After I started rebuilding my K40 some time ago I cannot find the stock

After I started rebuilding my K40 some time ago I cannot find the stock green ballast resistor anymore, I am 50% sure it was there :frowning:

Does anyone use similar part like this one here? -> https://www.aliexpress.com/item/AE-50K-Ohm-200W-Watt-Power-Metal-Shell-Case-Wirewound-Resistor/1121557665.html

And where was the ballast resistor connected, between L- on power supply and via Ampermeter to GND?

my k40 came without any balast resistor -brought mar 2015

Mine either

These are found on the Moshi powered systems with older power supplies.

My K40 was originally Moshi based, but I scrapped all stock boards. It is possible that the resistor has been connected to Moshi and after getting rid of it is not needed anymore. I need to search for old pictures.

I’m using a 60Kohm 100w resistor in green that looks similar to your picture. I soldered the wires on, then put heat shrink over the top right up to the housing. here’s a 50Kohm listing http://www.ebay.com/itm/100W-50K-Ohm-Screw-Tap-Mounted-Aluminum-Housed-Wirewound-Resistors-2-Pcs-/310578131352?hash=item484fe63198

@sszafran It would depend on which power supply you have, not the control board.
