Solid State 3TF7 Ballast tube for Collins R-390 and others

Description: Offered here is a solid state current regulator to replace the 3TF7 ballast tube in the R-390 and other receivers. It regulates AC heater current to a nearly constant 300 mA using a modern linear regulator IC. the I've sold many of these in the past and have recently started building them again due to a recent request. Note: I have been told that these will not work with the R-725
