The diyAudio Firstwatt F6

Conrad heatsinks (Australia) appear to be having an August special. Their 35-151.5, with .21 C/Watt, are usually $53Au and are now $38AU. Here is the quote I received:

MF35-151.5 x 2 @ 38.34 ea. 76.68 (71.01USD)
Delivery 5.4 kg (Aus. Post Sea Freight 10 - 12 weeks) 25.00 (23.15)
Delivery (Aus. Post Standard Air 7-12 working days) 35.00 (32.41)

(Hopefully that's useful and is well on the safe side for use in an F6...there appears to have been a DIYaudio GB a few years ago for use in a similar amp.)
