forget it - DEC H777 PSU

Forget the 230V bang issue, it IS a 115v PSU from an industrial site! Now we just have to find out what's gone pop... ---------- Forwarded message ---------- From: Adrian Graham <binarydinosaurs at gmail.com> Date: 24 February 2010 15:39 Subject: DEC H777 PSU To: "General Discussion: On-Topic and Off-Topic Posts" < cctalk at classiccmp.org> Folks, Got a PDP 11/04 on the bench here at work with an H777 (54-11599) PSU in with a sticker on it that says 'pop, bang & smoke'. I've downloaded the maintenance printset from Manx (yay Manx) but before I even begin I've noticed a terminal block on the transformer that indicates a jumper between terminals 1&2 and 3&4 for 115V and an additional jumper between 2&3 for 230V. This third jumper is missing so have the owners of this PDP just put 230V across a PSU jumpered for 115V?
