Replacing the tubes at Little Dot2+II+

[Blackmore]

Just interesting if this easy to do so. I mean for upgrade, I guess.

I have been asking some questions about LD2+ lately, because I am interesting to buy one. But dont have any experience with the tube amps and want to be sure that this will be a right choice. Want use them with Grado RS2 /SR225
If someone have done this, please tell about it...

Thx.
