    Yamaha R-9 - Strange bias and offset issue

    Hello all, I am getting some very strange voltages on my Yamaha R-9. After testing it both on headphones and speakers and verifying that it sounded ok, I measured the offset and bias. For the offset, the left channel was a solid 18 mv, but I was getting a strange fluctuating voltage on the right...

    Oops! I accidentally broke an unobtanium switch

    Hello all, I just made a dumb mistake. When I was redoing rca connections and other joints on my Yamaha AX- 900, I accidentally put the iron down on top of the board, searing a hole straight into the switch that changes between mm and mc cartridges. :( The switch no longer latches properly...

    YAMAHA CR-2040 - Voltage for Lamps?

    Been working on swapping my meter and dial lamps out to LEDs. All LEDs eventually burn out, guessing the voltage is too high for the resisters or LEDs. Anyone know what the units internal voltage is or the lamp voltage? Thanks!!

    AK Acquisitions as Eye Candy

    I have picked up some great gear from Ak members over the years. Every transaction has been a pleasure. Last night I allowed myself the time to just listen. We know. Play tunes lots, but not always for our undivided attention. I picked the turntable forum because that's the heart of my...

    MX-1 had a great fall.

    I recently picked up a MX-1 for "parts/repair". . The speaker switches were pushed in from the pictures and the description said it did not power up. I've always been an optimist. It showed up nicely packaged. I pulled the cover off. It looked very clean and there was no obvious damage. I...

    CT-800 Lamp Modifications

    Hi all, I recently picked up a CT-800 for a whopping $30 in what I'd call fantastic condition. The lamps are out, which didn't surprise me for a 40+ year old model, and I've ordered replacements to bring the tuner back to life at night. Upon receiving I tore the unit down and did a deep clean...

    Onkyo or Yamaha?

    Hi All, I’ve been rocking an Onkyo TX-SR313 (low-end from 2012) into EV FR12-2 loudspeakers for years. My girlfriend’s dad is offering his 1982 Yamaha A-760. The specs seem close enough that I don’t know if my discerning ears would hear the difference. I don’t have a lot of listening experience...

    YAMAHA NS-1000M terminals +

    Hi, I inherited a pair of these speakers, and i'm happy to read on these forums that they are worth the trouble i had getting them from Denmark to USA! - My dad got the speakers as a gift from the Danish Yamaha rep back in the late 70's, i believe, so they do have sentimental value to me! I...
