Question about Technics Audio & Video Receivers
This is an older receiver...one with tubes and knobs.
the right channel to the speaker keeps buzzing and blurting music in stops and starts, at a loader volume then the other. i checked the wires, the speaker is fine...what is it?
what do i check
and how do i clean the 'pots' on the volume knob?
this is a question for an older tech...i imagine.

It could be a bad balance control potentiometer or just broken/cold soldering joints due to the age. Bring it in a repair shop. Thanks. ebcelectronics

Testimonial: "If I didn't say it before, thank you. You were right on the mark with the soldering joints. I took it to an electronics shop and they fixed the problem well. It wasn't cheap to say the least."
This type of calibartion is known as a logarithmic scale.
The numbers refer to decibels below the maximum output of the amplifier section of the reciever, or decibels of attenuation (making smaller/quieter).
Without going through logarithim theorey, the logarithim (base 10) of 1 is 0. So if 1 is the maximum output of the amp, as you turn the knob down from maximum you are adding more and more attentuation to the output (relative to maximum) and so the loudness of what you hear goes down, even though the number on the scale is going up !
Most peolpe associate decibels with sound levels, but anything can be measured in decibels, so long as there is soemthing to reference it against.

Problem is it is a common problem. I have one with the same thing, it appears as though HK discoed the line for a reason and sold them all at half price in Costco.

SOURCE: Hi I have Denon 1910
I SUSPECT THE CHANNEL IS BLOWN.YOU COULD TRY OPENING THE UNIT AND SEE IF THERE IS ANY GLASS FUSES.ONE MIGHT BE BLOWN.IF NO FUSES THEN TAKE IT TO A TECHNITION FOR REPAIR.THAT WILL BE YOUR ONLY OTHER OPTION.I KNOW,I HAVE HAD THIS HAPPEN TO ME.GOOD LUCK
