which power tubes can I use in Einstein

[Kilian]

Hi,

I just wanted to know which different types of power tubes Einstein is able to handle and what the total power out would be.

I own a Einstein 100w Head with 4 EL34(I think this is Standard) > 100W

A friend of mine owns a Engl Savage 120 with two KT88 power tubes which results in 120W, why?

The Einstein 100 has up to 130 watt with EL34.
The KT88 on Your amp run with much higher plate voltage
in a different circuit.
