| 5 units are finished now, after tuning the results are: |
| Amp | Pin | Ud | Id | Po | Eff | Bias |
| 1 | 3,2 W | 50 V | 7,5 A | 285 W | 76 % | 200 mA |
| 2 | 3,2 W | 50 V | 7,6 A | 290 W | 76 % | 200 mA |
| 3 | 3,2 W | 50 V | 7,6 A | 295 W | 77 % | 200 mA |
| 4 | 3,2 W | 50 V | 7,7 A | 300 W | 78 % | 200 mA |
| 5 | 3,2 W | 50 V | 7,6 A | 290 W | 76 % | 200 mA |
Little difference so combining the PA should be no problem. Combiner is a Bagley polygon. ( see GM4ISM pages.)
