The best solution to this problem is Ron’s SUPER 89 modification where the 36 oscillator tube is replaced with a 6A7. Take a look here.  https://philcoradio.com/phorum/showthread.php?tid=14919    
I had a Philco 19 that the oscillator would drop out. I tried every trick that I knew and could never make it work. I did the SUPER mod and it now works perfectly
