Hello Salvo,
Yes, definitely its possible to order PCB from me.
Please share your complete name, postal address, postal code and paypal address by private message to me(just click my user name and choose the " send a private message to prasi" option). I will then send you an invoice through paypal, against which you can make payment. I will then ship the PCB's to you via a tracked shipping service thats very economical.

The sales through diyaudiocart is for Indian diyer's only. I will be taking care of all International needs for this PCB.

since you posted your email address, I will shortly send a paypal invoice to you. Please make the payment and share your details as per above, and we have a deal🙂.

regards
Prasi

P.S. You might already be aware of this information, but Posting this info for the benefit of others.🙂

edit: invoice sent.

Hi Prasi,

Many thanks for all your efforts, I have finally received the PCBs!! Now to start the assembly process. Still need to finish off the amps, but that is not a train smash, as I have the components at hand for them.

GB VII officially started with me getting a flurry of requests for PCB by PM. Fortunately I had ordered a batch of 50 PCBs to cater to the sporadic requirements all year through.
I have about 54 PCBs as of today and already 16 consumed...
DIYA Member thro PM 6 boards
DIYA Member thro PM 6 boards
DIYA Member thro PM 4 boards

So 38 more remain of the 5 pin caps CRC PSU pcbs.

I also have about 5 PCBs from the first GB with 4 pin caps. I am willing to give away these at 25 USD+Paypal+S&H. Let me know if anyone is interested.

regards
Prasi

Hello Prasi,
To get airflow up through the rectifier heatsinks, could I drill a few strategically placed holes?

Hello Vunce,
Yes you could, but take care not to thin out traces above or below.. Also you could use kapton tape (2 layers) over places where heatsink is likely to touch the pcb. grey area as shown.

Hi Vunce,
The MUR880, for example has a max operational temp rating of 175C. If you are running at say, 65C or 70C even, probably no big deal. Mine are at 65C and I am not going to lose sleep over it. 🙂

You’re probably right X, the rectifiers I’m using are rated to 150°C . Since there is a third output on the PWM fan controller, adding a fan would not be a problem if I lose sleep over it, LOL 🙂
