Philco 47-1230 low audio
#5

YEE HAW!!
OK, now there's audio! Many thanks for all of the help. I figured it'd be just as easy to replace all the coupling caps in 1st and 2nd audio stages, rather than testing them all first - plus, it might avoid headaches later on. I used ceramic type rated 3 kv - I hope they're OK for this application. I found correct values for the .003 mf, but was unable to find .006 mf - I don't think that's a standard value now - used .005 instead. I hope that's OK. At any rate, next step is an alignment, but I can see light at the end of the tunnel (it's not a train). Thanks a million!

Until next time,
Stirling KC0NXM.
