The sizzle crap is a symptom of a defective CCS.

Vacuum tubes are pretty rugged compared to solid state devices, which won't stand any abuse.

  Thanx Dave,
  
  I now have a channel out. I have noticed the spooky nature of our SS friends ..those who load soo artfully...not sure they're worth the trouble. I'm looking at choke prices....

    The only problems I've had with DN2540N5-based CCSs have been overvoltage failure and overheat failure. The overvoltage problem has been virtually eliminated with the use of the 1000v IXYS MOSFETs and the overheat problems shouldn't be an issue with careful engineering. However, I'm quite happy to sell you plate chokes if you want them. ;=))

      Kevin,
      
      Thanks..I'm impressed with the personality of these devices. I've had instances where a channel stops loading and I'll pull it out, apply a 9 v battery and it comes back to life, I lost a channel last enening after an extended listening session. The channel comes back after cool down. I'm running 3 watts with a small sink.
      
      At the end of the day, the ability of the these devices to load a valve is incredible. I like to tinker...I'll hold off on the chokes for now ;> }.
      
      Does the IXYS device offer any sonic differences?

        3 watts with a small heat sink in free air is fine. Inside a chassis, it's probably a bit under sunk. That could be your issue. The IXYS devices are clearly superior from a sonic standpoint. That's why when I had auditioned them, I changed the kit to feature the IXYS device.

      Finally, the salesman in Kevin comes out, albeit with some cajoling needed after all these years...
