Tektronix 2215(Non-A) w/ Opt48 - Need list of all maintenance replacement parts

[t1d]

I am preparing to open my scope and change out all of the known problem components... Electrolytic caps, carbon comp resistors, Rifa caps, paper caps, etc. I am concerned that I might miss something, either on the board, or in making my parts order. So, I am hopeful that you can point me to a known, good, comprehensive list of the parts that should be changed out, as a matter of course in maintenance.

I have searched the web, but I only find incomplete lists, or lists that include "ghost"parts... a term I am using for parts incorrectly labled in the manufacturer parts list, such as tantalum caps listed as electrolytics...

I really love my 2215. Even though I have a digital scope, an analog scope is the right tool for particular jobs... such as looking at curve traces. I would hate to lose it over a simple component failing and cooking it, or leaking and eating up the board, etc.

After swapping out the parts, I will need a good thread on calibrating it... But, only one bite of the elephant at a time.

Thank you for your help.

I don't know of any such lists.   Your best bet is to tear the unit apart and inventory the board looking for obvious issues to address quick.   You might try searching Google for a BOM (bill Of Materials), it is surprising what can show up with a Google search if you get your Google fu working right.

I can't say I'm a big fan of replace everything for maintenance, however capacitors are a real issue so starting there makes sense.   Also looking for repair logs or threads should give you insight into other failure points beyond capacitors.
