Welcome, oldvaxguy - from another grumpy old git !
(Who hasn't a clue what you're talking about
, but I'm sure one of our vastly knowledgable members will, and can help you .)
Does your moniker mean you have a romantic attraction for a certain make of household electical appliances ?
This is - to a certain, fairly elastic and broadminded extent - a family show, after all .....
Enjoy yerself
