Optimum Tuned Circuits

Tube and Condition			Band:	160M	80M	40M

2E26, 6BQ6, 350V 50MA, Class C			24.5uh	12uh	6.5uh

6146, 807,  600V 100MA, Class C			21uh	10.2uh	5.56uh

6AG7, 12BY7, 300V 30MA, Class A			53.7uh	26.2uh	14.3uh

All the above assume Q=12 and use of tune or trim cap of at least 250pf (160M will need max
of 320pf) but 365pf would be plenty (no need for more.)
