Hello,

I have a spectrum analyser HP model 8558B. The sweep card has been
severely damaged by AC. I found the following components damaged:

Q40 HP 1853-0020 PNP si 300 mw Ft=300 mw TO92
Q33 HP 1854-0404 NPN 360 mw TO18
Q37 HP 1855-0417 JFET Nch D mode TO18
Q16 HP 1855-0082 JFET P-ch D mode
Q8 HP 1853-0388 dual PNP 600 mw TO5
U1 HP 1820-0223 GP IC opamp TO5

Any idea to get a good replacement?

Thanks a lot!
