prasi, boards received.


Many thanks.

Hello all,
Thanks a lot for the overwhelming interest shown.

I was wondering if people would be interested in a dual supply based on lt4320 in a crc configuration with 40 mm dia caps?
All of course done with THT parts.

Yes!

 

[prasi]

Yes!

thanks rinman for the prompt interest,
I would like to gather atleast 50 pcb worth of interest before i can consider it as a GB.
So come on people...I would like to see some numbers...

@prasi, there is a chance to provide full B.O.M in the G.B.?

 

[prasi]

Sure merlin. I will do a full bom.

 

[merlin el mago]

How much will cost each full kit without pcb?

 

[prasi]

Sorry Merlin, I must have misunderstood you.
I am not going to include parts in the GB. Only the PCBs.
Parts will have to be arranged by GB subscribers.
By bom, i meant, a mouser list of parts in MS excel.

Prasi

when you say "dual supply," do you mean a positive and negative supply, or do you mean dual mono supply that can be positive/negative or positive/positive?

 

[prasi]

yes, +/0/- supply.

 

[prasi]

here is the daft design.

[merlin el mago]

No problem prasi, thanks for the GB for boards I will order the B.O.M. to Mouser.

Have a nice week-end

Hi Prasi,
The design of the new board looks promising so far.

I would like to suggest that the output RC snubber be arranged so the capacitor may be an electrolytic type with 5 mm lead spacing and up to 12.6 mm body diameter. I have found that the CRCRC PSU that I am using sounds better with a high-quality 1000 uF capacitor in parallel with the last bank. For the larger bank capacitors of 27,000 uF and higher, which this new board will be using, the inductance is high enough to affect the audio performance. The simple way to fix this is to add smaller value caps in parallel with the big 40 mm caps.
