Power, distortion, damping are very similar. Bandwidth is wider on the SIT.

Carefully matched AB into a pair of OB Voxatives shows only small difference,
not enough to care about.

Of course that was largely the point of the SIT-2.
Mr. Pass i find France produced germanium triodes was in the 50's.

Nelson

Is the EL34 amp your creation or a store brought effort? Perhaps you could throw us "tubeophiles" a bone with a few more details....please, pretty please.

It was a relatively inexpensive Chinese unit. It is no longer available,
but you can go to:

AliExpress.com - Online Shopping for Electronics, Fashion, Home & Garden, Toys & Sports, Automobiles from China.

and search for EL34 single ended amplifiers. They start at less than $200.
