BOSOZ Chassis Construction

LizardBrain · 15th March 2006, 06:18 PM

I am about to begin building the BOSOZ and I have a few questions about chassis construction.

I will be building my own chassis for the preamp out of wood or a combination of wood and a metal frame. I have read here that an all wood frame is fine. Yes?

My question is: What is the advantage to putting the preamps in different boxes than the power supplies. I understand the distortion issues and such. But, if I have the means and ability to build two or three chassises, separating out parts that don't always play together nicely, is this:

1. highly advisable
2. somewhat advisable
3. probably won't make that much difference in the end

And, how best should I separate the parts?

Thanks for the help. This will be my first build and... as they say "well begun is half done."

The best reason for putting the power supply in another box is to keep the transformer far away from the signal wiring.

Agreeing with eLarson. If you can afford the additonal hardware and space, I would say it is "1. highly advisable". I like putting half of the 'pi' in the separate basket

Where do ya'll who buy them, buy your chassis for your amps and preamps?

I got my cases from group buy here. I think some people have been mentioning Par Metal as a good source for the case: http://www.par-metal.com/
There is also Front Panel Express, where you could design and order aluminum panels to be cut and drilled by your design for very reasonable price. Separate case for the PS is good in order to separate transformer from the signal wiring, but if you have enough space you can make metal deviders for the transformer which will do good job as well. Here are my images for two case XBosoz:
