A short quick upgrade for my Ceasar II Mono´s
to push the sq to the limit...
In the meantime...
As you could see in the Upgrade Part #1, the printing of the Sophia Electric Royal Princess 300B
is 90 degrees different to the Emission Labs 300B-XLS.
Not a big thing, but it´s not looking good!
Unfortunately i have only two holes for the Tube-Socket. Therefore i made two small adapter to rotate the Tube-Socket.
Now the printing faces to the front!
Perfect!
2nd Upgrade
The three grid stopper resistors will be changed from AUDIO NOTE™ 2 Watt Tantalum to Texas Components TX2575 naked Z-Foil.
After hours of burn in i must say, that there is a marginal sound difference between the 2W Tantalum and the TX2575, as expected to be honest...
Never mind... I will reinstall the Tantalums and try the TX2575 as Rk (R4 - 750R) in the MU-Stage.
