About the CRT main supply 2 PCB

CRT main supply 2 is an open source PCB design by Thinkpad4by3, published on GitHub. It is a 2-layer board measuring 100 × 100 mm, with 103 components from 75 distinct parts.

Other key parts include the LM5155DSSR, TLV314QDBVR, PC817, TL431DBZ and AP2204K-5.0. By type, the board carries 33 resistors, 32 capacitors, 11 diodes, 10 connectors, 7 ICs and 4 transformers.

From the project

Electrostatic CRT driver designed from the ground up for performance, versatility and ease-of-manufacturability

The 2nd board is the deflection board, which consists of all the required components to take any sort of vector control X/Y signal and amplify it to the +/- 150V required to move the beam around. This board is compatible with almost every type of ES-CRT, including single ended deflection type tubes. All plates are driven by 300Vpk-pk 500KHz bandwidth amplifiers, where gain/offset can be used to control picture size, and neutral voltage can set for astigmatism. Amplifiers are of a class-AB variety, and are closed loop for minimal distortion, and are powered by their own local bi-polar power…
