[Amps] Alpha 87A Power Supply Question

[Jim Brown]

One very good way to do it is what K4XU did in the Ten Tec Titan 425 
(circa 1978-9), whose power xfmr has two windings that are strapped in 
series for 240V and in parallel for 120V. When strapped for 240V, 120V 
is obtained from one of the primaries.

Last I looked, it is a code violation for the Green Wire to carry load 
current. Older appliances did that, but while ancient installs are 
grandfathered, it has been prohibited for new installations for decades.
