Headphoneus Supremus
The MZ2 has plenty of power with the HE1000. I routinely have 1/3 more travel in the volume and if I turn it up towards max, I could use headphones as speakers. Plenty of headroom.
I leave the plexiglass off. Easier to change out tubes and it runs a little cooler though as I look at the case, it is vented all underneath and back and side so there is plenty of air flow. I have some adapters coming so I can use some VT99 tubes, equivalent to the 6SN7 but in a coke bottle shape with the grid cap. I have 4 varieties, all from the 1940's, round plate, flat and 2 other types. Back to using the 1952 Sylvania 6SN7's and Sylvania GB gold pin 6201. Great separation and more 3D.
