Notes:

1) The J112 is pinned (flat facing view) as D S G whereas the board pads use the 2N3819's D G S order. Placing the J112

is simple enough: the flat side should face the 10 o'clock direction as the leads go into their respective pads as noted on the

silk screen.

Errata for rev1: (rev2 builders can skip these)

Refdes swaps:

R45 and R65, values are correct

R51 and R55 (values correct)

R80 and R160 (values correct)

Value changes:

R154 is 10K, board is marked 1K

R155 is 4K7, board is marked 10K

R33 is 47K, board marked 100K

Swap R34 and R35 values: R34 is now 27K, R35 is 100K

R84 is 150K, board is marked 100K

Additions:

Add 1N4148, anode to IC13 pin 1, cathode to IC15 pin 16 (clamp diode)

Errata for rev 2: (rev 2 builders take note)

When building for 1-4 voices using a carrier board, omit the following parts from the host board:

C32, C43, C44, C45

D1 through D6

R44, R45, R46, R47, R48, R49, R50, R51, R52, R53, R54, R55, R56, R57, R65

R136, R137, R144, R145, R148

IC5, IC9, IC19

J1, JP1, JP2, JP11

L1, L2

Similarly, install these parts on host board when using a carrier board:

R164, R165, R166

OSC1/OSC2 FM fix: resistors R93 and R94 need to be cross-wired to correct a minor oversight where the switches for

OSC1 FM and OSC2 FM were in fact affecting the opposing VCO. (FM1 switch was modulating OSC2, etc). The easiest

fix is to install R93 and R94 as shown here (820K resistor from R93 left pad to R94 right pad, another 820K resistor from

R94 left pad to R93 right pad using wire insulation on the resistor leads):

FINAL:
