Plain 120VAC for all of the [34]/[12][68]0 enclosures. (just getting <br>
caught up on this thread)<br>

The fans are 120V in that chassis, if memory serves. Are there RIFA <br>
capacitors in the input section of that power supply?<br></blockquote><div><br></div><div>Ah ok. Yeah that makes sense. The air flow requirements would justify stronger 120VAC fans. </div><div>I have not yet taken the PS apart yet, so I haven't had a visual inspection yet and whether it has RIFAs. Either way, I'm not going to fire it up without my current limiting dim-bulb tester, Variac and Isolation Xformer. Unfortunately the lettering on the PS is starting to disappear and cleaning the input side will most likely erase it all. I think I saw a section in the FE manual that has a rough description of it. The unit is at another location for storage so I'll have to take sections of it apart to move it by myself without breaking my back. Too many other projects going on at the moment. </div><div><br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">

<br>
3/60s take standard 30-pin parity SIMMs, there's nothing Sun-specific <br>
about them. I seem to recall it needing 60ns, but I know I've used 70ns <br>
in a pinch.<br></blockquote><div><br></div><div>Good to know, thanks! </div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex">
