ARP 2600 patch cords / jack size?

AntManBee
So I read that the ARP 2600 used Tini-Jax sockets, although I also
read that ARP made a change to better jack sockets when the 2601 was
introduced in about 1976 (which is the model I have).

I have loads of Ad Infinitum 1/8" patch cords for my euro modular,
which seem to be fine if slightly loose in my 2600, but is there
currently a source of patch cords specifically for the 2600 which use
Tini-Jax (which I believe are slighlty larger than 1/8"), and is there
any reason to use them with the 2600 instead of the Ad Infinitum?
CAESound has some 'ARP 2600' patch cords listed on their site but only
in long lengths. What are you ARP 2600 owners using?

hi Matt,

i am using normal minijack patchcords with my ARP-2600. they work fine.
ok they might be a bit loose sometimes, but they work really fine.

even with the Buchla 200e, that is using tini-jax for sure, i am still using
normal minijack patchcords without any problems at all.

Is this just due to the difference between English and Metric? I see  
that Mouser lists 3.5 mm as the metric size, but if you do the  
conversion from 1/8" you get 3.175 mm. That makes it seem like a true  
metric jack at 3.5 mm would be slightly larger than a true  
1/8" (3.175 mm) hardware.

... or does anyone actually make true 1/8" hardware?

headphone-related stuff.

I suspect that a larger problem in the world of 1/8 jacks, is the shape of
the tip of the plug.

Wow, I hadn't ever really appreciated how big a difference that is - the
3.5mm jack is over 10% bigger than the 1/8", which seems too big for
reliable inter-changeability.
Not sure what the gap between plug and socket is supposed to be, ideally...
but there are definitely varying standards.
I just bought some RCA-1/4" adaptors to feed some stuff into the main
channels of a Mackie CR-1604VLZ, and they simply don't fit.

I use roland 100m patch cables
they are OK

Hi Matt,

Ad Infinitums work fine in the 2600's Switchcraft Tini-Jax. There is
no problem using them. Tini-Jax are.141" diameter, not 1/8". Be
careful using Tini-Jax Plugs with 3.5mm jacks. Although there is only
a very small difference in diameter between them at .141 and 3.5mm at
supposedly .138dia., it is enough to cause failure in the normal
switching of some brands of 3.5mm jacks. Tini-Jax Plugs will not
insert at all into some 3.5mm jacks, and will definitely not fit true
1/8" jacks . This has been true for a long time and is unrelated to
the recent discussions about the switch failure of certain Chinese
3.5mm jacks. Tini-Jax plugs would certainly make that situation worse.
Don't use old 2600 Patchcords with your Euro Rig! Buchla also uses
Tini-Jax patchcords, so be careful of using those with 3.5mm jacks
too.

As Paul Perry wrote, the tip shape is very important, Also tip length,
which early Cwejman S1 users will appreciate. Some plugs have tips
long enough to touch the PCB and short any traces running under the
pcb mounted jack center. Ad Infinitums do not have this problem. In
the 70's and 80's, there used to be a lot of variations in the then
new smaller jacks and different manufacturers were not compatible..But
since everything was referred to as 1/8" Jacks, the variations were
not always noticed or accounted for and both baby and bathwater were
lost when things didn't work as expected. I believe that many minijack
haters are a result of the variety of tip shapes and sleeve diameters
used and expected in vintage so-called 1/8" jacks and plugs. Add in
the true 1/8" jacks, which are a third size and its no wonder there
were and sometimes still are problems.

As for the change to better jacks in the later 2600's, Tini-Jax were
still used. The change was to go from the PCB mount type to an open
panel mount type, due to field failures in the normals of the closed
PCB mount style. This is due to the contact being a shaped spring wire
which can be displaced from its ideal position during soldering. A
service bulletin was sent out by ARP to fix this problem by
re-soldering and using a bit of wire to get the right height spacing.
But ultimately, ARP chose to re-design the PCB's to use the open style
Tini-Jax for any normaled input. The PCB mount Tini-Jax were kept on
Outputs.

Cheers, Roger

Hi Matt,
curious, why you didn't ask where I posted this info? Why not discuss on
Muff's?

I meant, ask on the thread you saw it on.  Happy to share details. most
3.5mm work with the 2600, however, those tini-jax may destroy euro and other
3.5mm jacks. is there a 1/8" that exists? I bet it does but did anything
actually use a truly 1/8" jack? 1/4" is 6.5mm  has that changed. Why NOT use
METRIC????

i have been using a set of yellow korg 'fake' patch cab;es on my 2600 and it seems happy.

also cheap 1/8th inchers from china that make contact ok.

maybe the sockets are old and tired...
