Sorry for presenting my contact data as an image.|
I hope this will reduce the amount of SPAM.
If you send me a mail: Please give me a valid email return address|
and preferably your first AND second/family name. There are so many John's;-)
If you need a datasheet, please provide me with as much data as possible.|
Just a tube type number is often difficult to find. The brand name helps a lot.
If you don't have a brand name, please add a good description.
[ I have a lot of data but far from all;-) ]
