<And also 2 holer AL-1500's which was as simple as using the AL-82 tube 
<chassis and a filament transformer. W8JI pioneered that swap for his own use.

<Never had a report of any failures.


##  Very slick !   Is the oem PI net  retained ?   The resulting plate load Z  
a pair of 8877s  would only be one half of a single tube.   The 2 holer  would 
double the  tune and load C..and  one half the UH  on each band.

##  Was an out board  B+  supply used ?
