Maybe it's time for me to re-test some of the AC motorized impellers I couldn't get to run quietly enough. Did you mean something like this - or are there cheaper-yet variable transformers that'd work? |
Yep, that'll work. I've seen some at Fry's for as low as $50, you can also go on ebay and do a search for variable transformer and get 20-30 hits. Some pretty good prices there. You can also get ones that have taps so you can hook it up to 120V and it will put out 0-240V so you can play with 240v equipment, which I've found pretty handy in the past. Some on ebay for $30 that'll do that. They are pretty robust, usually the only time they go bad is when somebody shorts it out and fries a winding.
