OK I'm late with this response due to time zones and work. 1/ Well done on fixing it. 2/ The "always enerigised was in fact "won't switch over". There are two contacts per coil assembly, one for set

Also, guidelines and practices for the Bell System were meant to maintain millions of contacts that were expected to undergo millions of operations without failure. Your 8566B attenuator might see a

I somehow doubt our system of coarseness is the same as yours, Chuck. 1500 grit paper is extremely mild. In fact it's used in car refinishing to buff up clear coat (varnish). So you can think of it as

There is a way to install linux-gpib on a Raspberry Pi, running one of the debian derivatives. That is documented in the project files describing how to make a LAN connected GPIB controler out of a

Re: HP 5245L: unknown chassis capacitor
Or use a DC fan instead - it will be much less noisy and there are plenty places to tap off the voltage.? The only issue is getting it mounted properly but it can certainly be done - I have a couple

Re: HP 5245L: unknown chassis capacitor
You might see if you can see any model number, operating voltage or frequency range on the fan itself. It might not be happy if you remove the capacitor depending upon the characteristics of the fan.
