Hi Tim,
 
Replacing the blower on the L-4B is not brain surgery. It is easy to do  
yourself.  Be sure the caps in the PS are discharged by leaving the rig off  
for 15 minutes or so. Disconnect the power supply from the power  source. 
Disconnect all the connectors on the rear panel and take the cover  off. There 
is no danger of shock since the power supply is disconnected and  there are 
no caps in the RF deck which will hold a charge. You will see how  easy it 
is.  Rather replace the blower yourself than risk  shipping the deck. You may 
be able to fix the original blower once you have it  removed from the deck. 
  Should you decide to ship it, do remove the  tubes and chimneys and keep 
them at home. Never ship the deck with those items  in place. Doing so 
invites disaster.

I have a noisy blower in my L4B, not the motor itself but the fan I think  
touching the side of the amp case. I have a replacement blower if the 
original  cannot be fixed. I'd like to send the RF deck to someone along with the 
second  blower for repair, any recommendations as to who will      do this 
work  or is there anyone out there doing this  work?


Thanks  Tim
