BMC - FM Drum - build notes

BMC25. FM Drum

 F

 sTART WITH the lowest profile components ..
usually IC sockets , resistors , etc

These are personal build notes just to help me trouble shoot should I have any probs.

 As it turned out, this was a easy build.

cAPS next

the BOM calls for these:
0.002uf 1 Poly box type.  ... 2nf  or 2000pF
I'm using a 2.2nF cap

0.02uf 1 Poly box type ...20nF or 20000pF
I'm usinh a 22nF cap instead

.01uf 7 cheap ceramic disk....10nF (103)

 sWITCHES  next ... not sure how the panel and PCB link ??

i decided to install the jacks , switches first.. Then it became apparent the the panel is held to the PCB by the pots.

Solder the pots to the PCB.

 Time for the sole LED

Jacks:
IN - tip of the input jack
CV - tip of the CV jack
OUT - tip of the output jack and switch of the CV jack to allow self modulation

Modulation Waveform Selection switch:
MS - Top lug of switch
MC - Center lug of switch
MT - Bottom lug of switch

Output Waveform Selection Switch:
OS - Top lug of switch
OC - Center lug of switch
OT - Bottom lug of switch

For a ground connection, use the center wirepad of whichever power supply you're not using.

Nice !!!
