Do you have a link for the schematic or a link to a DIY forum discussion? Alot of people buy an E12 to stop those spikes but that seems expensive for some of the budget DIY projects out there. So if your suggestion does the job it would be cool. (Just need more info before I try it!) Hey Samarai1200, can you elaborate on your post?

Most will likely have a 12-13V power supply kicking around so you can do this real cheap.

I have never tried a tube at low voltage but I have seen it done several times before.<br><br>cheers,<br>gio you are welcome.
