- On low pass filters, what would be a good suggested Q for the design? Opinions vary somewhat so what is the folks heres suggestions? The reason being, since the talk of solid state came up, I'm tinke

- Unless you plan to modulate that amplifier, you will need bias for AM service (amplification of low level AM). If you don't bias it to at least AB you will have a disaster on your hands. 73, ... Joe,

- Greetings all, What voltage rating should be used for the caps in low pass filters following a 600 watt solid state amp? How about a KW amp? The LPFs are 5 or 7 pole Chebycheff designs just like the

- Tony, The problem isn?t going to be so much the voltage as the current. The impedance of the filter is going to be 50 ohms. That alone will keep the voltage under tow. The current through the filter

- The impedance of the filter is going to be 50 ohms. That alone will keep the voltage under tow. The current through the filter however will be substantial. If the actual power is 600 watts average an

- Hello Bob, Would something like this fit the bill? http://www.w8zr.net/eztuner/index.htm Also, your friend that is building the EB1-4 600W SS Amps, what is he doing for an attenuator for the input? A

- Duane, My buddy abruptly stopped working on that project. He apparently got busy with too many irons in too many fires. He wasn?t planning on using an attenuator, just more modules. :-) I don?t know
