Philco 40-180 Chassis Restore
#38

Pleased to report that the old 40-180 has come back to life. Performed first power up after the recap/rewire yesterday with good results. Brought voltage up slowly on the variac, started making noise around 90 volts, and at 120 volts AC was getting 274 volts DC across the first electrolytic cap, and close to 180 across the second. Also picked up several stations on Broadcast band, so I’m pleased so far, especially with this being my first chassis. 

Was getting an occasional popping noise from speaker. Believe it was the 7B7 tube as it got worse when I wiggled it and was also able to make it do it when I wiggled the band switch. Cleaned pins of the 7B7 which helped a lot and cleaned contacts of band switch more with Deoxit on a Q-Tip.  Going to let that dry well before powering up again, but believe that should take care of it.

Thanks again all for the help and advice, so much appreciated!

Now, on to refinishing the cabinet and eventually the alignment as I get things put back together.
