Hi to all Tubes friends,

i want to introduce you today my finished HighEnd Mono-Block project.

It based on the circuit of the netherlands Tube Guru Triode Dick, the "Ceasar II".

To the components:

The Output-, Chocke- and Powertransformers are from AE-Europe and were build, developed and optimized in cooperation with Triode Dick.
To push the top quality of the OTīs, i have ordered them with silver wire on the secondary side.

The design of the 4mm natural anodized aluminum panels comes from my "mind" and were build from Schaeffer in Berlin.

Because i donīt have the faintest idea of woodwork, my good friend John Eekels helped me and build some wonderful cabinets fo my project. As always he made a perfect job!
Thanks again at this point.

Now to the tubes:

For the 300B Tube there were only one tube in my mind, the Emission Labs EML 300B-XLS. This tube made a perfect job for months in my Woo Audio WA5-LE headphone amp and is one of the best 300Bīs on the planet.
You could get it from JAC Music. If you have questions about it, Jac van de Walle from JAC Music is a great specialist about Tube questions.

The D3a Tube, exclusiv build for the former German Post, you could get quite well at ebay ect.

As 6N30P i use an original russian REFLECTOR "DR" version. It is build exclusive for the russian army.

For the rectifier tube Triode Dick provided normally a GZ37 or a GZ34.
At this point i selected one of the most recommended rectifiers for my Monoīs, the NOS Mullard High Wycombe CV378 (GZ37 "Fat Glass / Coke Bottle".

The remaining parts are selected within my HighEnd thoughts.

Capacitors: Mundorf Tube Caps (Power Supply), Mundorf Silver/Gold/Oil (Input Stage)

Resistors: Audio Note Tantalum 2W (Signal path), Kiwame for the rest
