I have a home made feed with 6 volt I have use it only a few time with my old atmy and it is working fine, my atmys have never worked so well with the original PT from factory, my idea it to give more power to the original PT just to see if it gets better,any way I don't care too much about the 901 if they die because I ve switched from 901 to 510 but I want to wear they out.
I just wanted to know if someone has do it before.
