CRT Board BOM UpdatesJune 21, 2014 3:18 pm Uncategorized
I have corrected some mistakes in the bills of materials for the CRT driver boards (the files in GitHub have already been updated):
- ScopePower U2 part number from TS271CN (DIP package) to TS271IDT (SOIC).
- ScopePower R3 part number from VR37000003305JR500 (33 meg) to VR37000001005JR500 (10 meg).
If you already ordered parts, I apologize. The TS271CN is a great little op amp and the DIP package version will work fine in a breadboard. That’s what I will do with the ones I accidentally ordered. The 33 meg resistor is useful as a bleeder resistor if you build the post deflection acceleration module (to be posted soon).
