Power entry advice

[kineteks]

I'm building a trio of TWs LP, EX & Rocket and am using Allyn's excellent chassis. His power entry is "TW style" cord in with a strain relief grommet, and I'd like to use a screw-mounted IEC power entry module. The problem is the hole spacing on Allyn's chassis doesn't really allow for the IEC PE module to be placed to the right of the fuse holder (looking from the back of the amp). The required cut-out would put the PE module at the extreme outside edge of the chassis and hard up against the fuse holder. Would there be any functional issues with swapping the fuse holder and PE module positions? Fuse on the outside (existing pwr cord entry hole) & PE module just to it's left (again looking at the amp from the back).

I'm not familiar with that exact chassis but here's a pic of what I did with a Ceriatone chassis. I used the fused IEC and then used the regular fuse holder for an HT fuse. You can see in the bottom pic how it's a tight fit with the rear panel for the cab but it fit/worked...and I don't think you'd even have that issue with a 'traditional' TW-type cab.

The Schurter 6100.3100 is 48 mm wide and will just fit as I said, it'll touch the fuse holder and be right at the edge of the chassis. If swapping the positions of the PE module and the fuse holder is not a good idea I'll probably just go "old school" and do the power cord strain relief thing. I just don't care for the way it'll look jammed together like that...

it won't hurt anything to switch

[gearhead]

Or you can do what I've seen others do, which I adopted. Rotate the IEC socket 45 degrees.

[drhulsey]

Better, yet– 90 degrees And, yes, it's a tight fit

Apex Jr. has an IEC socket with an integral fuse holder...

Tim did you use one of Allyn's chasis? I have his liverpool chasis and notice this same problem a few days ago. Since I was uing the BOM I ordered the IEC socket and cord not even thinking that Allyn's chasis has the round strain relief hole.

There's another version of the socket out there that doesn't require the bolts. I used one of these on one of my TWs and then the other type on the other. It has these tangs/grippers that compress and then spring outward to catch the chassis. It is very stable, in fact. I literally pulled the tangs out quite beyond the hole edges to totally secure it. It is not coming out of there and my point is, it is narrower than the type you have and fits very well next to the fuse. Mouser has to have it?

But yeah, when I picked up the bolt in type it was super tight. I actually filed down the widest edge to make it fit next to the fuse. It was goofy work somehow but git'r done takes over sometimes................. Eh, it looks fine.

Yes, it's Allyn's chassis. I cut out the hole to fit the IEC. I used small machine screws to hold it in. I had to grind off a portion of the lower nut to make it fit. As a friend of mine once said, "If it was easy, everybody would be doin' it!"
A detachable power cord is so-o-o much more convenient, IMHO. And, yes, I do keep an extra one close by

Yup! For whatever reason whenever replacement computer equipment arrives at my office with an IEC power cord, the old one gets re-used and the new one disappears

This is what I'm doing. Works fine.

[M Fowler]

I looked at it carefully last night and I will put it on a 45 degree angle as Skyboltone suggested, I want to go with the IEC socket. Thanks guys your ideas helped a lot.

Well I got the dremel out and made a pattern an cut the opening at a 45 angle and drilled my holes. This idea worked very well, thanks guys.

I recently sent Allyn a message about which cords and strain relief he uses so I can go that route in another build. Need part numbers as my eyes went crazy looking through the catalogs.
