The L-100 series used the AO-43 power amplifier.  
-  Hammond organs were overbuilt, expensive, and durable.
-  The power transformer was spec'ed at 315-0-315 (and as a somewhat educated guess,) probably at least 150mA.  
-  You can use that transformer to power 6v6's without sweating.  It would probably handle 6L6/5881 without much complaint.  
-  For higher B+, go with a GZ34 for 410v or a SS rectifier for 445v.

It'll make a good 18 watter.

thanks guy's , actually I'm restoring the Hammond , it use's a 5U4G Rectifier Tube so I assume it powers the entire organ.
