Got them separate. No kit, just plane copying the schematic and the board. Pretty sure it's the right one. It is the TO-220AB package. Also, I got my hands on the college scope, and measured it right this time. 11.5volts on the 555 output (12v input), 30kHz, really nice square waveform. > Try disconnecting the diode on your breadboard and applying a 12V DC > to the output node (where you expect 170V) and see what voltage you > measure at the base of Q2.

I can't measure the voltage between the base and the emitter on Q2 yet. Don't want to put in another FET and burn it like the other 3. I want it to be the last thing. So I would say that the problem really is in the cheap chinese components! And hopefully, I will get a replacement soon! :) And just one question. I checked the shipping prices from Mouser and Digi-key. They were both between $100 and $120 for a single item. Is it always like this (I am in Europe). -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
