I don't remember seeing these cases on Par-metal's site... but, was wondering if anyone has used them.  Here's a link:
http://www.par-metal.com/20series.htm

I was thinking 16"W x 16"L x 4H" would work for the 100 but, I haven't measured yet.

I have a nice chassis but it's warped in such a way that nothing lines up.  And it's too hard to bend back.  Plus, I want it to look as good as it sounds.  I'll be doing some upgrades to the electronics soon and thought it was a good time to move it into a new case.

So, any opinions on this one or suggestions for another one?

Thanks,
Carl

These cases actually look very promising and reasonably priced, and you can funk them up a bit with thick front panels (.25" or .375") in black/gold/anodized.  

I'm waiting on detailed pricing with thick fronts and internal dividers, but these look like the answer to my prayers from a metalworking perspective

Hugh I'm wondering if a 4" high chassis would be enough for a GK-1R?

[AKSA]

Yup, you can actually get away with a 3" high case for the GK-1R if you are careful and mount the tubes visible on top.....

Carl, surely you can bend back the case?  Pull it apart and give it a good hiding, you'll get it in place, or take it to an auto panel shop, then have it repowder coated?

Cheers,

Hugh

When you tilt the pcb with the tubes 90 degrees, would that meake a difference?

Hi Kyrill,

How are you?  Building well?

When you tilt the pcb, you are restricted by its 'width', which is 80mm.  Therefore you need about 85mm all up.

Doggone.............

Hi Hugh

I could not analyse the width from the pictures.

I have actually finished soldering the pcb's except from the big (power) transisitors attached to the heatsink as I am finishing  the best "inner" place for the heatsink. I found a "new" inner  configuration, at least  I have not met it yet published on this forum and of course I think it has its "unique" advantages  

I am still in doubt what to do with the leds. one or 4?

Is it not possible to have one led connected to the primary side of the transformer with a suitable R? I know it is not dc but the 50 hz cycle (in Holland it is 230V 50 hz)will not make the led into a disco flickering device . Or will I endanger the delicate balance of the power supply as well?

the pws has no bypass caps just before or after the bridges fo HF filtering like 100nF or so.  I see one rc circuit in the primary department. will it  have a negative effect on the sound to add a couple of 100nF  in the secondary department, or is it just not  "hearable" ? (just curious : )

[ghamel]

Head, (can I call you that? )

Thanks for posting the Par-Metal pics, they look fabulous, much better than the pics on the webite.

Did you do anything custom to the cases, ie substitute flush mount screws, etc?  The case on the website looks like they use butt ugly cap screws, and the ordering links don't show the ventilation holes on the top, so I'll take your advice and be overly precise when ordering  

Do you happen to have any more pics of the top/sides of your lovely headphone amp?

Thanks,
Greg

Unfortunately, the cases aren't my personal handiwork, I just thought I would post them so you guys could see :p

About Par metal, they say you gotta be VERY SPECIFIC in everything you ask for because if you don't specify exactly what you want, you may not get it.  Someone ordered 3 cases from them and the parameters that weren't specified precisely were different on the 3 cases, though one might have assumed that if I ordered "3 cases of model XX" they would all be identical.

1. Their paint job is no good, so it's best to ask for all anodized.  You can mix and match front panel and the rest of the case.  

2.  You have to ask for the screws to be countersunk.

Dear Hugh,

How difficult is it to fit the GK1-R into the 2U case that you wrote to me about?  I thought that the height of the case was 88mm which I presume is external height - minus thickness of walls and bulging of plates, this could get might close to 80 mm width of the circuit board.  

Does the Circuit board have a lot of stuff which has to come off parallel to the board, or can it be oriented reasonably easily with connection coming off perpendicular to the board?

Given my near zero experience with metalwork, would a 3U case be easier or "better"?  

With thanks,
Mark W.

PS I am going to have to buy something from you soon

I am waiting the arrival of the GK1R
In the meantime I thought I'd get a head start and  build a custom handmade polished copper and aluminum case for it. I am now at the point of cutting the valve holes in the top . Can someone please tell me what the distance is {centre to centre} between the two tubes? It looks like about 10 cm. but I can"t be sure

Thanks Paul

[AKSA]

Paul,

Distance centre to centre is 69.5mm exactly........

Hope this is helpful, and pray it all arrives soon!    

Cheers,

Hugh

[Snapper]

Does anyone know of an Australian company building custom cases like Par-Metal's?

Hugh,

what is the physical size of the GK1M & TLP main board?
Also, what is the hight of the supplied transformer for GK1M & TLP? I am thinking of a double compartment case where the transformer stay at the bottom.

Just had an hour listening to my uncomplete AKSA100n. Well, it lay naked on the table without any cover or case. Although it have little time to break in, it already sound very good. Can't wait for my 100R and 270R Ohmit resistor to arrive so that I can finish it off and place the AKSA100n into the case.

Cheers,
Sam

Hi Sam,

Also, what is the hight of the supplied transformer for GK1M & TLP? I am thinking of a double compartment case where the transformer stay at the bottom.

GK1 analog pcb:  267mm x 80mm
GK1-M input/output switch board:  232mm x 54mm
TLP pcb:  84mm x 66mm

Height of transformer for GK1:   50mm

Hope this is helpful,

Cheers,

Hugh
