** <del>+6V rail is shorted somewhere to the 0V rail.  Even with all chips and switches removed.  Not really surprising since both are used a lot.</del> SHORT REMOVED!  Also it's possible that irreversible damage may have been caused to chips due to this.

** 68k feedback resistor is shorted with the output of the A/B variable amp.  This hasn't given a problem yet but will mean that to presenters on A and B channel they will hear a very quiet signal, maybe not even one perceivable over electircal noise.

** Due to confusion between the WIRE numbers and serial PIN numbers the switches are arranged wrongly (I think) and this should mean nothing except that the switches perform the function they should, but in a VERY counter-intuitive way.[[User:Malcolm.chambers|Malcolm.chambers]] 20:33, 9 January 2010 (UTC)

* <del>Polar Video - May be to do with it needing a reference input to fade between video inputs.  It has an inpute labelled REF if I recall.</del>  BUGGERED.  To Be Thrown.
* <del>Make shorter Xlr cables for studio use. -- Preferably a few 2m (1m probably a bit too short), before next term if possible but not essential (Mike)</del>  Buy some black ones with any money left over, in addition to the four bought for OB trolley.
* (for dimmer rack) To810mj or equivalent.  Also two 270 ohm high power resistors, and probably diodes.  Even after this repair, might just blow again, or cause more damage.  We can cope well with 11 lights, rather than twelve.  I doubt we'll cope so well if any repair attempt leaves us with 6 instead of 11, so probably not a good idea to touch it.--[[User:Malcolm.chambers|Malcolm.chambers]] 18:18, 1 January 2010 (UTC)
