X'tal converter down 6 meter to 40 meter

Features

1. RF(use 6DJ8 twin triode for cascade amplifire) - MIX(6AK5) - Kathode follower(6AK5)
   6DJ8 cascade amplifire makes it high sensitivity possible, better than IC575 ICOM. Recently, 6DJ8 is used as a audio tube. But basically, this is a tube for a tuner frontend of VHF TV so that this works very well on 50MHz bands.
2. All inter-stage resonator are tuneable by voltage controled variable capacitor diode. I was afraid that the diode makes intermodulation from local station, it comes no problem.
