WRL Model LA-1

[George Maier]

Alan:
It's a 7H, 200 mA choke, but the book does not say anything beyond that.
Based on the operating parameters of the amp, I'd guess the operating
voltage would be at least 1500 VDC; insulated to 5 or 6 kV. 

WRL used the exact same choke (WRL part # 1300-008) in the Globe Chief 90,
Globe Scout 680, DSB-100, Hi-Bander, Globe King 500B, and probably a raft of
other rigs as well.  Some manuals identify it as a 200 mA, some as 350 mA.
The 200 mA is probably and average current rating.  

Good luck....

Guys,
 
Anyone happen to know the value of henrys and operating voltage of the  
filter choke in the power supply of the LA-1.  I have a schematic and a
parts list 
but there seems to be no reference to values.  Mine is buzzing  like crazy 
and although the amplifier seems to be working well, would like to  replace
the 
apparently defective choke.  Thanks for any help.
