Geom.Astig TVM852 REV.A Circuit Board

Analog signal conditioning and correction board, likely used in CRT display systems or test instrumentation for beam shaping, image focus, and geometry correction. Board ID: TVM852 REV.A Markings: GEOM., ASTIG., FOCUS, VOLTAGE, SECTION A 137784 Function: Analog adjustment and signal routing for electron beam geometry and astigmatism correction Features: – Multi-turn trimpots for precise analog calibration (e.g. focus, centering) – Multiple power MOSFETs and op-amps – Red epoxy-dipped capacitors for high-frequency stability – Pin headers for I/O and backplane integration – Differential signal filtering and shaping – Labeled test points (TP3, TP5) – Likely part of a multi-board system (e.g., with TVM851) Application: Used in CRT-based systems (oscilloscopes, radar displays, professional video monitors) to fine-tune image geometry and beam focus.
