Chassis Discussion

No UMS HS for 3U high chassis as far as I can tell

My bad, I was thinking about he 4U/300, I'll mail modushop, thanks!

Is it really necessary to use transistor insulators (e.g. Theraterm) for the diyaudioStore heatsinks?

Any device that has exposed metal on its mounting surface must normally use an isolation pad
between it and the heat sink. The exposed metal is internally connected to a terminal of the device,
usually the collector or drain for a transistor. Since the heat sink is usually electrically grounded,
a short would be made to ground without using the isolation pad and proper mounting.
This can involve the use of shoulder washers for some packages, such as the TO-220.

I recently purchased a 4U Deluxe Aluminum and found that the cutout for the power socket was about 7mm off center. It was interesting because that the cutouts for the input and speaker connectors were within a mm of being symmetrical. One would think that with a CAD cut out everything would be off center by the same amount.

While the off centered power cutout doesn't impede operation, it is noticeable. What are my options?

Thanks,

Roy

I have, without any problem, early used Fischer's black anodised heatsinks without any isolation pads.

Been cobbling together what amounts to be a 4U mini-dissipante for a set of F6 monoblocks. Is there anyway to get 10mm front and 3mm back plates made for them? Dimensions would be the same as a 3U mini-dissipante except being 4U tall. This should be similar to the front and back plates of a 4Ux330mm Galaxy except accounting for them big ol' 4U Dissipante heatsinks.

Tom please send an email to contact@diyaudiostore.com



It is possible to do this but since it is a custom order these panels cannot be purchased from the store

I'm getting ready to order a Dissipante 2U and have some holes I'd like cutout as well as some engraving. Is it alright if I PM you my cad files to make sure I have them set up correctly?

Thanks,
Joe

Check your private messaging control panel; you might not be able to "attach" external files onto the PMs you send. I, for example, don't have this ability/permission.

Hello Joe,


You can send them directly to contact@diyaudiostore.com so I can have a look at them

Thank you!

Thanks to Gianluca and Modushop, F6 monsterblocks got some appropriate cages.

Welcome to the 4U Mini Dissipante Club.

Nicely done.

 

[6sX7]

thank you! thank you! So awesome, right!?!

 

[wcwc]

I working with the same size enclosures also. Should be done soon. I am going with a wood front and am cutting down a regular size 4U back panel to fit.

 

[tayj10]

Are there any cad files for the 3u with a similar layout to back panel of the deluxe 4u and 5u?
I wish I knew how to use cad, but I do not...

Looking good, happy to hear you are enjoying it!

If I get this right you would need the exact same holes of the Deluxe 4U rear panel Deluxe 4U Aluminum – diyAudio Store but for a Dissipante 3U chassis? If that's the case, send an email to contact@diyaudiostore.com and I'll show you how to place your order for this

I placed an order for a 5U Deluxe Steel on the 30th. I have an immediate DIY receipt of order but nothing about a shipment yet. That's the order day plus two business days to push it out the door. I know it's Italy and they have MANY holidays, but is this normal?
