Tony, One other thing. A valiant can put out 150 watts of AM carrier, and a T-Bolt should be able to put out 400 watts when the 4-400's are running flat out at maximum plate dissipation (back to that 33% efficiency again of AM linear amps). If you back off the T-Bolt to ease the burden on the tubes, then maybe 300 watts output. So this approach gives you 3 db power boost above the Valiant. Consider that even if you de-tune the valiant to 75 watts out, you still need to get down somewhere into single digit watts to drive the T-Bolt. Looks like a 10 db, or more pad is required. Is all this trouble worth it to you? An AM rig with a single 6146, or 2e26 in the output may be a better approach to drive the T-Bolt. Good luck with your project.. Jim
