All W&G gear comes with teardown tools! Look behind of the previous one, there should be a gray box that contains spare fuse, hex key and usually hook for lifting boards. You also should be able to lift whole internal cage out after the top cover is removed. These are absolutely fantastic gear, sadly most of them were made for analog and early digital POTS network measurements, so many of them are obsolete at least in their original use case. I have disassembled couple of W&G T-carrier analyzers, both had failed due leaky NiCad batteries. I still have the cases around as I was planing to make kick-ass computer case out of them.

Couldn't you use that frequency oscillator to test audio equipment like a tube amplifier since it goes down to 20 hertz ?

Just an FYI: I have two PCM-4's of which one is in auction. But if a member in good standing in the EU (prefereably close enough to Belgium) (yes, the UK still counts for the moment) is in interested in a good teardown I'm willing to send one free of charge. For the fun of it. I'd send it to Dave but it would cost me a arm, a leg and possibly one of my daughters to ship and then it would probably only arrive in bits and pieces anyways. So, if anyone's interested..
