 A classic case of asking the time and getting told how to build a
watch.  Tube amps are not instant on. They take in the neighborhood of
10 seconds to warm the plates enough that they start to make sound. Is
this normal for an old amp like this?  It's normal for any tube
maplifier.  Changing the tubes will not improve the warm up time.   fjm
