[Milsurplus] Bringing up old klystrons

[Peter Gottlieb]

I found a very nice old TS-148 X-band spectrum analyzer and would like to power 
it up.  It would appear it hasn't been touched i a good 50 years.

The LO is a 2K25 klystron.  Do I need to observe any special precautions or 
procedures powering this tube up?




On a separate note, I picked up an interesting RF PC board assembly at NEARfest 
which has a little SMA amplifier brick which turns out to be a 12 dB gain LNA 
for 9-10 GHz.  It would be interesting to see if it worked as a front end preamp 
for the TS-148!  Talk about differences in technology!

I have a TS-147 coming in tomorrow to use as a source...
