The VCO wave switch is an ON-ON type, but is a two pole (2P) switch. This essentially means that there are two switches internally controlled by one toggle. These are sometimes called DPDT or double pole-double throw.

The manufacturer’s part numbers for the chosen switches are:

SPDT

On-On

7101MD9AV2BE

SPDT

On-Off-On

7103MD9AV2BE

DPDT

On-On (2P)

7201MD9AV2BE

Note that C&K are now part of the mighty ITT-Cannon organisation.

The ‘filter control’ switch may be obtained from Farnell, part number: 917-813. The other two

SPDT switches are part number: 917-801. The ‘vco wave’ switch is part number: 917-825.

MultiComp switches are similar and can be obtained from Farnell. Their Farnell part numbers are:

SPDT

On-On

444-2430

2 off

SPDT

On-Off-On

444-2441

1 off

DPDT

On-On (2P)

444-2453

1 off

Heatsinks are probably required. BUT this does depend on the power supply, local temperature etc. If you cannot hold the two power devices for more than 5 seconds after it is has been powered up for at least 10 minutes, then you need heatsinks. I use the clip on type of heatsinks available from most suppliers. These require no nuts and bolts, or heatsink compound. They simply push on, and friction holds them in place. Try not to bend the legs of the power devices when you push the heatsinks into place. If you are using the 3031 to power the tbDAC, then you are recommended to use heatsinks.

The topic of power supplies will be covered in its own section later on in this document.

Sometimes people like to substitute parts in place of my own recommendations. Feel free to do this, but remember that there is normally a good reason why I have selected that particular part. If you do find that, say changing an op-amp with another one, makes an improvement, please do let me know either via the Oakley-Synths list or directly to me.
