Gb: F5 Pcb

Re: Re: Re: Re: Re: heatsinks

LabJR,
I have the Surplus heatsinks we discussed earlier running with the PD F5 board. 3-4 hours and I can still grab the heatsink for a long time. The conrads (I have four of these now) I think are overkill for F5. The surplus heatsinks I have are ~13" X 7 1/2" X 1" fins (sorry for english measurements).
This weekend should be warm, so I will crank the house heat to 75F and run normal bias and let it run all day to see if it will have some room to run in the summer.
As we calculated earlier, these are .50 c/w sinks. If it's close, I will glue a bunch of PC heatsinks on the inside, since the board itself takes so little room.

So you're using the Conrads or the surplus ones?

Using the Surplus ones. Saving the Conrads for future F3 build.

Check it out.

And yet another set of F5 pcbs arrived at their destination in great shape.

Thanx Christian.

Just want to thank cviller for the GB. The board arrived in good shape. Now is time to hunt a good pair of good heatsinks for them.

I cant find any spacers with a built in bottom screw, just like a motherboard spacer. Looking for M3 size but i cant find them anywhere! I probably dont know the proper name.

Hi,

I would build an f5 amp: are still available f5 pcbs and psu pcbs?

Needed a couple as main board as psu. Will buy with paypal.

Anto

 

[cviller]

Yes I still have boards available. Just mail me or paypal me with your order.

 

[bobodioulasso]

I just received my boards. Thanks Cviller, you were fast and the boards are nice.

Here is an example on how you could choose to wire the F5. I have intentionally left out the mains wiring part because that is very nicely described in the F5 article and I don't want to be blamed for any house fires...

Could you point me to the F5 article?

Thank you very much.

Note that there are still two pairs of Conrad heat sinks left on ebay.
