A few notes.
Sams never listed Canadian sets but usually there were US versions
that were near identical.
The CTC39 was almost the same as the CTC38 but I dont remember
the major difference. I dont remember any CTC38 with instant on.
I do not know the feature your set has. It sure sounds like "instant on".
Most sets with instant on will have gang on/off switch. Some would
have two or 3+ switches on the one on/off SW. Normally the set WILL draw
current when off UNLESS there is a standby/vacation SW involved.
Look at the on/off & see if it has multy switches instead of the usual
SPST switch.
BTW there is someone offering Can manuals on the list. do a search.
