My Yaesu FL2100B is in dire need of new 572B tubes, the output is down to 200W. Which is the best way go, Svetlana, Taylor or Cetron?

I put svetlana 572b's in my clipperton L amp. They work well NOW. At first they had a problem with oscillation on 20-15-10 M. I did a little work with the supressors and got it under control on all but 10 M. The svetlana tubes are higher gain and have a higher plate dissipation. Bob alper at Svetlana was very helpfull and I was very happy with their customer service. They have a number of technical publications for different amps using the svetlana tubes. 73 -adam
