Rheostat needed

Hi!
I need to find a rheostat for my sons boyscout project... he needs
a rheostat that will handle 2w ohms at 200 watts. If anyone knows
anyone who has one and would like to donate it or sell it at a
reasonable price please contact me.

Hi, Bill. I'm not sure a power rheostat is the right way to approach
your project, but there are a number of surplus parts that can do the
job.

For instance, Surplus Sales of Nebraska has a 35 ohm, 300watt rheostat
for $35 USD (their P/N (RWA) M22/11-0111). Not great, but it sure
beats $150.

Good luck
