Question about Adcom GTP-760 Amplifier
Anyway to use the Adcom Gtp- 760 if there is no remote? Unit is always in stand by mode.
If pushing the power button does nothing, the unit is probably in "protect mode". This means there is an internal problem and will require professional service.

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 or marginally low impedance loading by the speakers; 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 and competent hands-on tech.
Check for loose speaker connections as a root cause for intermittent shutdown.
