Thanks Phoenix :)

Not a 7100 but have two KA-5700's and the treble and bass pots definitely influence the sound.

To be picky, it is a "Tone Defeat" switch and it should NOT be engaged if you want the tone controls to work...

Engaging Tone Defeat will bypass the tone control function and renders them 'flat' so nothing happens when you turn the knobs.

The purpose is so that you can hear the difference that the tone control settings make on a playback by switching back and forth between 'flat' and 'equalized'.

Yamaha was one of the first to come up with the marketing proposition (Pure Direct) that bypassing the tone controls was also more audiophile :D

Snip..
Can anyone tell if there is a resistor in the headphone path? It's 30 watts per channel so I'm guessing there would have to be. Though maybe low resistance. There is a little warning on the back that says 'only use headphones of high Z' I'm assuming this must be high impedance?   

A quick look at the schematic shows 0.22 ohm 2W resistors on the headphone out

Ah! Thank you my friend.

Matt I remember us discussing that mac a few months ago. So after all this time, he still refuses to budge? That's very surprising that he would rather let it sit up collecting dust instead of negotiating on the price.

^^ very true. Sometimes these wonderful pieces are trophies that end up being dust collectors instead of bringing real enjoyment from use.

:thumb: Me? I'd pick up some fixin's at the 'Big Chicken' to go and set it down on his counter :evil:with a bottle of Bourbon... "Pardon me sir, busy?"

It's not been a good morning here. :blink:

 

One channel on my Pionner Quad QX9900 is now working intermittently.

 

Does this imply simply a loose connection or something more serious? Anyone care to chime in?

Buy some DeOxit, spray it into every control that the signal goes through (including loudness, mono, tone defeat, and tape monitor switches). That might fix it, if it doesn't, you might have a more serious problem.

Cool, will try this asap and pray and cross fingers & toes.

Don't be shy using it as well. Give them all a good squirt and work the controls and switches while you do it. Leave it for a while before you plug back in so that the excess evaporates.

^^ Also be sure to take the time an effort to disassemble things necessary to actually get to the pots and switches. Spraying in the general direction of them or trying to spray from the front panel will not do the job.

Thanks guys. DeOxit may not be as easy to find here in Singapore as I thought. Venturing out and about Monday morning for this.

post #10980 of 16886

DeOxit has become harder to find locally. I used to pick it up from Radio Shack but now I just order from Amazon.
