[Drake] Drake L-75 Amplifier on 10 Meters

[D C _Mac_ Macdonald]

Was there ever a kit, either Drake of after-market, to add 10 (and 12) meter coverage to the L-75 amp? 

I recently acquired a never used but incomplete L-75 and would like to add the extended coverage before installing the transformer. 

Does anyone have the construction details for the parasitic supressor choke for the plate B+ lead?  I have acquired an L-4B suppressor choke and hope it will work okay but would like to have an original or duplicate.
