@gyraf : what a great hint with the PF86. Thank you so much. Again. I ll go this way. Could find a good bunch of Siemens PF 86 them for 6€. I bought a few and will try them.
@jensenmann : Thanks for sorting this out per PM.
@Heikki : Totally right, this all works flawless. The point is the JJ 806s itself. They are noisy more often as accaptable and I am still trying to keep the cost of the project low as possible. Out of 8 tubes 24€ / piece 2 were not useable because they were noisy.
