Hello
If you look at the pinouts of the stock 6H30PI power tube (for a little dot MK IV amplifier) and the 12ax7eh they look identical except that the 12ax7eh has a wire going to pin nine of the tube which is said to make it a 6V or 12 V heater tube. But I do not know if my little dot MK IV amplifier comes with that pin already grounded to let you use this type of 12 vote tube. So does the little dot MK IV amplifier come with this pin already grounded so that this tube would become a plug-and-play power tube. If it doesn't how hard would this be to do?
A Pinouts for the 6H30PI can be found here.
A pinouts for the 12ax7eh can be found here.
In the head FI The Reference 6SN7 Thread the review I am posting below sounds excellent.

So does all that boil down to an almost identical sounding tube to the the stock little dot IV MK SE power tube? Has anybody heard this tube? If I like the stock power tube will I like this tube and it's much cheaper price?
PS whoops I now realize what I did when I reviewed the post I just posted. I posted what is said, but about the octal version of this tube but I was looking at the nine pin mini package version when I got enthused about what could be a cheaper version of the stock power tube on eBay. Well perhaps you can tell me what you think of both I also have a pair of octal adapters just sitting there ready to use should I have to.
OK I finally think I'm getting my reviews straight between the mini nine pin version and the octal's. They seem to like the mini nine pin version@Amazon.com. Reviews to numerous to post, but here is the link. It is said to be a black Friday deal and as of this moment it is black Friday.

NEW STOCK – Electro-Harmonix EH6SN7 [PHOTO HERE]
[black plates, black base, black labels on glass, top getter]
● “The Electro Harmonix were the most dynamic in the MPX3 . The Bass is also the best and biggest of the three; quite detailed and tight. Midrange is also full of detail air and transparency up and down the range. Gets a little too bright in my system at times, but generally the most fun and involving tubes to listen to so far for me.” –bobjew
● “With the Electro Harmonix 6SN7's in current production, there is no need to suffer.” –Hirsch
● “They are fast-paced tubes with a bit of a heavy bass and ired with a slower driver tube the combo sounds quite nice.” –donovansmith
● “I came across a new 6SN7 tube by Electro-Harmonix and it sounds great. This tube seems to be a very good copy of the Sylvania VT231.It has killer bass and an excellent midrange and vocal performance. It warms up quickly and is not noisy or microphonic at all. It is an excellent value at $10.00 a pop. […] The build quality is high and they are very, very closely matched as tested on my tube tester. These get a "best buy" recommendation from Tuberoller. Try them before dropping big bucks on the Ken-Rads or CBS Brown or Red based tubes.” –Tuberoller
● “The biggest finding is that the Electro-Harmonix 6SN7 tube is about as good as a Syl 6SN7GTB.” –scottpaul_iu
NEW STOCK – Electro-Harmonix EH6SN7 Gold Pins [PHOTO HERE]
[gold pins, brown base, otherwise identical to non-gold pin version]
● “Aside from the obvious differences between the tubes– gold plated pins and the new goldish colored base; they look exactly the same. The model number is the same. The box has the same graphics with the addition of "gold pin" and printed in gold instead of black. Not surprisingly, they also sound very similar.” –bobjew
