Screen Grid RF coils were used in TRF receivers using Tetrode valves in the early 1930’s. They solved the stability problem of using neutralization in triode receivers. Later superheterodyne receivers superseded both.
Available in 3 kit types:
- 1930/3, Kit of 2 units - Aus£0/15/0.
- 1930/4, Kit of 3 units - Aus£1/2/6.
