Bat 150 SE replacing 6C33-B power tubes problems

FWIW there are no 'current production' 6C33s- they are all NOS. The factory that made them was dismantled about 3 years or so ago.

When 6C33B's blew in my VK-60s, the fuses never saved some conponents from getting fried. This happened on 3 different occaisions.
Good luck!

Thank you all for this info.
The sparks were inside the new power tubes that blew the 3 amps fuses. The amps suffer no damages. Guess I very am lucky. With the old original BAT factory tubes the sound is normal and sweet. However, several of the old tubes would not allow the green LED to stay on reason being why I had to have them replaced. I have about 8 hrs on the new set, so I will just keep the breakin going. After cleaning the pins with 400 sandpaper a bit of improvement is heard.
Jfrech, can you tell me which are the input tubes and can you suggest what type and make of others tube so I try some tube rolling.
I was not aware that the power tubes are no longer made. This a concern for BAT owners. Are ther any other suppliers around ?

Hello Terry,

Sorry to hear about your problem. Yes the 6c33 tube can be a pain in the neck sometimes but BAT has done a good job of seeing to it that the amp is well protected.

From what I've heard there is a HUGE supply of these tubes so there is no need to worry about a shortage for a very long time. I'm sure the amps will be sounding as good as ever in no time.

Best of luck,
Tom

I have RCA red base 5692's in the 6sn7 spots in my 75se. Much sweeter sound. Also I replaced the 6v6, but can't remember the actual tube.

Good luck !
