Good to know. I was thinking about a bit bigger one: 504222B00000G Aavid Thermalloy | Mouser Ireland It seems just about to fit so I guess I'll stay with it.

Either of those heatsinks will work nicely. All that matters is that the mosfet have something.

Does anyone foresee any problems?

I'm using the AMB Labs Sigma 22 in my BA3. Some may say over kill but it looks cool.

Thanks budweiser. I am looking forward to building the preamp and the amp. Just ordering parts now. Some goodies should be coming from the DIY store in the next week or so.

Default Need a volume control?I

I am looking to build the BA3 ( as a pre) driven by my DAC (Buffalo 2 + Legato I/V) which has a volume control. Can I forego a volume control on the BA3? Amps downstream could be the MoFo, VFet2 or F3

As always - thanks

Yes you could, but if you ever changed your sources you may find yourself wanting volume.

You could also have a set of inputs that bypassed the volume if you wanted, or set in a switch that bypassed it...
