    Accuphase P-300/X/L/V

    Are there any Accuphase owners who can share (if applicable) their experience with the P-300 line of power amps? Any big sonic differences between the original P-300, the P-300V and the ones in between?

    Accuphase P-266: replacing the NTC to limit the inrush current

    Hi everyone! I completely recapped the Accuphase P-266. Once the amplifier is on, it runs great! But charging 4x 22,000uF filter capacitors causes a high inrush current. Every time I first start it, the circuit breaker is trips because the inrush current is too high. This also happened before...

    Accuphase E-202 blown power supply

    I started working on an Accuphase e-202 for a friend, they weren't sure what was wrong with it as it had been sitting for almost a year since it stopped working. I was going to power it up on a dim bulb to see what was wrong with it, but opened up the amp first to see if anything was visibly...

    Accuphase E-202 Driver board factory changes?

    The only SM I have available shows the standard driver circuit for PCB 710-0002-00, however I'm seeing a fairly major modification that appears to be factory but I may be wrong. I've read the service supplements and aware that in April 1976 it was recommended to remove D6 and R35 and replace...

    Accuphase C-200 Distortion After Warm-up

    Greetings! I've had this Accuphase C-200 Preamp for several years now.

If I give the signal more gain (volume) the distortion seems to disappear. The signal...
