Hi all,</div>
<div style="margin-top: 1em; margin-bottom: 1em; font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
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>
<div style="margin-top: 1em; margin-bottom: 1em; font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
I got it working by using two pairs of 1N4001's:</div>
<ul>
<li style="font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
One pair configured in common cathode</li><li style="font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
One pair configured in common anode</li></ul>
<div style="margin-top: 1em; margin-bottom: 1em; font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
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>
<div style="margin-top: 1em; margin-bottom: 1em; font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
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>
<div class="elementToProof" style="margin-top: 1em; margin-bottom: 1em; font-family: Calibri, Helvetica, sans-serif; font-size: 12pt; color: rgb(0, 0, 0);">
Any tips or recommendations for specific diode models would be most welcome.</div>

Thanks, </div>
