So I scored Marantz 2600 for five bucks.....worth repairing?

Recommended Posts

Hi,

Just wondering if anyone can recommend a good tech in the gold coast/ northern NSW area to repair my op-shop find. The fuse was blown, and after having a peek inside I can see three big old rectangular resistors near the front that are cracked and burnt. Its also a bit dusty. I understand that they are supposed to sound good so I want to find out if it is worth repairing.

Cheers

You could try calling Clayton at The Speaker Specialist on the Gold Coast.

He'd be honest enough to tell you whether it's worthwhile repairing or not.

Clay's number is 07 5531 0600.

Good Luck !!

Russ.

Dunno who to suggest up your neck of the woods. I know the 2500/2600 very well. I was service manager at Marantz when they were released. They are very potent amps, but very difficult (read: expensive) to service. OTOH, they were pretty reliable. I'd figure that you need to budget around $300.00 ~ $800.00 to properly service the amp. Output devices may be difficult to locate nowadays. OTOH, if you don't want to fix it, you'll certainly recoup your money on eBay.

Sound quality is a subjective area. At the time I owned a 2500, I also owned a (American built) Marantz Model 500 (come to think of it, I still own the Model 500). The Model 500 utterly anihilated the output stage of the Model 500, sound-wise. Measurement-wise, they were virtually indistinguishable. Still, there are many people who view things through rose coloured glasses. They imagine that the 2500/2600 sound great, so you'll easily move it on if you need to.

For 5 Bucks, you're laughing.

Thanks for the advice guys, It would be kick ass to get this repaired and running in my home studio. Curiosity got the better of me and I replaced the fuse to see if there was any life. The fan started and the front lights came on for a moment then the lights went off. I ran it for about two seconds then turned it off, and the aforementioned resistors gave a tiny waft of smoke.

I rang the speaker repairs place and he put me on to someone but it's a fair hike from where I am. I have found someone closer and for the cost of a quote, I may be able to see if he will give me any joy.

Thanks again and I will keep you posted.

Hey, the local guy I found comes highly recommended from some muso mates. They reckon for anything that drives a speaker he is a genius. Fifty bucks for a qoute, I am taking the marantz over there today.

Update;

After a brief phone call with my service guy, I am feeling confident. His preliminary findings were very positive, but he said to not get over-excited until he goes way down the "rabbit hole". He also said that if I was willing to spend the money for a proper repair he would waive the cost of the quote. Filter caps and transformer look good and the dust is recent - from storage i guess. The only problem I have is that my wife read Mike.L's post regarding value!!

Good luck. It will not be a cheap repair. The 2500/2600 amps are very difficult to service. Parts are also expensive. Sound-wise, they suck. They represented what was wrong with the 1970s power race. The 2600 is a very powerful reciever though and commands serious Bucks on eBay.

I reckon you won't get any change from at least $400.00.

ZB, how did your restrained comments in your earlier post;

so quickly turn into the devastating (though concise) assessment I have quoted from you at the top of this post!?

Not sure, really. I was working for Marantz when I purchased the 2500 and 500. I moved from a 1200b (US built) to the 2500 and, although managed to make more noise (important for a 26 year old) I was left with considerable dissatisfaction with the sound quality. I had earlier spied a Model 500 power amp in the corner of the workshop and I fronted the company accountant and asked if I could buy it. I was required to sign a suprisingly legal-looking document, promising never to make any claims against the company about the Model 500 under any circumstances ever. The 500 was the most hideously unreliable product ever manufactured by Marantz. Legend has it that from cradle to grave (from the first design drawings, to the last warranty claim) the Model 500 cost Marantz (then Superscope) 3 million US Dollars. That was for a production run of 300 amplifiers, which had a RRP of AUS$1,500.00. It was a considerable loss for the company.

Anyhoo, I fixed the 500 and connected to the preamp outputs of the 2500. What a revelation! It obliterated the 2500. I ran the measurements of both amps and they were virtually indistinguishable. I finally dumped the 2500, in favour of a Dynaco PAS3X (highly modified).

Very thorough explanation, thanks, and an interesting story. The Marantz 500 sounds like a fascinating amplifier, the equivalent of the Triumph Dolomite Sprint I owned when I was about 20 - when it went, it was very fast and cornered brilliantly, but it was hideously unreliable.

It cured me of performance cars for life. Sold it to an aeronautical engineer who knew what he was getting in to. Definitely a better owner.

The Sprint was the WRX of the day, without the reliability, of course. The Model 500 was very favourably reviewed by TAS, with one proviso: TAS would recommend the amp, if only they could get to operate for more than 6 weeks without blowing up. FWIW: I've made more money from my Model 500, hiring it out an ad company as a static display, than I paid for it. It is presently non-functioning. Last time I looked, I could probably get more than US$2.5k for it. If it was working, of course.

if you decide not to repair it let me know as im collecting Marantz gear and restoring them and wouldn't mind adding one of these to the collection :cool:

I would not put that fuse back in again till you find the problem...

Cheers for the advice aokman but I took it to the tech for that reason...

I would like to see if he has any luck first. Ideally, the bongo-playing karmic hippie in me would rather see it working before I flogged it off, but hey, I only have so much room on my pile of "cool-stuff-that-I-should-do-something-with". Speaking of wasting an arvo, You guys might be interested to know that The Boston Acoustic A70 series II's I found at the tip have been re-foamed and are sounding pretty sweet!! It's a shame they are a bit small for the 2600. Lucky for me my drummer had an old sansui doing nothing.

been trying to contact the tech for a month or two now but i found out his mum had serious health issues, and he had trouble finding a schematic.

i can't be bothered waiting any longer. do you guys have a thread for classifieds or something? i know some forums frown upon posting for sale ads in the wrong thread.:D
