I have gotten the cover back on my Johnson Thunderbolt and am pleased with its operation on 160 and up to 10 meters.  The modification of adding another tank coil and russian vacuum relay / disc capacitor is preforming well on the top band.  The HV power supply I built has a solid state relay to switch it on during operation saving heat in the shack and makes the rig very satisfying to operate.  Previously the factory design had over 200 watts of bleeder resistor stand-by losses, PHEW.

Now I am looking for a complete Johnson THUNDERBOLT 6N2 amp to complete the shack and hope this forum may offer some leads.  Ebay has a pair but I have not gotten information on their condition, only one photo.  Any and all assistance would be greatly appreciated, thank you. Woody N4MQ
