When you say the +5 is down .12 - .26 do you mean that the voltage is between 4.88 and 4.74VDC? If so, then you need to check the either the +5VDC adjustment (if present) or the primary and secondary filter caps on the +5VDC supply. If the voltage is 0.12 - 0.26 under load, but is +5 (more or less) without a load, then you have a problem in the regulation, perhaps the pass transistor, some bad connections, filter caps....<br>

&nbsp; Right now, my +12 is fine, dead on.&nbsp; The +5s are all way low; from<br>
.12-.26 Vdc.&nbsp; This seems like too much of a difference to have to<br>
adjust for.&nbsp; I wanted to check with you guys before I cranked it<br>
