[thejck]

are there known issues with these amps and bad capacitors...would they have be worked on now or in the future. I would like to buy these but i was concerned cause I read somewhere about that. if they work great now will they continue to work great. I plan on giving them enough cooling and not really pushing them too hard.

do you know what the age of these amps are?

[heiney9]

There was a run of this model number and the 585 as well that had defective caps in them. Not Adcom's fault but the manufacturer of said caps. It's my understanding that if there hasn't been an issue by now chances are you won't have an issue. There are replacement caps available from other sources (no longer from Adcom). The biggest problem is when the electrolytic seeps on to the boards. It's corrosive and a PITA to clean. The boardds are no longer avail. so cleaning is the only option.

If it were me I wouldn't hesitate to buy because of this issue, but once I bought them I'd replace the PS bypass caps as a precaution. A little ounce of prevention goes a long way in this case as cleaning up after the leak is a major PITA. Plus these are getting to be around 15 years old so it wouldn't hurt to do it anyways.

That's my .02c

[mox]

can you go $150 for one of these?

[F1nut]

$375.00 to $150.00............that's just insulting.

[dorokusai]

Absolutely.

[DarqueKnight]

And F1nut doesn't even like Adcom's.;)

[Gaara]

$375.00 to $150.00............that's just insulting.

Isn't that why Mox is here, lots of his threads seem to be to pick fights and brew trouble.

[snow]

$375.00 to $150.00............that's just insulting.
Wow I dont know what to say. :eek: shakes head <<<<<< I have a friend that bought 2 the other day for $800.00 and was very pleased to get them for that. I will ask him if he wants these 3 also. If these were local I would be posting about my listening session right now.

[engtaz]

How would you run them with sda's?

[snow]

How would you run them with sda's? You take a cable and run from both negative binding posts to each other which will make it a common ground.

I believe Joe/ hearingimpaired has a thread on these exact models and how to do so.

REGARDS SNOW

[engtaz]

I thought so but almost tried the same thing with mono 555's but asked before I blew them up. Adcom and H9 said no way Jose. By the way thank H9.

There is nothing wrong with the amps in any way shape or form. I am listening to them right now. Keep me informed if you would like a package deal!!!

[heiney9]

A stereo amp run in bridged mono is a completely different animal than a mono designed to run in mono. For SDA's the 565's can have their negative terminals tied together (with substantial wiring) to create a common ground.

FWIW

I really have no use for that. If you can work it out then give me a shout. Thanks for the offer.

[dkg999]

We're just a humorless bunch of people :rolleyes:

Now let's sell these amps since we've totally demolished this For Sale thread!

[dorokusai]

I cleaned this up a bit so the thread is a little more on track again.

[John in MA]

Wish I had the cash right now. I actually was looking for a pair of 565s earlier in the year when I could afford it.

[Cursed1]

I cleaned this up a bit so the thread is a little more on track again.

I just was able to check the posting and I didn't even get a chance to see all the fun. Darn!!!!

Are these class A/B or A?
Thanks

Lets find these things a new home!

H9

Please explain H9. I thought mono was mono. Besides the ohms load it is capable of handling, whats the difference? I was thinking of getting a stereo amp and bridging it out for my center chanel, should I think again?

I'll start a new thread for this...please excuse my interuption...now back to your regularly scheduelled program..

[BaggedLancer]

From a purely musical 2-ch POV with a decent pre (not an AVR) yes. For HT duties perhaps not unless you have a huge room and listen at ear bleeding levels.
H9

Everyone doesn't listen to HT at ear bleeding levels? I thought I was just going with the flow having my house shaking.

These amps would do ear bleeding loud or just excellent reproductions at lower volumes.........whatever you prefer.

[Texas42]

Great amps for the price. I've owned several sets before and they will cleanly power just about anything out there into really low loads. I've used them with Carver Amazings and they ran a bit warm but always had the goods. Usual street price is about $400-500 each. These are very fairly priced.

[bdaley6509]

Happy Birthday to me! Payment sent for 2 of them. Hopefully these will be a good match for my new LSI15's.

[snow]

Happy Birthday to me! Payment sent for 2 of them. Hopefully these will be a good match for my new LSI15's. Congrats to you on your purchase. No doubt in my mind they will mate nicely with your LSI -15s.

And if for some reason you dont like the sound at this price you can always resell and get your money back.

[tonyb]

Nice grab on these baby's.With soo many people asking about amps,it's a shame it took this long.Enjoy the new speaks and amps!

[hearingimpared]

Great price for those. . . enjoy!

[tonyb]

Yeah,Joe....remember this thread when yours go up on the chopping block.:D
By the way,the scampi was great,thanks to you and your lovely wife.:)

[audiobliss]

Ha, I'm glad you grabbed them. I was gonna say joeparaski needs some more amps. :D

[analog97]

Gents: I have the 1.2TL's and would love to power them properly. I replied to the seller, so we'll see. I just need your help on this "common ground" issue. Are you all saying that by tying the amp negs together, this will eliminate the chance I would blow up my Polks? That is my only real concern, except that cap leakage just pointed out. Did I understand this happens on the 565's? Or, was this unique to the 585's? Thanks again.

[analog97]

oops...that's what I get for skipping over a few threads. My 1.2TL's will just have to wait....

[Cursed1]

Amps were delivered today to the new extremely satisfied owner. I still have one for sale if anyone wants the last one at a screaming deal!!!!!!

[Texas42]

I got dibs on the last one! PM sent.
