Here's a few suggestions and some additional info on the Drake L4-B.

#1 should be a step-start to reduce current inrush.

The power switch in the L-4B has been a failure item over the 
long haul.  By greatly reducing the turn on load the switch may 
last the life of the amp.  Replacement are no longer made and 
a real challenge to find. 

#2 if the caps in the power supply are the original ones I would strongly 
suggest replacing them ASAP.  

#3  Here are a few URL's on things to consider.  Great Pictures of the L-4B  Best site for L4-B 

I currently own a L-4B that I've had for over 20 years.  It's a keeper.

Good Luck with the amp Tom.
