Hi, If anyone needs a 40A 120v/250v line filter I have an extra one you can have for $10 + shipping. I bought it new used it a while and decided I only need one 40A filter for my 20A variac. It weighs about 5 lbs and has #10 lugs on both ends. It kinda looks like a small 9Kv 30mA neon. Please email me off the list if interested or want more info on it at choad69-at-geocities-dot-com Thanks, Shaun
