CRC Power Supply (Class A amplifier)

[manniraj]

Is it possible to use this board with off board caps so that we can use 8 or more caps? Looks difficult for me but not sure as never tried off board caps especially for power amps.

thanks

Yes you could use off board caps after the crc pcb

Thanks Prasi, if I understand you I can take the DC output (+ / -) from the PSU and connect to the external cap bank and from there I can connect to the amp boards right? This way I still will have the flexibility of maximum capacitance for a class A amplifier without effecting anything else in the chain!

yes, I think you should move the ground connection(of amp and other aux circuits) too to the o/p side of your new capacitor bank. read the recommendation from Bonsai on hifisonix site.

I bet it took you some hours trying to draw twisted wire

No sir!, that hard work was done by bonsai, DIYA former member

prasi,

You can mark me as delivered. The boards arrive in perfect condition. Nice and think with plenty of room for big caps.

Hi
I just found these GB, I would be interested to get 4pc off these PC board for a fair price and shipping to Toronto Canada
Please PM me and let me know the price with shipping cost so I can decide (if I can afford it) to place my order. I see some other thread for N American DIY-ers?
Thank you
Greetings gabor

Hello Gabor,
Thank you for your interest.
As far as I know this is the only thread where GB is happening. Only initially pinnocchio had done a limited GB for Canada.
I will send a pm to you.
Regards
Prasi

Hi Prasi
You got the payment and sent you an e-mail. It would be great if you could read it before you ship.
Thank you very much! for the early
