Hello QH, this is an update of my order step by step : I sent to you a total of 840.00 for Option 1,2,3,4 that detail like this 400 for DAC module, 150 for DAC controller, 60 for amanero module, 60 for transformer, 60 for iv output and Hv power supply plus 70 for shipping making a total of 800 dollars (400+150+60+60+70=800+16(paypal fee) =816.00 then because your not shipping the amanero module I have a balance of 84.00 dollars . Then I do not know if IV ouput and HV power supply is the same as super IV , I would like to have the best . Do I need to send more money?

Hello QH, I just received my chassis four days ago but just today noticed that DAC module and controller where inside chassis, but only one transformer when I ordered two? Now I'm confuse, do I need two or just one transformer. Any update about the latest tube output and hv power supply (still waiting for boards).

I read again all 14 pages of the manual kit , says nothing special about turn on or off .........

so basically i connect it to mains , and it should work , however my display stays in stand bye mode all the time and wont change ...............

doesnt respond to turning the on/off switch ( rotary encoder )
or remote control

any suggestions .........

when i plug it in the display briefly lights up , text is displayed , then it shuts down ,and that was it
