Nice front panel anyway. One picture makes it look like those boards may be wired to it. Hopefully that wasn't messed up.

Arem't the 11/15 and 11/20 the same machine? The difference being what came with it when it was origianlly purchased? -tony

I'm hoping to snipe it as it is the same as my PDP-11 of the unibus variety. Good spare parts. I'm not hopeful, as the front panel mee-mees will probably grab it for way more than my current collection budge will allow. I think a full /15 /20 recently was listed or may still be as well, and that guy would be smart to buy this one for parts. thanks jim On 8/20/2012 7:43 AM, Al Kossow wrote:

Paul Heller wrote: Commonly the first thing to fail in monitors are the electrolytic capacitors. Replacing these first goes a long way to reviving monitors and preventing catastrophic failure (blown flybacks and HOTs - Horizontal Output Transistors). Be careful to get the correct type of capacitor for the application it is used in the monitor, some need to be low ESR (Equivalent Series Resistance) - usually in the horizontal circuits or filters off the flyback, and the main B+ capacitor must be high quality to avoid overheating from ripple. If the schematics define the capacitor or give you a manufacturers number so much the better - then you only need to do some research to find what exactly the parameters of that capacitor were before replacing it. It isn't just the capacitance and breakdown voltage that are important! An ESR meter can help with deciding which caps to replace...
