Yes, it's the very one. Let the buyer beware.. I should have read
the fine print and noticed that 220. I'm not too upset though, as
it's a cheap mistake at $10 and it is still useful to me. I have
spent far more on things that ended up totally useless. Heh.
Now I just need to get a handle on transformers. I have a 555 based
square wave supply I built, but can't seem to get any MOT's or
transistors to switch current. Square wave looks fine on my scope
off pin 3 of the 555, but no matter what I try I can't get a good
signal out of the transistor to boost the power. It stays high
with only about a 1 volt drop during the low part of the wave.
Anyone know and scrap metal places in the Boston area where
I could find transformers and other used stuff cheap?
