If you're looking for the official Model 66 service bulletin (#197) we have that in the Philco Library:

Go here and type `66` into the search box.
https://philcoradio.com/library/index.ph...bulletins/

Or here's a direct link:
https://philcoradio.com/library/download...%20197.pdf

Thanks to Terry (radioroslyn) we've made a few fixes to these long-standing bugs in the service info.

In the case of the Model 66 we haven't gotten to fix the missing tie point yet - but I will update our service bulletin this weekend.
