I have a Poppery I with separated fan and heat circuits and the fan air inlets opened up for better air flow. Line voltage is 116 with no load and averages 116 (but jumps all over the place from 106 to 130) with fan on. When I turn on the heat the line voltage drops to a pretty stable 106, but the fan speed is way off.

I'm thinking of putting a variac on the fan side to get to at least 120 (this Poppery is a fast roaster; too fast). How big of a variac would I need for this? For the heat side, I'm thinking of a router speed controller if needed, but a bigger one than the Harbor Freight one that I already melted :-)

Thanks!

Hi CoffeeFishBeer,

Welcome to the forum.

A 500  VA Variac should be overkill for the fan in your P 1.  If you want to save some money the Mike McCoffee "Frankenformer" will also do the job. Here is a link to a picture and a schematic: Click Here (mdmint.home.comcast.net)

I hope I have better luck with my Harbor Freight router control.  I am replacing the wimpy roast heater in my Z&D with a 1500 Watt heater and I'm planing to control it with the Harbor Freight box.
