chassis mount power jacks: 13mm vs 8mm

[peterg]

Other than taking up less internal space why are 13mm chassis jacks instead of 8mm chassis jacks  used in boutique and diy stompboxes?

Hi Peter, Just guessing as to the types you are refering to but the 13mm i believe are the typical easily available switched jack that allows also using a battery inside the pedal but disconnects it when a power plug is engaged. The 8mm, again guessing as to the particular jack, doesn't have the switching capacity so is used for pedals with no internal battery, not as easily sourced but that is improving.

Shoot!!... where are those 8mm jacks available at? I never use batteries, and the smaller size is really appealing.

I'm amazed that I haven't seen them before.

In the US, Small Bear, recently to me, added them, bitcheslovemyswitches, I think someone had a Jameson Jameco part number as well.

This might be similar to the one you posted. This one has a switch.

Thanks for the link.

I'm with Dino on the "no battery" thing. I have not built one stompbox that takes a battery.
I think it harkens back to the days when I was just a singer. I recall the guitar player scrounging around for enough money to buy a 9 volt battery for one of his effects. (on the night of a show, at the last minute!)
With all the production/DIY pedal power available these days, the price of 9 volt batteries on the fly, and my obsession with fitting large circuits in small enclosures, IMHO it just doesn't make sense to include provisions for a battery.

I tried 8mm jacks on a few builds lately (Brian specced 'em for the Zero Point, so I grabbed 10 while I was at it for the discount), and they don't feel as nice as the 12.5mm ones, kinda 'rasps' as you put the connector in.

It's a toss up between vertical room (8mm, it sticks out into the enclosure but presents a small footprint in the side of the metal) or horizontal (the 12.5mm takes up a big hole, but doesn't stick in as much as the other.)

That's going to depend on the style of the larger type, external nut doesn't take up much  room internally but the internal nut setup (more common/preferred?) eats up a big chunk of real estate.

I've only used the exterior nut 13mm type.  I put a nut on the jack before installing it and adjust it so the the exterior nut and plastic face are flush with each other.I like the option of removing the harness from the case without desoldering. How do the 8mm jacks compare with pc mount jacks re interior space?

BLMS sells those small ones cheap.  I got a bunch from them for my 1590a builds
