Your circuit's running hot and that carbon film resistor's about to drift out of spec. Swap it for a wire wound 1K0 rated at 5 watts continuous. Jaycar makes these in-house, so you're getting a consistent value, not a lottery ticket from a marketplace listing. One piece, sold separately. Grab the exact value your schematic calls for and get back to building
