***UPDATE: New PM-2500 Kit for the Dentron MLA-2500 Development Nearly Complete***
15 December 2013: Development of the new PM-2500 kit for the Dentron MLA-2500 and MLA-2500B amps is nearly complete! The kit will contain a new rectifier/control board and a new filter capacitor board. The control board uses a pre-programmed PIC chip and a MOSFET to replace the time delay tube. A new RLY2 and socket will also be included in the kit along with all other discrete components. It looks as if one kit will be compatible with both the MLA-2500 and MLA-2500B amps. The first prototype boards have been submitted for manufacturing. I will be looking for a couple beta testers soon. If you are interested, please let me know. 73, Jeff W8CQ
