I'm working on a Philco 46-1226.  I replaced all the tubes except the 7AF7 and 6J5GT.  They were on backorder and the current ones in the unit appear to be working, but I'm not sure they are at full power.  When I turn the radio on I can only receive one station (powerful one in Albuquerque) and I'm experiencing feedback and a humming sound.  Also two of the tubes (both are the 6K6GT) become very hot - is this normal?

Any suggestions on the why I'm only picking up one station and getting the humming sound?
