Yes, this is the style of foot controller. I love mine because it DOESN'T get warm! No matter how long I use it, my foot doesn't get fried. And, I agree with Joe, the right position is immediate. So handy!

I wonder if the resistance in the components is greater when they are aged through use? My Ambassador looks practically new. It was kept in its box, sealed, for decades. The cord is not twisted and is still like-new flexible. Grant? Joe?

I am not sure what you are asking. But in my experience, the carbon type usually get hot if it has been used a lot at slower speeds.

You answered my question. Thank you!

[ATTACH=CONFIG]482285[/ATTACH]Here is my recent addition and having spent hours trying to find out more about her I have come to learn she is basically a Singer 15 clone.....I love her nontheless - she was owned by an elderly lady who never used her and so is in pristine condition bar a few age/storage scratches on the base box.

What a fun thread Miriam - there are so many great variations!

That Pfaff is beautiful!! In fact, my husband was curious where I can find one like it. Too funny.

Amazing machines

They are not that easily found it seems...and only saw pictures of a couple in Europe and another couple here in UK :)

That Pfaff has to be the prettiest clone I have ever seen. WOW Lucky you. I think someone has to die before you can get one like that. Nice case, too.
