Hello. I'm taking a break from home improvement and TV projects to dive into a classic Philco 90.
The basement workshop is undergoing renovations after a rat infestation and water damage was discovered. So I'm working in the backup workshop / guest bedroom.
I acquired this heavily modified 90 about 8 years ago. Apparently, the original owner was an engineering whiz and really sooped it up.
Many of the tubes were replaced with a more modern equivalent. The original 27 detector with an octal 6H6 for example. Even an eye tube was added!

Yikes! That must have been so much work to modify. The front end looks mostly intact but from the detector down, it's been rebuilt.

Rather than try to make sense of all that, I track down a nearly untouched chassis with single 47. It came with a full set of correct knobs, but no tubes.
I discovered three paper caps had been tacked in across some of the bakelite blocks. I believe everything else is original
