Power Amp PSU Board (for e.g. LYNX Amp)

Just wondering, how thick pcb is preferable? 1.6, 2.0 or 2.4 mm? Personally I think it would be good with a bit thicker pcb, like 2.0 mm.

I think the new lead free component has a part number of 531302B02500.

Hi P-A,

One last question before I join the group buy, where can I find the specification of the heatsink 6100BG Aavid? Sometimes it may be extremely difficult to locate suitable heatsinks for putting onto a custom-made PCB.

Thanks.

Jim

The part I've listed is RoHS, it says so at least. Green dot is RoHS, red triangle is not.

P-A
My preference is for 2mm minimum.
Wiki updated to include my boards.
Thanks!

Screwholes

Screwhole diameter:

Size M3 => 3.5 mm 0.1378" Is that OK?

I would prefer 2.4 mm, 2.0 mm minimum.

I'm in for 2 boards. Wiki updated.

2 boards added to wiki. sent contact info to peranders.


Thanks for the efforts!!

Prel. dimensions of the board is 7.2 x 8 ".

Per,

Maybe it has already be asked, but what is the diameter and pitch of the snap in type eletrolytics?

I'm thinking that 40mm diameter is the best way to go - IMHO

Total is 122.

 

[JimT]

Board thickness: 2mm is fine

Screw holes: M3 is fine

Prel. dimensions of the board is 7.2 x 8 ".

Please confirm the dimensions as the 7.2" seems too wide.

Thanks
Jim

Jim, 4 x 40 mm caps = 170-180 mm With the caps in a row you'll get a different shape but if you'll have some max dimensions, let me hear it.

Is it necessary with 4 caps per rail? Double rectifiers need 170 mm if they are place vertically.

Jens, BHC 15000 uF / 63 V Regular 10 mm snap-in will also fit.

 

[peranders]

If I use Jan's layout I'll get 300-320 mm and 100 mm wide.

 

[JimT]

Actually now that I think about it, 7.2" * 8" is probably a better size for me than the original 3.55"x11". Thanks for your efforts.

Same here...

The pcb is rather universal and the disadvantage is a bit larger board if you'll don't need all fetaures. Is series inductor/resistor really necessary? How many vote for this feature?

 

[AndrewT]

57sqin is far too big.
Find a way to make the PCB much smaller.

The layout

Prel. layout, only the placement. I have not made any routing.

[peranders]

Andrew, what do you need in terms of specifications?

 

[SvErD]

I'd prefer to loose the rail fuses and the bleeders.
I never use rail fuses in poweramps
If you want bleeders they can be soldered to the bottom of the board in the unused capacitor holes.
