Later this is polished too, for pure optical reason.
This nameplate is also made by TechGraphix.
| Over 80 hours work to mill this 40 kilo block of aluminum. About 30 kilos of aluminum-chips (= waiste) was the result. |
|
The "Artist impression" of the final result. One of the newest and fastest servers still had two days work on this picture. This picture is also "drawn" by TechGraphix. |
|
| Drilling a few horizontal holes and tap threads to mount some of the components. |
|
The final result of this Dutch product: 50 kilogrammes top-technology. |
|
| Days of sanding and polishing to wipe out all the traces of machining. After that the frame was sandblasted to get a nice surfacestructure. |
|
Another nice view. On the floor, in front of one of the Klipshorn-speakers. The wooden horns, as decoration, are also made by TechGraphix. |
|
| The necesary Lathe-machining. Here still a dull surface. To see the difference the decorative ring for the 300B-tube is polished. |
|
Adjustments for the tubes reside just under the nameplate. The current can be read-off digitaly. With the switch, both tubes can be selected. |
|
| Before the frame was anodised all metal parts where checked to fit well. Really a nice view. |
|
Thick silver wires are laid in the canals which are milled out of the teflon plate. After the wires where wrapped in teflontape they fitted exactly. |
|
|
A silversmith made this
central-earthpoint from 99,999% pure silver. Later this is polished too, for pure optical reason. |
|
A few of the used PCB's: The Delay/Bias/meter PCB, the rectifiers for the auxiliary voltages and the voltage controlled currentsources. |
|
|
Made from a 10mm thick
brass plat. On the backside the cut-away for the meter and switch.
This nameplate is also made by TechGraphix. |
|
A view at the inside of the amplifier. Many costly components like Blackgate, Mundorf and Tantal resistors. All wiring is 99,999% silver...... |
|
| A huge plate of 12mm thick teflon is machine to a real piece of art. Almost too beautifull to treat it with formaldehyde (to obtain a good bond with a special kit ) |
|
Under the T-bridge is a teflon-sheet as the WKZ-highvoltage- capacitors come very close to the bottomplate. |
|
| The plate fits exactly in the frame. All holes correspond perfect, Thé advantages of CAD-CAM. |
|
With the bottomplate attached it is hardly visible. Here still in the wooden Assembly-Transport- and adjustment crate in which the amplifier can be placed upside-down . |
|
| First modification: The input is balanced now and all signalwiring to the first tube is gold with cotton and leather. |
|
Second modification: Rewiring of the rectifiertube-socket for the Philips EY500 tube. |
