Hi Wonder if the group can point me in the right direction ? I am building a GS-35B Amplifier for the HF bands and wanted to use a Fixed (tapped) coil in the pi-tank rather than a roller inductor. Does anyone know of a published (on the web) design of a GS-35B amp for HF with a fixed tapped coil in the output ? Thanks in anticipation Iain G4DPF
