Custom Hammond Power Transformer
#42

Very nice work on that transformer! Now you can move on to the next steps. +1 on not using the dimmer control. They do introduce tremendous noise. Dim bulb is simple, cheap and works well. You can change the load limits by simply changing the bulb (incandescent). I used a socket with a couple clips for some time, but later got a couple metal boxes from the construction store, a box for a ceramic (or plastic) light socket, about $2, a double box for an outlet and switch to bypass, a cord, something to connect the two boxes. I'm sure I have less than 10 in all of it, and you might have most of it in your garage! Variacs are readily available on the auction site, and would be a good idea to have. Also, you might want to take a look in the future for an isolation transformer. Hamfests are a good source, as is the auction site, but they are kinda heavy, so shipping may be a little more. You really dont need that until you start working on things without a power transformer.

All it is- power cord hot to the bulb, then hot from the other side of the bulb to the outlet hot (gold, small slot). then neutral to the neutral (silver, long) side of your outlet. Then, wire your switch across your bulb. This can bypass your bulb if you want to jab it. Just remember, this is only a current limiter/fuse, not isolation.

Edit: I have a couple Heyboer transformers (used) patterned after the Dynaco ST70 and they seem like very good quality transformers, so I recommend them highly.
