    KR-5030 faceplate spacers - cursed aging broken plastic pieces

    I can't take my front panel off right now, but I pulled my selector knob off of my KR5030 and the nut for my selector switch shaft threads onto a metal (brass?) fitting. I don't ever remember seeing those plastic "Bosses" as the service manual calls them and I've had the front panel off several...

    KR 5030 tune up

    Mazeppa, The "m" is just the way Kenwood refers to all parts on the "Audio Unit" board in the parts list. For instance, all the caps are listed as Cm1,Cm2,etc - resistors Rm13, Rm14, etc. All the parts on the Tuner section have a "g" and all the parts on the Power Supply have a "k". The...

    KR 5030 tune up

    There's no adjustment for DC Offset on the KR5030. Only bias. To set bias, check pins 16 & 19 near VRm1 and pins 21 & 24 near VRm2. Should be 15.5 mv.

    Dustcover Hinges on Dual CS 508

    It's been awhile since I was inside my 508 -- I think the bottom cover comes off fairly easy. Once off, you can see what the problem is.

    Dustcover Hinges on Dual CS 508

    If I recall, there's adjustment screws for these hinges in the back of the base. Maybe the stuck one is too tight.

    Amplifier Distortion, DC-Offset, and You!

    Need suggestions for Onkyo TX-890: 37.7mv/102.1mv Offset is 37.7 mv in one channel and 102.1 mv in the other. There is no offset adjustment. Just bias. I'm going to replace the two differential pairs and see if that makes any difference. For Q501 and 502,the bases have -1.9v for the right...

    Tuner presets on Yamaha R-700

    I've been following the threads on the problems with the presets on the Yamaha R-x00 series. I've got a R-700 that has the symptoms (won't lock on a station except the real strong ones, presets don't stay in memory, tuner scans but won't lock, etc.). From what I gathered, this is caused by a...

    Kenwood KR-5010 power switch.

    On my KR5030, I took the little grey box apart, filed the contacts (they were burnt), reassembled and it has worked fine -- but then I've run it off of a power strip ever since.

    Yamaha cassette deck

    Yamaha K700 On the K720 (similar panel), that button was the "Mute/Search" button. It inserts a 4 second blank when recording. The K720 manual is available at http://www2.yamaha.co.jp/manual/pdf/av/english/cas/K-720.pdf Hope this helps.
