Hi Alexey, I'm planning to use a single 15V LT3045-A board to power a pair of active crossovers that drive my subwoofer(s) and stereo power amp to main speakers (https://www.xkitz.com/collections/active-crossovers-and-bi-amplifiers-1/products/linkwitz-riley-2-way-active-crossover-fully-assembled-xover-2?variant=5286065569825). Each (100mA) crossover has an on-board LM317DCYR voltage regulator which is implemented as shown below: The 15V output of the LT3045-A will be connected to VIN and GND. To bypass the LM317DCYR I was advised to short pin 3 and pin 2. Should I also remove resistors R63 and R64, caps C15 and C65, and any other capacitors across VIN and GND? Thanks.
