    difference between Yamaha AX-500 and AX-530

    Hello, could anybody tell me what is the main difference between Yamaha AX-500 and AX-530? They both looks the same, the weight is almost the same and technical data look the same too.... There is even AX-630, which is almost the same, but there is added Yamaha YST slot. Thanx in advance. Michal

    Anybody have recommendations for a good powder coating restorer?

    Hi group, I have a nice Yamaha C-70 preamp, in good condition, that has a cover with some scratches. I've wanted to get the top redone in a nice black powder coat.

    Popping sounds after replacing an op-amp in a YAMAHA AX-870

    I guess I need some help with this. I have a YAMAHA AX-870 on the bench whose right channel was significantly quieter than the left. I have traced the fault back to a defective right-channel op-amp on the volume control board (NJM2068SD). As the component is rare, a Chinese import was the only...

    Yamaha B-3, no longer Sansui exclusive.

    After reading several threads about the Yamaha V-fet amplifiers I decided to get some myself. Always an exclusively Sansui man, I can still appreciate the efforts of other manufacturers in the late '70s. So this week two Yamaha B-3s arrived from Japan. And they did not disappoint! Great build...

    Hello folks, my yamaha cr-820 had shorted output transistors on the left channel, due to a broken piece of plastic allowing a short to the heatsink. I fixed that by replacing both of the left channel transistors and now the 68ohm fusible resistor doesnt burn up on me anymore. But neither does...
