So I have a JJ ECC99 in my hd2 atm and i was wondering what other output tubes would work?I heard the 12bh7 works and a 6n6p, is that true are there any others? I am willing to do some mods also if need be. i have a telefunken 12ax7 smooth in as input tube. any info would be apreciated thanks.

You can not use a 6n6p because it needs 6.3 volts on the heaters and the HD2 works with 12.3v . In the case of the 12bh7, you can plug it in and nothing bad will happen but the ecc99 works better in that amplifier.
