Title: Need to order pots for Toei CM-F20U Monitor
Post by: fatsgt on September 27, 2014, 12:31:03 am
I have a sick Ladybug with a Toei CM-F20U monitor, I'm only getting red.

I think the issue may be with the Blue and Green pots that are rusted out.  When I touch the screwdriver close to the bottom I can see some blue and green show up. I can't find the the manual for this monitor but I need to order some new pots for it. 

Any idea which ones I need to order? 

Here's an image of the bad pots and the monitor schematic from the lady bug manual.

The schematic lists the monitor as a CM-E20U but I hope it's close enough.  I'm not very good at reading schematics.  Any idea of the value on these pots from the picture?


Looks like 1K's

Do you think these would work?

you require vertical mount pots,10mm carbon will do the job

Do you know if those pots will work on a Nanao Ms8 chassis?

I don't, I'm pretty new to this myself.  What I did was find the values on the Monitor schematic.  Mine were 1K for the ones I need to change.  These appear to be pretty versatile, you can fit them to different footprints vertically or horizontal.
