How to connect a yamaha p7000s amp to an adcom gfp-555 preamp


Use "Main Out Norm" from the gfp-555 pre-amp and connect to Canon connectors of the Yamaha. This requires a standard RCA to Canon cable for correct connection. Start with this first, if that works OK than try the "Lab" output of your pre-amp, but I am not sure if the Yamaha can handle this or the results of sound quality. Your choice.

Can i plug my phone into my p7000s yamaha amp I've bought. It has not been delivered yet. Also what is the option for speaker choice as I don't have a lot money spare. thanks.


This is a brilliant and hugely powerful amp. If you wanted you can take a 'y' cable out of your phone, mini jack into left and right 1/4inch jacks, to plug in directly. However, it would be better to invest in a small mixer, 5 channel maybe, around 40-60 pounds, with one mic channel and 2x stereo channels. This would allow you to keep the amp on full volume, for best results and control, while having a proper control unit with knobs or faders on a table top with the sound source. Far, far better than plugging in direct. Otherwise you would have to keep adjusting the controls on the amp, separate channels, which is a pain!
Take care over choosing speakers because if they are not powerful enough you will blow them up in your excitement! I'd go for a pair of 8ohm 400-600 watts rms. full range cabs - 12inch or 15inch driver with horns.

Put wrong power adapter into a Yamaha DTXPRESS IV


You should immediately quarantine what you plugged in and compare it to the correct one.

IF you put too low aq voltage of the CORRECT polarity nothing should have happened.

If you put backwards polarity of any voltage the regulator is probably fried internally and possibly an input bypass cap. Also if you put an AC adapter and it wants a DC the same destruction could happen.

if you put too high a voltage, possibly the power input cap may be bad.

It appears that the correct supply is the PA3C which is a 12 volt, 700ma with positive on the center pin.

The screen of my SPX-90 yamaha reverb is showing weird symbols and the unit does not operate anymore. Any idee od the problem? Thank-you


Check the power supply voltages. Likely the 5 volts is low or out of tolerance. You MAY need to check that it is pure DC as bad filter caps can cause it to ripple out of operating range BUT still show OK on a meter.

No power to filter capacitors. have power thru on/off switch to relay down to fuse, but no power to big caps / filter caps. i am suspect to a capacitor mkp61 (is this a switch?). i have voltage on the...


After switch through relay then down to fuse you should come to a full wave rectifier (solid state vs. tube?). The output of the rectifier goes to the filter caps. example: +30vdc, -30vdc with respect to ground. Best of luck.
