I powered my ASM-1 up last night...

Oh no, not smoke! I would guess that it was probably one of the two 22
ohm resistors at the top end of the noise generator section (near the
VCF).
These two resistors are used in a pair of simple R/C filters on the +
and - power supply voltages to the noise gen (this is to reduce supply
hum in the noise hi-gain amps). If you have a bad or backwards
(shorted) 10uF cap on these filters then a resistor will smoke.
The MAT-02 has a little tab on one side - this should be away from the
V/OCT trimmer.
Good luck!

... and a resistor smoked on the noise generator... no big deal... but
both my oscillators are silent. I am checking with data sheets my
transistor placement, but I can't find a MAT-02 data sheet.
I took a chance and dropped these things in the way they looked like
they were suppose to go, with the 3 wires on each side of the can matching
up with the 3 holes in the board. Is this right? If not, can someone
explain the orientation of the MAT-02s on their board?
