Chuck If you failed to get the Racal - don't worry, the HP is a better product without all that aggravation that comes with doubts about the front panel buttons that frequently fail, and the symbols that wear off. The HP 5334A or B are a better bet, and the 5445A even better, if you can accept the additional size and fan noise. I intend replacing the fan in my 5335A with a 12 volt substitute. Its just the hassle of finding a 12 volt 300mA ? source within the instrument.
There is a +15V supply, but if you tap off prior to the 7815 and hook in a 7812 if you don't feel like using just a serial resistor.
Haven't bothered to replace the fan yet. Cheers, Magnus _______________________________________________ time-nuts mailing list -- [email protected] To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
