thanks again for the replies!

i have a question about a mod on the philco repair bench site.

its the "gimmick" mod where you wrap three turns of wire around the volume wiper wire and connect one end to the det-osc. tube.
this is probably a stupid question, but i just want to be double sure.

only one end of this wire is connected to anything right?
the schematic makes it look as though one end goes to the det-osc tube, and the other gets soldered to the volume control.
im pretty sure thats just a confusing drawing, but i want to be sure.

also, i seem to have a note here that says to change the 9K resistor (9) to a 13K. and now i cant find where i got that note from.
can someone confirm that this is indeed an upgrade for the model 80?

how much voltage does the hookup wire ill be using need to handle?

and lastly (for now LOL) the speaker in the one im working on seems to be pretty well intact, but boy does the paper look old! (it is i know LOL)
is there anything that can be done to strengthen it a bit? like something i could spray or brush on?

thanks again for all the help so far.
ill post pics when im finished.
