Chorus LFO questions

[Electron Tornado]

I was looking at the schematics for the analog versions of the Boss CH-1 and CE-5 choruses and noticed a difference in the LFO circuit.

Here is the schematic for the CH-1 (scroll down a bit):  http://www.diystompboxes.com/smfforum/index.php?topic=83103.0

The schematic for the CE-5 can be downloaded from here: http://www.eserviceinfo.com/index.php?what=search2&searchstring=CE5


The difference is with a resistor, labelled R55 (10k) in the CE-5, and what looks like R46 (15k) in the CH-1. Why are they connected differently?

R46 in CH-1 looks dubious to me.

R55 in CH-5 limits the minimum-R end of RATE pot.

On CH-1 drawing the RATE pot can be turned to zero which is sure to stall-out. While R46 prevents gross smoke from IC4a, BOSS typically does not give us knobs that go wacko at the extreme.

I think R46 is a drawing error. Wire like CH-5. 10K or 15K end-stop is a minor difference on a 0K-250K pot.

Thanks, Paul. I was able to check the boards of each of those last night, and you are correct, there is a mistake on the CH-1 schematic.
