I am doing my annual shack cleaning, and I have a used National MB-150 Multi-Band Tank Assembly. I believe it can be used in push-pull and single-ended output tank circuit designs, with an RF output of 150 watts or less. It can also be used in the grid input stage when the drive/input power is 150 watts or less.
Unfortunately, I have no other technical information available pertaining to this unit.
It is quite dirty from age, but it should clean up nicely with a little elbow grease.
The price is $50.00, plus the cost of shipping to your QTH.
