I use a katodefollower because the GU81M takes at G1 by -10V around 10mA grindcurrent ...

With the author's permission, I would like to open this thread to get some insight on the possibility of replicating this amp:
To adequately do so I really need to know impedance and characteristics of the final and interstage transformer.
The author has been very very kind in providing me with some info:
The amp works with these conditions:
The interstage transformer has a gear ratio of 1:2. and an ultralinear tap of 50%.
The output transformer has a prim. 5kOhm and two 20% tap for negative feedback, also and sec. 8Ohm/4Ohm.
Unfortunately I do not posess simulation software nor would I trust myself in designing such a complex design.
If anyone is able to help me out in replicating this design I would be very grateful!
Also if it were possible to eliminate the interstage transformer (or at leasr find an equivalent of commercial production) it would simplify the work greatly.
