The MkIII is a great pre-amp by all accounts. Replacing/upgrading the driver tubes from stock will also help you be able to tune the pre-amp to your exact preference (the preamp out is driven solely by the driver tubes).

X2! It is a great Pre-amp for sure. DoA, check this out from DavidZ on the LD site:

"To answer your question, actually all of the MK series amplifiers with pre-amplifier functionality (MK 2, MK 3, MK 4, and MK 4 SE) have the pre-amp signal routed through both the driver and power tubes." Post (#939)

I didn't know this either (until I found it), but some quick power tube swapping while using the pre-out to my T-amp, confirms this!

Now I understand why it sounds so good.

Mmmm this amp sounds great, I can confirm that from my own "testing"

I received a MK III today.
But I have a problem when I met the highest volume.
The volume decreases slightly, it does not ?

(setting gain: 10)

Not so. The preamp uses all 4 tubes. See the manual.

If you mean to change it to the 6H30PI, yes, you need the mod first. I would give the 6H6N-PI a chance first. It is really a nice sounding power tube. The driver tube rolling possibilities are great and net the most changes.

Would you say that placing other driver tubes besides the stock ones will make it sound BETTER or just DIFFERENT? EX: I have a NOS set of Tung-Sol's I just found on Ebay. If they will make the amp better, I'd rather do the burn in process with them first. (Amp should be here today)

Ow, well, it really doesn't matter in the end. Most folks like to burn-in with the original set, so they have a "default" reference. Then they roll to explore the changes. The Tung-Sols will sound better, once they are burned in too.

Considering that every tube set you put in the amp will need to be burned in, they will eventually get their 40-45 hours in the socket at some point. Those demanding tubes! They want their moment in the spotlight!

So the tubes only need about 50 hours? That's not so bad, I read your review as +/- 144 hours, but I guess that was for the amp (capacitors, etc) only, right?

Correct. The unit will be around 100-145, but tubes usually take only 40-45.

so the stock power tube is good enough, right ? if change with 6H30PI, it will be change the amp character ?
