Question about Adcom GTP-830 7.1 Channels Receiver

Open Question

Hello, I have the Adcom GTP-830, it's an American one, imported. I live in the Netherlands, and I have always used it with an AC adapter 110-220 volts. Someone told me that the power print was prepared for use in Europe, this is correct. I changed the print as the print has the information to do so, but I can't find one single part that's written on the print to make it work. Do you have a schema for me, so I can find this part and control everything before I connect it? regards Peter

Hello, My ADCOM GTP-870 HD has recently started cutting signal randomly. I'll watching a movie and all of a sudden I hear a click, and no sound or picture and the front panel had no lights . The power...


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.

My Adcom GTP 760 Preamp/Processor produces a hum that is affected by the volume control. I think it must be a bad capacitor in the power supply but would like your opinion. I do not have a tech manual...


This is not likely a power supply problem, but is isolated before the pre-amp stage. This can be a defective IC in the preamp stage as well.

Adcom schematics are not generally available, but you may be able to isolate the problem with a little experimentation. Try to run a signal through to see if you can get the signal as well.

Please update this with your results.

Thanks,
Dan

Recently, after about an hour of play, when my Adcom GTP-760 is warm, a low level hum begins and can be heard on all channels regardles of the source selected. The hum cannot be heard when the unit is...


The filter capacitors are probably going bad is the likely cause.

It may also be bypass capacitor in the preamp section.

Noting whether the hum volume varies with the setting of the volume control would aid troubleshooters.

One might be able to isolate the bad component with freeze mist/circuit cooler.

No output in Right channel on my Adcom preamp GTP-450


Hi...
Have you tried swapping speakers to see if the trouble moves to the other speaker?
It could be a dirty selector switch .

It could be a broken solder contact on the input or output RCA jacks

No remote found


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.
