Heat?

Generally speaking, an amp protects itself from heat, shorts and overloads by refusing to turn on or stay on.

Overloads can be from excessive periods of high output and shorts would be wiring issues or a speaker blowing up.

You should be able to feel if it's hot. WHY is it overheating? Make sure it has sufficient ventilation on all sides and that vent holes are not blocked by dust balls. Ensure the fan (if equipped) is running as designed (some only operate on demand). Clean dust and debris from it.

If the amp comes back on after cooling, you're lucky. They only have so many self-protection cycles in their lives so continuously resetting or cycling their power without addressing the cause can do more harm than good.

If it protects immediately on a cool power up you should disconnect the speaker connections and try it 'naked'. If it comes up then diagnose which lead(s) are shorted. If it does not come up the problem is internal and should be left to an experienced hands-on tech.

Dust in the unit - clean with Canned air like a computer.

or Delamination on the printed circuit board.Don't forget to clean all contacts on the backside of the unit!

If cleaning doesn't work - head to the local Crest "AUTHORIZED" Service Center.

The F2100 remote is not explicitly listed as compatible with the AerialBox T2100, I recommend using the remote that came with your AerialBox T2100 for optimal functionality. If you have any specific compatibility concerns, I suggest reaching out to Dish TV customer support for further assistance.

I have the same model with the 8 track player, original manual, and original receipt dated 1975.

Probably nowhere as this is an Amazon / eBay special so made in China. You should be able to go to Windows Settings, - Hardware and tell Winderz to find a compatible driver. https://www.google.com/search?q=VIBE+SOUND+USB+Turntable+Model+VS-2001-USBT+drivers ..
