Krohn Hite 2000 (1983)
I won this of eBay for just over £13+P&P, it was sold as Used (but untested), the light on the front did come on, but no output from any of the BNC's.

After some testing, i found a short on the -25 volt rail of the power supply, i ended up cutting the wire links from the main board to the power supply, to track down the sort, it ended up being two of the tantalum capacitors that had shorted, i replaced all the tantalum capacitors with new ones of the same values, i only had to replace one resistor that i burnt out when testing for shorts.

After a bit of a cleaning, it's now fully working again.
