Pendulum resistors

[Knotty Pine]

Could I sub a 2.2M resistor for a 2.7M in R11 and R12?

Do you have any others that you can wire in series or parallel to get you closer?

A 2.2M and 560k resistor in series will give you 2.76M for instance.

Subbing 2.2M might be fine, but without a schematic, it's hard to be sure. Mr. PedlaPCB will know...

Here you go, one pendulum schematic

The values of the LFO are abused a bit to get a particular shape... It will work with 2.2M but it alters the shape slightly.

I went ahead and ordered some 2.7M’s as I might need some in the future; as well as having learned it is a component integral to the shape of the LFO, I didn’t want to mess with the formula. Thank you again for your response - I appreciate how helpful this forum is.

I used a 2.2M and a 511M in series.
