Bat 150 SE replacing 6C33-B power tubes problems

I like to thank everyone for their advice about the 6C33-B power tubes promblems that I was having.
300 music hours have now passed both amps are singing like I have never heard before, just amazing what new tubes can do. I would like to mention that Kevin Deal suggested that I clean the pins of each tube with grade 400 sandpaper and by applying a thin film of Walker SST contact enhancer really helps.
All eight new tubes glow at the same brightness also, since some of them used to be deep red on the large vertical black plate.

Hi Terry,

I'm glad to hear all is well with your BAT 150se monoblock amps. I did however want to give you a word of caution about applying the Walker SST or similar type of products on the tube pins. There have been many reported problems of this causing tubes to fail and taking the amp with them in the process. I have NOT heard of this being a problem with BAT tube amps but I do feel a phone call to BAT to inquire about this would be reasonable.

All the best,
Tom

Hi Tom, thank you for the heads up. I have contacted BAT about the SST and their response is 'use at your own risk/void warranty'.
SST appears to act as conductor between contacts and since it is in paste form it can also create electrical shorts if it gets in contact with any other components especially the high voltage parts as explained to me by my supplier. I have been using this product to treat interconnect and speaker connections.(low voltage) and just started with the tubes. I think the way the application of the SST is made is extremely important. As mentioned I touch the tube pins forming a tiny dot without creating any drips and never painting the entire pin. I will post any problems created by the Walker SST.
