That circuit has a coupe of old incandescent filament panel bulbs in circuit. That was put together by a lunatic for reasons I can't begin to fathom. That is a total waste of space and likely to destroy any electronics you connect it to. It is total garbage, do not use it.

This is what the circuit is supposed to look like.

I did find a reference that Bose may have added a tweeter protection lamp at some stage. However the circuit you have is crazy. Trying to protect a tweeter with a lamp would just be another in a long line of Bose's crazy ideas. They have probably produced more junk then anybody. If it says Bose on the label run the other way.

I highly doubt you can order one. You will have to build it. You had better check that all the speaker drive units work before you spend any money. There is a high probability they do not. Be careful what you spend, as those speaker were junk when new and they will still be junk when you have restored them.
