<p>I'd go with standard 3 amp diodes. e.g. 1N540x, et al<br>

I have a Yamaha CS-30 in for repair that was dead on arrival. It
only needed the dual diodes (D1 & D2) on the PSU replaced to
get it working again.</div>

I got it working by using two pairs of 1N4001's:</div>

Both secondary fuses were replaced with 1.6A fast blow fuses as
per the service manual instructions. Given this, I figured any 2
or 3 amp diodes should work fine.</div>

Being such a nice synth, I'd prefer to have the best long-term
solution. Should I replace them with Schottky diodes for their
lower forward voltage drop and efficiency, or stick with regular
silicon diodes and opt for a higher current rating?</div>

Any tips or recommendations for specific diode models would be
most welcome.</div>
