I think I need a new amplifier for the signal from my DVDR output to

When I look up distribution amplifier, they seem to be from the antenna
to the TV, and aren't those different frequencies.

The 110volt amp is still a little warm, but I suppose after 35 years of
use without interruption, it could have failed. It's mark is Archer,
which was Radio Shack, but I know the very same thing was sold under
other brands.

Am I better off with 110vac or with one that uses a 12v wall wart?

TIA

Hi Micky,

I'm going to guess given the age, that this is RF distribution at either
channel 3 or 4 (US), so yes you are looking at a antenna distribution amp.

Way back then too, the power supply would have been a transformer, and
supplying not much current would have helped it's longevity.

However, if all of your TVs are now digital, there are much better ways
of distributing content.

HDHomeRun for one.
