Repairing the HP141T based spectrum analyzer

The 8552 IF section of my 10Mc-18Gc spectrum analyzer (HP141T with the 8555A plug-in and 8552 IF) stopped working recently during the fabrication of the MIT IAP course radar. While trouble shooting the problem i took these photos to show the insides.

The 141T/8552/8555A remains my favorite spectrum analyzer. Now that it is working again i hope to get a few more decades of use out of it.
