...and put me down for a pair if you think about selling them. My current ones have remnants of burnt sennheiser pads on them
Thanks.

I ended up getting some of these, which appear to be identical to the ones shipped with my amp.

Sometime one just have to take in a few moment to realise the magnitude of the situation. That "moment" for me was when I got my Tung-sol "black plate" 5654.

Expecting your normal 60's, 70's tube. I was floored when the packaged arrived. That indeed is 1951 on that box. 57 years since its been fired up. More then half a century!!! Even the box smells like my grandfather For those with a keen eye, its also got 1-43 printed on it too. So it could be even older! Another bonus is that its the military JAN version(Oohh how sweet it feels!). This thing is MAGIC, sorry but the M8100 has nothing on these out of the box.

So anyone with moments like these with your tubes?

I have. I bought some Arcturus 5687's tubes for my MKIVse. Right out of the box, OMG! Sound like you can only get from old Tung-sol's or Amperex Bugle Boys. Finding great tubes can be quite enjoyable !!!

I just ordered some Tung-sol 5654/EF95 black plate tubes! Glad to know that you're impressed with them. I've been extremely impressed with the stock setup but reading about others having a good experience rolling in tubes pushed me to try it out. I also have a pair of Amperex EF92 on the way. At home I already I have the stock MKIII GE tubes as well as Mullard CV131 tubes. Once I get the two new pairs, I plan to do a comparison of all of them.

There are a lot of options.

My only gripe, and it's minor, is the jumpers. I wish there was a switch. I imagine it's made without a switch so that you can't accidentally set the amp incorrectly. It takes a deliberate action to set it up.

Yesterday I took some EF92 Mullards to work to try out in the amp. I brought the tubes, jumpers, and a pair of tweezers to install them. I grabbed one jumper with the tweezers and -ZING- it shot across the room never to be seen again. Luckily our IT department had a bunch of spares. But it's still a pain. I suppose I'll use some needle-nose pliers next time to get a better grip....

...or install my own switch. It would be simple enough to solder wires to the four pins and attach a single on-off switch. Just have to figure out where to mount it.

If they anything like mine then Its pretty much the cherry on top! How do they get such sound way back then IMO the setup now is on par with the MKIVse in sound with the 6H6NPi + Tungsol. Hey Penchum thats your cue for a comparison! Completely content right now even with only 25hr burn in

Well, once my MKIII gets here, and I give it some hours, I'll be posting for sure. I'll be doing a full review as well. Another interesting comparison would be the MKII with same tubes as the MKIII. Might as well run the scope of things up and down the ladder!

If only you got a regular MKIV, then it will be a full house comparison.

Arcturus. Now thats a blast from the past indeed. They where famous for having "blue" tubes right?

BTW. How did you go with the laser heat test, any valid results?
