Hi, Everyone.

I recently aqquired used brick amplifier with only
CUBBEAR 175 in front of the unit. I am sure it is a category of VHF/UHF amp with maybe 175 watts.
Does anyone know who the really manufacture of this amp and what vhf or uhf band this is for?
(i.e 2m, 6m, or 70cm) I would really be appreciated for the information.
73, Adam

I've been wrong a lot of times in my life, and maybe I am now. But if memory serves correctly, this is a CB amp and not suitable for amateur use.

A Google search shows the site  below has schematics for something called a "Cub Bear 200 " amplifier .I'd wager it's something similar , and thus , likely for CB .

The Cub Bear 175 is a wide-band RF amp designed to
operate at its best efficiency between 25 mhz and 30
mhz . Output at maximum is 150 watts. It will work on
all HF bands and 6 meters but it is kinda trashy on
the harmonics. A low-pass filter helps but it will
still trash up HF. I believe that if a fellow were
to build a proper filter input/output network and
make proper pi-networks for this amp it would be a
great little amp to enhance a low power rig.
