D1 I/V questions

was ist los? · 18th November 2003, 03:06 AM

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?

Why not use 30V psu from bosoz?

Could i use a 2x30v transformer?

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

Has anyone tried the D1 I/V after the TDA 1541 ?

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.
