Philco 19H weak/no reception
#19

Hi everyone, great news! The radio is alive and well. I tried 2 different good tubes and went with the one that worked best. However, either of the two good tubes did not like lowering the oscillator resistor down to 10kohms, so I left the 15k in there. I actually put a pot in the circuit to find its "sweet spot" with both tubes and it liked the 15 k ohms best. I don't care, it works great now, now to add the MP3/ I pod jack so I can listen to old radio shows. I put in the 1/8" audio jack on the ungrounded end of the volume control. It works, but there is some bleedthrough from the am dial. I built an audio isolation transformer from the Radio Shack plans ( I forget where I saw that) but need an adapter to go from the rca jack to the 1/8" audio. Thanks to all for your help here. PS- I just bought another Philco 19 cathedral yesterday!! That one is now on my long list!!
