Request: ARP 2600 Owner's Manual.

Post by smetak » Fri Mar 02, 2012 7:54 pm

Greetings,

Being new to analogue synths, went hunting around for some info on the basics. Needless to say, stumbled upon the excellent thread:

viewtopic.php?t=44345

And picked up a copy of the ARP 2600 Owner's Manual and began to read through it - I am amazed on how well written and incredibly didactic it is! I have attempted to print the PDF file to make my own notes and underlines, but, unfortunately, the copy is quite small and very hard to read when printed.

Does anyone have another copy, a bigger, better scan of the manual? If so, I would be eternally greatful for an upload.

cheers, w.

Incidentally, I don't really know if this is the best place to post this request - if not, I hope that the moderator can pordon me.

Interestingly Jim(?) rewrote the manual for the TimewARP 2600.

He commented something along the lines that he didn't have much time with the ARP when he wrote the manual the first time.

Pretty amazing!

The writing is amazing - the concepts are clear as crystal; it has helped tremendously with understanding the basics and being able to mess around with the system I'm currently building.

I have a copy of both the 2600 and 2500 manuals somewhere. The 2500 is a good read too.

I checked Google Street View to see the location of the old ARP factory according to the address in that 2600 manual (which, as others have pointed out, is a good read).

Interestingly, though an adjacent road is captured by the Google van, the one ARP was on is not.

I wonder why..... :tinfoil:

Sweet, just re-grabbed the manual.
I might even print it out and go it page by page with my 2600.

We're managing some reference ARP2600 docs on github. There's a full technical manual that was recently scanned by a nice person over on the facebook, I'm looking for other quality scans to post to the site.

Add Sam Ecoff's "Fundamentals of Music Technology" to your collection. It's a very thorough look at the Arp 2600.

You might rather look to correct the errors of fact and errors of omission on your documents.

Some things, like the voltage processor section of readme.md where it states that "the section processes four control inputs" when there are very clearly at least EIGHT inputs -with panel printed numbering no less!- and these are not limited to only "control" but also audio.. Such may well be simply the work of someone not well versed in synths in general or this one in particular. The fact that this section contains two general purpose mixers is not even stated!

But then one reads at the end of the document that it is better to replace all transistors than to do a proper testing. WTF?! This is simply ludricrous and unconscionable for a vintage synth of this stature. If the reply sounds mad, it is. It is anger inducing to read such uninformed and misguided items at a site which is presented as a general resource. Since anger is actually fear, the fear is that others will take this bad advice and then professional techs are left to pick up the pieces, hopefully only only broken and not as is too often the case, destroyed. We all lose.

Beware following internet synth repair advice without first seeking to understand and verify the source. Quite often there will be more than one opinion, and potentially more than one reasonable solution. That's the nature of the world. Please, Please, Please make an effort to seek and discern the relative merits of disparate or competing suggestions, methods and choices.

No need to do that. It can be found at the internetarchive.org synthesizer manual section. Along with many other useful and interesting examples of important synth resources. File names are arp2500c1.pdf , arp2500c2.pdf , arp2500c3.pdf . Though the internet archive AKA wayback machine, als ohas other filetypes available for many of its synth resources.

edit: the three PDFs are also available on guitarfool's site. /edit

As was likely mentioned in other threads Sam Ecoff has a 2600 tutorial available that is really sweet:

edit - oops - thanks KSS... missed that.

There's probably more than one error in Luke's readme and I'm happy to make corrections. I haven't done a full review of the readme, I'm being paid to make the synth work. I appreciate any corrections/help reviewing his document.

That being said, I have been working with ARP 2600 owners and people who do restoration/repair of vintage synths since the beginning of this rebuild. They all know a lot more than I do and they have helped me diagnose some really wonky problems. More than one said to replace all the transistors while I'm working on a component given the failure rate of some transistors. Some of the transistors have been out of production for years, if not decades, so replacing them requires switching to contemporary transistors. ARP also changed which components it used during production and people who maintained this machine over the years have also changed/modified some components. There are at least three types/brands of wires, including patch wires, all have been added by people since 1971. The power cable is not original, it's through a new hole in the back of the case. None of the work is documented. I don't even know if these are the boards it had when it came from the factory in 1971. Even the cases are missing, why would someone dispose of those?

This not a piece for a museum this is an instrument that students should be able to use to create music. "Restoring" it to how it came from the factory is effectively impossible. Universities have limited budgets and it is more practical for me to replace all the transistors in the keyboard while I have it open instead of coming back and replacing them one-by-one when they fail and interrupt a student's work.
