Gustav,

I just remembered one thing about these cells...
In order to get these to make contact in the power tubes you will need to remove a very small portion of the shrink wrap on the negative end of the cell. An exacto knife will do the trick. Just hold the knife in place and spin the cell to cut the plastic wrap. Its not hard to do at all, pm me if you need help.

If you get these from Pete, they should already be done this way.
