I have just received notice that Mouser is shipping today about 475 new (white)
Spectrol 149 (cermet element) pots. These were ordered July 20th :(
Anyway, Indiana has been substituting 148 (conductive plastic) pots in all of
the kits (149s are needed only for the VCOs, anyway) up until today. However,
they have used up all of their 148 linear pots. The Spectrol log pots are, for
∗now∗, still black and there are 200 still not used in Indiana.
So..........
a) starting Monday, up until new 148 pots arrive, 149 pots will be used in all
of the kits for the 148 ∗linear∗
b) no, this doesn't change the sound/performance/any other possible thing you
can think up
c) I will guess the 148 pots will get here around Nov 25th, so only the very
last set of kits will use them
d) kits with the log pots (420/440/480/etc) will continue to be shipped with the
black Spectrol pots. I am ordering the new style log pots as well, but I
∗should∗ have enough to carry me to probably 95% of all the modules currently on
order
e) the arrival of the 149 pots (tomorrow) means I can ship more VCOs, but now
the pacing item becomes the tempco. These are on order, they will arrive in
mid-Nov but I have enough tempcos to ship about 2/3 of all the 300/310s on
order.
In conclusion: use the pots in your kit, they are "ok" and will work fine. Fight
through the references to 'black Spectrol pots' and the part numbering scheme
differences (the white pots have a much longer part number stamped on them).
