How to increase current capability without changing R1 (2M) or R2 (1M) in LED circuit?

The discussion centers on increasing the current capability of a high voltage sensor circuit without altering the resistor values R1 (2MΩ) and R2 (1MΩ). The circuit uses DIACs as triggering elements, each with a firing voltage around 26 V, arranged in multiple paths including a 75 V path (three DIACs in series) and a 28 V path (one DIAC and three LEDs). The main challenge is that high resistance limits holding current, causing DIACs to turn off prematurely, resembling a relaxation oscillator. Suggestions to increase current by lowering resistor values were rejected to maintain circuit function and secrecy. The exact current increase target is approximately 25%. The lack of a detailed circuit diagram and the secretive nature of the design complicate providing specific solutions. The discussion highlights the need to understand the source current capability and the firing voltages of DIACs to propose effective current amplification methods without compromising the circuit’s intended operation.
