Hi Sascha,
The Chebycheff Times are long over ;) This was the parallel resonance era (vulgo Ghetto) and is no longer Valid.
The answer is simple:
Just use that Spreadsheet:

While 17m might still work with decent efficieny, I could not make this work higher up.
Yes, it would create Power, Yes it would work, but efficiency was around 60% at best for 10m Band....
And
to save you all some Time, I´ve already calculated all the Values for
3x BS170, 13,8V Input Voltage and 5W desired Output....
| 3x BS170 (theoretical) | | | | | | | | | |
| Band | 80m | 60m | 40m | 30m | 20m | 17m | 15m | 12m | 10m | 6m |

| Load (Ohm) | 12 | 12 | 12 | 12 | 12 | 12 | 12 | 12 | 12 | 12 |
| C1 (pF) | 657 | 420 | 307 | 199 | 128 | 88 | 69 | 50 | 39 | 0 (-1) |
| C2 (pF) | 1864 | 1240 | 941 | 657 | 472 | 367 | 315 | 266 | 237 | 132 |
| L2 (µH) | 2,04 | 1,36 | 1,03 | 0,72 | 0,52 | 0,4 | 0,35 | 0,29 | 0,26 | 0,15 |
