I just purchased a 112RD50 with EV speaker in showroom condition, it contains the following numbers: 82-9 (sticker on the right side of the chassis) BP-1600-EX/D (lower right side of the chassis) model: 112-RD-50 chassis: 1650-RD-EX serial number: EN10544 input: 220VAC ~50Hz. 1.1A output: 50W. RMS Is there any way to determine the revision number of the PCB inside ? I canīt find any directly on the board and according to the circuit drawings there are four exisiting REV numbers for this model. From the logic and the production time (82-9) I think it should be REV D from 01/26/82 REV E is from 01/83 and shows the "mid shift" switch, my model has the normal "clean/limiter" switch so it canīt be REV E. REV C is from 09/21/81 and REV B and A even older. So is there any way to really find out what REV # my amp is without tracing components on the PCB ? Thanks in advance for your help guys ! |
