Surface treatment, a total of seven steps. 1, the surface de-oxidation
2, the surface to the oil
3, the surface texture of the handle
4, the second to oil
5, anodizing
6, surface passivation
7, closed
The figure below the surface texture process ..........................

Good wood frame holds the aluminum plate to be machined on CNC groove

Winding is the most troublesome thing, but fortunately there are CNC winding machine, programmed, each end, automatic stop waiting pad of paper. Save a lot of labor.

Welding is just the final step, about 2-3% of the entire production process, usually 2-3 hours on the completion.
PCB CNC machining flat welding row is prefabricated. In addition to pre-existing devices in all AF250 wire connection, in order to increase its reliability.
Flat welding transformer next row for leading multi-channel high voltage winding voltage to facilitate debugging. After the completion of the power section, the actual current load test first, then leave for 1-2 hours. Observed temperature rise during power cattle.

Hi,
there is something wrong with your schematic. First EC88 work with 1.8mA (200v-160v = 40V/22Kohm = 1.8mA). Your Rk is 150 Ohm+47 Ohm = 197 Ohm. So your bias point should be 197 Ohm x 1.8mA = 0.36V! Not 1V.
If you look EC88 datasheet (http://www.mif.pg.gda.pl/homepages/frank/sheets/030/e/EC88.pdf) the bias at 160V (anode) and 1.8mA should be around 2.6-2.7V.
Thanks for your attentive correct, there are marked wrong place. It has been corrected.
