I've had some time to read the manual and play with the 'scope. It seems to work. I am pleased with the deal. I've figured out most of the front panel button functions. I'll need to get a waveform

Re: 556 On E-Bay
Pretty nice looking example of a 556. If I had the room, I never would have gotten rid of my last one. The quality of the trace is incredible... It was that or my best ol' favorite 555 with the P7 CRT

Re: DC504 counter display
maybe it's time to make an adapter board. Since the height is a close fit, could you cut out the area of the PCB where the row of LED digits is and solder the adapter PCB in there on the back? if so,

Immediately above and offset to the right of the "f" key in the middle of the keyboard is a button marked "SCOPE" in the section marked "CRT DISPLAY". It is usually the first button I press when

Re: Tek 422 HV power supply issues
A little more investigation showed the blanking levels did not match the waveform diagrams; putting a meter on the +55 showed +66, so now it's on to the LV ps. Anyone have a schematic or link to a 422
