Oakley Parts - VCO page – Revised 04/01/02

Note – This is not the intended format. It will be more of a chart eventually.

R10 - mouser part #279-100K $1.08
R7 (390K) and R15 (680K) - no 0.1% parts available in this large a value (use 1%)
R26 - 1K 3000ppm (tony includes this in his rare IC kit)
R9 - i used a 10M in place of the 2M2 (see manual text) for finer control of FINE tuning however
i don't advocate it because my FINE pot seems to do nothing at all........ anyone ?

The best way to get a J112 in the US is from radioshack.com. even though you will pay more in
shipping than the part costs....(need batteries??)
Rev: J112 also avaialable from Mouser – part number 5122-J112

Directly from analog devices on their website for the following:
U3 - LT1013N (also available from Allied)
U1 - OP177GPN
