Negotiableterms's Marantz 2600

EchoWars said:
OK, now that it's up and running, and essentially done, I've been listening to it the last few days. If you told me that I'd never have to tear into it again, I'd retract that last paragraph I wrote in my previous post.

I really like this reciever...from an operational and auditory viewpoint. Might have to find a 'problem' and keep it here a while longer. :)

I was waiting to hear that. It couldn't be the holy grail of Marantzdom without good reason! Tell me EW, how does it compare to the Kenwood 700M, 700C combo?
 
Thanks for the posts about this unit, I was fascinated reading them. If you ever feel like going into more detail about your opinion of the design (electronic and physical) I'd be interested to hear it.

I was a 2600 owner for a period of years until recently, when it found a new home with a fellow AK member. Never got nearly as much use out of it as I should have. Early on I had no speakers worth setting up such a massive machine for. Finally when I did get the rest of my system to that level, other factors got in the way.

I took one look in that cabinet and thought "no ******* way," especially for a shadetree tinkerer like me. Far more goodies stuffed into the thing than seemed sensible. I got the feeling that, should anything bizarre happen and the power supply went poof, I'd basically be watching $2000+ go up in smoke. Figured that kind of change would go much farther in audio equipment with no collector's value, unlike the mighty 2600.

Now I've moved on and have been trying various seperates. Next up is a dead Heath 1640. Properly necromanced it should get close to 2600 power, and be easy to work on with split and bailing wire. :)

Not fair to compare this receiver to separates. As nice as it sounds (and it is certainly near the top of the heap for recievers, for sure), the sonic advantages of something like a rebuilt/modified 700C, coupled to a straightforward amp like the 700M is tough to beat. Apples and oranges.

I'll likely keep the rest of my criticisms of the 2600 to myself...too many Marantz lovers around here. ;)

I'm also beginning to doubt the 'Marantz 2600 dead-transformer' problem, and suspect that it may be a myth perpetuated by techs who find troubleshooting this unit too involved. That isn't to say that some 2600 somewhere may not have smoked its transformer, but I'm a long way from believing it is it an endemic issue with these receivers. Too many opportunities for a Bozo tech to do something stupid and blame it on the transformer.
 
Know what a round tuit is? When I get one, I'll take some pics. Inside pics suk on silver gear, and it's been a tad wet lately to drag a $3500+ receiver out into the rain.

I think you are right!

To me, the 2500 is the original design, the 2600 is a hot-rodded 2500. At Marantz they saw the SX-1980 and Sansui G-33000 arrive, so the engineers had to make advances fast. so they squeezed out a few volts more from the transformer to get the magic 300 Wpc. The 2500's 100Volt capacitors had to be tuned up to 105Volt - a very odd value. Throw in the 2130 tuner's quartz lock, ready is the all time BIGGEST MARANTZ RECEIVER.
It is true, its hard to work on a 2500/2600 for a technician, but compared to the competition, to me it has the best design for a monster receiver, compared to the SX-1980 or Sansui G33.000. The Sansui takes up 3times the real estate of the Marantz, is more a preceiver with strapped on poweramp.

In Germany you can buy a good Marantz 2500 for around 1500€, a good 2600 costs around 2500 € that's alot of money for 50Wpc more and a quartz lock!

Just my 2€ cents, Helmut
 
OK...for Fisherdude, and anyone else who cares to look.

Nice pics. Those interior shots are the ones that made me shake my head. Beautiful machine, though. Mine only had a few hours on it since new--time-warp-like. I miss seeing it lording over the listening room.

Got my AA-1640 today. All the size and weight of the 2600 but no preamp, tuner, or scope. :D

Very nice post! For Marantz lovers, it reads like a good novel:yes: Thanks for your time to put the post and the pictures together.

The fan is nearly silent when in low-speed mode. In high-speed, it's a screamer. Fan is fine...it's just moving a lot of air when high-speed kicks in, and you can't do that silently.

I would like to know how to determine if the fan is operating at low or high speed on my 510 amp? I have fan noise, replaced the motor and still there. It is not moving air noise, it sounds like the sleeve bearings in the motor. I found several potential ball bearing motors to replace it, but I want to determine if possibly the fan is operating at high speed from the start.

Thanks again for your post!

Is it a 120V fan? Did you connect it to 120V before you installed it to see what kind of air it moves? You're also assuming that the 510 buffers the fan through a resistor like the 2600, and I really don't know if that's the case. You'd have to study the schematic and see how it is wired in.

Plus, to get the 2600 hot enough to force the fan to high-speed, I had to run it at 50WPC into dummy loads for a good 15 min or so. Not something you want to duplicate with speakers probably.

It is a 120V fan, it's the same size fan and tunnel cooling system configuration as the 2600. I think the Muffin spec was like 105 CFM which is a whole lot of air. It's rated at 45 dBA is I remember correctly. I do have the Service manual, what should I be looking for?

I looked at the schematic and there is a 380 ohm 15W resistor, and 2 thermostat switches.
 
I never got my 2600 into high speed the entire time I owned it. Ran pretty cool from what I remember.
