Looking for opinions... 1. Parasitic suppressors: Do you prefer the original Kenwood suppressors, or the newer U-shaped “hairpin” suppressors? 2. Direct grounding of the grids to the chassis, or leave as Kenwood designed in the amplifier with the RFC’s and caps? 3. Additional electrical bonding between the tuner chassis and the tube chassis, or sufficient as-is? If additional recommended, what would be your preferred way to accomplish it? 73's!
