Hello,

I have a Philco 48-200 radio which has been recapped a few years ago.  When I initially turn it on the radio plays like a champ, strong volume clear voices or music.  After several minutes the volume grows weaker and weaker, to the point where I almost have it at max volume after 10 to 15 minutes in order to have sufficient sound.  When it is in this state the sound quality becomes a little muddled.

Is this a tube problem ?  (i.e. one of the tubes growing weaker as it warms up ?) or is this something else.  I haven't checked the tubes yet, but was hoping to get some guidance from the Phorum members.

Thanks in advance.
