At about the end of this page http://www.qrp4u.de/docs/en/rf_ampl/index.htm there is a linear http://www.qrp4u.de/docs/en/rf_ampl/array-tx.gif that I have tested and works well for 40m HF band.
I have also made this little broadband linear in the past http://qrp.gr/hfamp/index.htm
I was wondering how can I make the first circuit broadband? I have tried changing the final core to a ferrite one and also removing the variable capacitor with no success.
Any advice would be useful.
