Woohoo! Thanks for the info.

So now aspiring silver colloid cookers can run wild without their current running wild. Thanks. Your prompt response is most appreciated. Sadly, SOTA Instruments has stopped marketing their constant current adaptor and I hope this resource fills that void.

Hi Nord,
You need to order the J505 (1mA) TO-92 Thru hole version. Looking at the bottom of the device, the left hand terminal (1 or A) connects to the positive side of your battery stack and the right hand lead (2 or K) connects to the silver rod. The negative lead from the battery stack goes to the other silver rod.
