7L12 tektronix spectrum analyzer
« on: March 24, 2019, 10:20:18 pm »
Hello dear sir(s)
I own a 7L12 spectrum analyzer and now is nearly dead I can see no trace on screen exept the readout characters as you can see to attach pic. Can anyone has a repair advice?

evripides,

welcome to the forum!!

Can you post another couple of pictures?

It would be good to see the complete front of the 7L12 and the settings of the mainframe.

Regards,

Check ALL tantalum caps.   Also the YIG is known to be a problem in these units.
