KM84 DIY Body & PCB kit – CLOSED

[Andre]

I should have noted that I received my kits in New Orleans a week or so ago.  They were packed very nicely.  I'm quite impressed by the whole thing.  Now I'd just like to hear them.  The boards are stuffed but Im waiting on transformers from Cinemag.

Edit: never mind. False alarm. Thought I had messed with the BOM project, but I checked in another browser and it's fine.

Hey Banzai, Graeme...

Just to  let you guys know,  mine also arrived safely, a week or so back. 

As soon as I've finished this album project, I will get straight onto the build!

One question (probably I should ask in the build thread, too):  The brass bodies have quite a few stain marks/tarnish .  What is the preferred method for polishing those marks off.  I'd rather not sand, if possible, as I like the polished brass, and don't like the idea of spray painting these for fear of upsetting the width of the slot gaps behind the capsule. Clearcoat alone would probably flake off eventually.  I'd just like to be able to clean and polish them..  Would something like brasso liquid to clean, followed by turtle wax to finish, do the job, do you think?  Or has anyone got any good ideas...

Many thanks again for this excellent project!

nEon.

Unfinished brass naturally tarnishes. You can use a polish, but I think the idea for is to have it painted. Otherwise you would have to apply polish every time you handled them.

Thanks!

Thanks for your thoughts Paul. 

I have lots of paints in stock, but I'm not sure that even a well primed, painted and lacquered mic will stand up to the rigors of repeated insertion into mic clips, over time..

Never tried it before, but I'm thinking this may be a good time to check out a local powder coating setup. Got a custom tyre place nearby, who do powder coating, so I think I'll check 'em out for a quote.

Thanks again,

nEon.

It cost $20usd to get 2 tubes powder coated, that seemed to be the average quote when I called around (California)

Thanks BramK,  that's a good price gauge! much appreciated. 

I'm in North London, and these local guys specialise in fancy colours for wheels, mostly.  Bigger items.  I just hope they are capable of handling something much smaller and delicate.  Let's see..

Also in north London (well, north-east) so please do let us know what you find! I’ve googled a couple of powdercoat places in Tottenham, haven’t approached them yet - happy to feed back if useful.

Will do!

Wish I had known that before I sprayed mine. I spent close to that on just the paint.

Hi guys,

I'm trying to install the gzt transformers but they don't really fit. Any tips?

You have to sand the edges of the hole. I used  a Dremel, a file works too. Just be sure you don't cut the traces!

Hello Banzai,
any chance you will do another batch of the KM84 kits?

Thanks

I'm curious as well.  I’d love to build a pair of these.

Thanks!

Who's Graeme? Is it going to be a GZ capsule? 127C flat?
