Not really, domestic low cost version. saves a bit of money.

True. I take it quite seriously. I was almost Blue Crossed 25 years ago
when someone tried to help me while working on a 500W (output!) VHF
commercial set. The turkey was thouching me when he reached into the
plate compartment. We both flew about 12-15ft and he left via ambulence
and if the combined shock and flight didn't hurt him I was going to. I
in some pain for days afterwards.

Cant! confounded editor on this MS box like to go from insert to
overstrike, very annoying.

that's the problem. though I do have a small carpet square to keep
from scratching the screen.

True in this case but many TVs are not. I have a color set I have
to look at (color skewed to red) that is very unsafe... isolation Xfmer

No arguement. We retired a leader LBO505 Oscope as unstable calibration
due to bad caps yet the Tek 316 is still going strong and in calibration!
