Replacing power supply caps are a must. I use Elna Silmic II to replace the old coupling caps for superior sound. SS amps equipped with the older op-amps will perform better with newer op-amps.

I do find tube gear easier to service due to more room under the chassis, no stacked circuit boards, lots of interconnect cables and at times less components overall.

I truly believe that it was built with NO intent towards repairing the unit.

I had one with a simple channel out problem. I knew where the problem was. But was actually unable to get to the board withou dis-assembly about 90% of the unit. Rendering it - unfixable.

  A lot of the Japanese equipment seems to be designed as a puzzle box. Yamahas can be difficult to get apart too. Contrast that to Hafler, which is built like military gear. It is very easy to work on.
