Lex,
So is Michael sending you a replacement board?  I'd recommend swapping
out the old one.  The added power from the new board provides a lot
more control over your roast.
As far as profiles go I'm still working on getting experience with my
newly converted HT-B.  I'm shooting for 15-20F/min ramp to start of
first and then about 3 min to start of second.  In terms of the
settings for the fan and the heater, I start with the fan off, at 3
min run the fan at 25%, at 7 min increase to 50% fan, at 12 min
increase to 75% fan and then 100% fan at first crack.  The heater
starts at 100% and I drop it to 90% at the 12 min mark (1 min before
first), decrease to 80% at first crack, then decrease by 10% each
minute (still working out the details here).  This is loosely based on
a profile that Mike Chester posted here a few weeks ago.
I roasted four batches of Tanzania Ngorongoro to FC with this profile
last weekend.  First crack was within fifteen seconds of 13 min each
time and I stopped the roast just at second crack between 16-17 min
total.  I've been enjoying this roast this week.  My roasts of this
coffee before the upgrade weren't very good.  I also roasted up some
Monkey with the same profile and it will hit the grinder this weekend.
 Looking forward to tasting the difference from the upgrade.
Hope that helps,
Cameron
