As noted, mine already has the linear power supply, so my guess is that it is OK. I suspect that the Molex plug that connects the power supply transformer to the circuit board had gone bad. Happened back in 2021 and I fixed it myself. This time Ive decided to send the unit to the repair shop and have asked them, if it is the plug, to direct solder the wires. I also figure a general health check on the unit couldn’t hurt.
