    Speaker Recommendation

    Thanks for the suggestions. I forgot to mention I have three cats, so the Vandersteen would not work. I will look more into the Tekton - Lore may work , however I am a little reluctant to buy from a internet only dealer. I have a set of high efficiency stand mounts from a internet dealer that...

    Yamaha CA -800 Circuit Board

    I ended up doing just that and have got it working. And a distinguished AK member has a replacement board for me as well.

    Yamaha CA -800 Circuit Board

    The bottom right corner was completely snapped off. I have glued it back together, and resoldered the broken circuits. I tried it out, and it did fix the “no sound at all “ problem, but unfortunately I did mess something up , as now it blasts distortion when I turn the amp on, even with the...

    Yamaha CA -800 Circuit Board

    According to the service manual it is # NA 06503 but it looks more like 06680 written on the board....though it is not very clear.

    Yamaha CA -800 Circuit Board

    I am trying to fix a CA - 800. It has a broken rear panel circuit board which I am attempting to repair, but this may be beyond my limited skill set. Other than e-bay, which I am monitoring, is there anywhere where else I can look for a used one to replace it? Thanks

    CR-420 right channel issues

    I have the same issue on my 420.....channels cut in and out when tapping on the relay. However, on mine , it does the same thing when using headphones. Does this rule out the relay as the problem?

    CR-420 with left channel distortion

    Don’t think so, meter seems to work fine for dc offset measurement on the Yamaha .....checked the idling current on another amp I have open beside it and I get a reading on that.

    CR-420 with left channel distortion

    I am still fiddling with this amp....cleaned contacts etc again and I checked the dc offset and it seemed fine, but when l went to measure idling current, and get readings of 0 on both left and right. How can this be or what am I doing wrong? Red to tp1 - black to tp2 - receiver on for 10 mins...

    CR-420 with left channel distortion

    The one in my cr 420 has writing on the cover, so I was curious if the one pictured may have been a replacement. At any rate, I sprayed all the switches/controls that I could access and if anything I made it worse.....the distortion is now more pronounced with the tuner ( which was the one...

    CR-420 with left channel distortion

    Will do. I am a rookie at this - is there a way to clean the push button switches without taking the switches apart? Spray deoxit in from the front?

    CR-420 with left channel distortion

    I have similar issue with a cr 820 I just got. Distortion in right speaker. Very noticeable using aux and tape inputs, a little less with phono and hardly noticeable using tuner. Distortion goes away using headphones if both a and b speakers are turned off. The unit is very clean inside and I...
