AM and Shortwave antennas

[trudie]

I have a Veric, it looks like an isolation transformer is different. Does it some how prevent electrocution when touching the chasse?

After reading a WIKI on isolation transformers it sounds like something I should integrate into the VARIC box I am building?

Yes use them together. There are some nice combos but since
they are so useful they are expensive. Example:

If you have spare meters put one in for AC amps 0-5 &
one for output AC volts 0-150 Also fuse the output at 5A

You can do that or keep them as separate boxes that can be plugged into one another (easier to lug only one when both are not needed).

By the way it is spelled Variac and resistor not varic and resister. Technically a Variac is a trade name for a speciffic company's variable auto-transformer, but it has become like Kleenex or Bandaid...Synonymous with the product regardless of the maker.

Never noticed where but I would put the Variac after isolation.
With it you will be safe, can turn it down to break in a set &
sniff out weak tubes that wont run on reduced voltage.
Monitoring the current is essential for troubleshooting TV
Hoz & HV circuits in solid state ( SS ) sets.
Going higher is a good test of a SS sets regulator.
You can test things that run on 24 VAC or other low AC
voltages, just dont bump the knob !
