Default D1 I/V questions

Hi, i'm new and have some stupid questions. I have a few questions for just the I/V of the D1. What is a good +/-30v PSU for it?
What if any heatsinks do i use for the mosfets?

Hi,

Have a look in the service-manual of the D1Link
When completed you can decide to use heatsinks or not.
I've never build the thing, but don't think it is needed.

Regards,
Remco.

Hi, i actually have looked at the manual and am confused. There is a +/-30 volt PS and a +/-15v PS with a follower that outputs +/-30v. Which do i use?

Hi,

I think you need this power supply:
(see attachment)

Specs of transformer:
1x30V.. 50VA.. or higher..
You can improve it, but I think it is enough for it's purpose.
Anyone tuned it?

Regards,
Remco Blankesteijn.

Yes, you can.
You have to use less zeners.
Read the bosoz article for further info.

You think using the BOSOZ psu should provide better result that the original D1 psu?

Hi,

The D1 psu is cheaper with less components.
The Bosoz has more components, but I think it will perform better.
If your rig is Passlabs, why not put everywhere an IRF(9)610 instead of an regular 7815.

Regards,
Remco Blankesteijn.
