I have had for several years a BM1900-2 operating very well untill I found out that the lamps were off duty..I ordered a replacement set + rectifier from Dillon and completed the soldering successfully, I thought:after powering up there was no sound and only a couple of lamps shows light: Volume UP, Trebble,Bass, and Balance,FM4 as well as the Tuning Indication. No reaction on switching with the touch-sensors.A little measuring (I am not a well-trained electronics guy) resulted only in finding on PC board 3 (Volume UP and Down) that both L1 and L2 have 15V whereas this should be 15V and 7.9V resp'ly.Is there any thing that I can do with your long distance advice?
