Do you think this could affect on 220V (europe) voltages too? I'm sure that my house has kinda slobby voltage output.

These M8161 sure sound great, but they don't mate with GS1K's that well.
BTW, I think I'm gonna put my amp(s) (2x MKIII EU version) + all my tubes for sale in a ~month, anyone interested here? You can check my tubes from my profile.
BTW, it might have been discussed but I just ordered some Siemens 6AK5W
from Hi-Fi Tubes.
Anyone tried them?

Jezz PP, I feel like I should call up the Roto-rooter man!
Oh, and on a side note, I bent a credit card and purchased a new amp for my mini-system, the Audio Source AMP-100. Amazon for $79 and free ship. I just couldn't pass it up.
I'll drive it with my Yamaha pre-amp, with FrankenZero sourcing and the MKIII and MKIVse hanging off of tape 1 & 2. I'm going to pull the Super-T amp and look it over seriously for some upgrades/mods. Once my speakers matured, the Super-T was struggling to drive them properly.
Wait until you get that giant sack of goodies I sent you....
I was worried from day one with the line voltage being always at 126+ here.....eBoy confirming the unregulated heater voltage being out of spec...well that means a tube eater in the making....I blew through 2 sets of 6N6P-I's without really thinking to much about it....until the DR's came along (Thanks Pench for emptying my wallet of a further 170US
) Just kidding...I love these DR's......I'm glad eBoy posted his findings ...THANKS brother !!!
I have an AudioSource Rarity....it wasn't ever supposed to be sold......I have 2 hybrid Tripath class A class A/B Amp 6.3's. 150 W per channel 250 bridged mono. They are sitting here waiting for a pair of worthy near field monitors (that I will build since I can't afford a real set) on the comp desk.
That little beauty you picked up isn't a half bad amp....you can guess what I'm going to say next right ?
Send me an internal shot when you get it.....as well as the T-Amp...and see what the elves at FrankenWORKS can come up with
Congrats on the solid score...isn't that amp 50 W RMS ? I forget.

Just want to clarify the 1ohm resistor mod also applies to the MKIII and you attach it just like in your photos for the MKIV ?
Yes, this applies to MK III as well, although for MK III the board is more tight fit and harder to take out. I will post new photos when I mod my MK III this weekend.

Depends on the tube...if it's mil spec or consumer level and the amp using them....on average I would say between 1000 to 5000 hours for some types and the top shelf mil spec stuff 5000 to 10,000 hours under ideal circumstances. Too many variables to list to make a general statement of course. I always knock about 30% off max hours for a good ballpark figure.
I've had NOS tubes last 2 years + and others less than 30 days....no way to know for sure.
Hm ... that's disappointing. I would have expected (hoped for) a longer life expectancy. This makes the aforementioned mod almost a requirement.
I almost think this should be addressed at the time of production and really is a engineering flaw. Am I too harsh?
Anyone know where I can get the power tubes for a stock mkIII? I've had my amp for about 2 weeks now, but I just want to stock up on the items that can go wrong.
BTW, it might have been discussed but I just ordered some Siemens 6AK5W
from Hi-Fi Tubes.

I don't think these have been discussed here before, but I would be interested in your feedback on how they compare to the stock tubes and to the 6Zh1P-EV.
I've found these on ebay, and they are the real deal!! BIN is a decent price, so if anyone is looking for matched Sylvania 5654's with round getters and black plates, this set seems like a good deal, but it ends in 5 hours or so:

I finally got the gold plated jumpers for my MkIII, initial impression is that they take some of the harshness out of the EF92 and EF91 families of tubes, will report back with more impressions but so far the jumpers are definitely worth the cost to get the most out of your EF92/EF91 tubes.
