[Boatanchors] Toroid Tank coils for HF Linear

[Revcom]

John,
The ARRL -RF Amplifier Classics- book has an article from October
'86 QST using stacked toroid tank coils.  May be of some help.
Used an 8877 tube, high power.  Motorola application sheets have
a lot of reference mat'l for solid state stuff too.
