Philco 90 1-47 Triode
#24

First off, a great big thanks to all those who have pitched in and helped. Im not a stranger to electronics really. I started off many years ago working for Motorola and GE on the commercial communications side. Repairs, installs duplexing and multi-coupling were specialties of mine. Any ways, mostly transistorized stuff along with a few commercial broadcast FM stations Running stuff like 3CX15000A7s. 

Until now i have mostly been restoring communications tube gear from the 1950s and up. So this Lowboy model 90 is my first step into the realm of the 1920-30s' Hence i have lots of questions. I like doing restores right the first time. 

And yet another question.

C24 is comprised of a .1  .13  &  .25 - How do you know which is which on the schematic? Its currently under a steel cover, will is become apparent once the cover is off which is what value?

When you say ohm the coils are we just looking for continuity or are we shooting for a specific ohmic value?

I havent started work on this thing yet. I have orders caps and resistors. So while I wait for those to arrived I will read and research to be best prepared to make a decent job of it.

Cheers
