Need help identifying Magnavox S031 / Style S311-81 powered speaker cabinet & advice on restoring it

[Hannahbanana]

Hi everyone!

I'm new to vintage audio, so apologies in advance if any of my terminology is off!

I recently thrifted this speaker and from some googling I believe is a standalone Magnavox powered speaker cabinet. My hope is to get it restored and eventually use it with my record player, but I'm not really sure what I have or what's required to get there.

Here are the specs as far as I can tell:

• Model: S031
• Style: S311-81
• Cabinet tag lists 150 watts
• Tube-powered amplifier built into the cabinet
• 15" Magnavox woofer stamped:
  • 583845
  • 232 816
• Horn tweeter
• Chassis is stamped 91-1
• Front has a treble control, pilot light, "INPUT" jack, and a "REMOTE AMP" connector.
• It powers on and the red pilot light comes on, but I haven't left it powered for more than a minute or two since I don't know its condition.

From searching around, I'm wondering if this may have originally been a powered remote speaker from a Magnavox console, but I'm not sure. I'd love to preserve as much of the original equipment as possible while getting this cabinet working as a speaker for my record collection. Appreciate any guidance!

The amplifier looks to be an Amp-150 or variation of.

It's a Mono Bi-Amp
