- Hello all Trying to decide between a "Pi" and a "Tee" input circuit, for a 50Mhz single 3-400Z amp. (formerly AL-80A with 3-400Z and not the 3-500Z). Any thoughts please? Thanks in advance, Isaac, 4Z

- Hi Carl, Thanks. I thought a "Tee" would be easy to tune outside the amp in real time (one cap), and would basically achieve the same result as the "Pi". Someone elsewhere mentioned better harmonic t

- Hello all Many thanks to all who replied and educated me. One thing is sure now, I have decided on the "Pi" for input. Now if anyone has a good source for a 3-30 pf 5-7Kv vacuum, or wants to depart w

- Hi Jim The choke is a home-made replica (quite close) of the original stock. I wounded it myself, but never evaluated it with a Dip meter. (I counted turns, measured spacings, wire diameter & inducta
