- Compare the specs for the new 3CX1500D7 vs the 3CX1200Z. It appears that it is a very similar tube with bigger cooler and filament designed to replace 3-500Z's. Downside is lower max frequency and gr

- You can run the amp on CW safely in the SSB mode with no problems. These amps were built when the output power limit was 1000 watts DC average input. I have operated my SB-220 on cw in the SSB mode f
