Don't quote me but usually it was something like ~$16 extra depending on the size of the box/tub used.

IIRC it was more than that. I think the price was at least $25 higher when I ordered a potted/shielded unit compared to "stock". There's also typically a longer production time for the potted trafos, in case that matters.

Yep, it was $20 to to shield/encapsulate the 30VA models so $16 is low-balling it.

The base transformer also costs a bit more than, say, an Avel Lindberg equivalent...... but I'm still very happy with the results

yup, $91 with shipping for my encapsulated 30+30V 80mA to MN. it took about 2.5 wk from ordering to doorstep.

80mA?

you mean VA.

Here are a couple more pictures of the case that DoYouRight requested. It is a beautiful case, the pictures do not do it any justice. I am also using the 2mm aluminium top and bottom panels.

They are nice cases. Galaxie, if I'm not mistaken. I used one but smaller for my σ22 PSU.

doh

[DoYouRight]

they look nicer than the parmetal, why dont more people use them if they go all the way with FPE and stuff?

Unless you live in Italy they can be quite expensive with shipping. I bought one for an S22 I built and I like it a lot, but my B22 and next S22 will be in Par Metal cases.

WHY are they so expensive? they don't *look* expensive to make. what's up with this?

I understand shipping is a lot. but the base units, boxes just seem so simple to make. is it mostly mark-up that accounts for the price? the fact that its a small market or limited interest market? lack of competition?

They are made of thick aluminum. Par metal enclosures are quite thin and still aren't what I would call "cheap". Also this shipping cost can be more then the chassis it self.

I reckon the par metal cases are a better, stronger design. The hi fi 2000 cases have a very annoying arrangement for top and bottom panels, only 4 tiny screws to hold a lot of weight.

 

[DoYouRight]

but the side panels are wicked!

I got a question guys. Now that my parts for the 4 Beta22 boards and 2 Sigma22 boards have been ordered (the machining of the case is going to be a whole different animal because it's going to be completely custom machined and lasered based on parts from a high-end amp and preamp manufacturer, 5/8" thick front panels), I need to know about gain.

Will the default gain of 8 be enough to drive the HD800 to very loud levels and/or have plenty of headroom? We have figured out that it will drive a 300 ohm load to about 666mW and a 600 ohm load to 333mW. This seems more than enough considering the HD800 is rated at 500 mW. I just wanted to make sure, even though I'm not going to be listening at extremely loud levels. I don't want to add unnecessary gain which can increase the noise levels if I don't need to.
