so the sound fades in and out when you poke the power supply pcb; does that suggest that capacative storage is feeding the amp after your poking has disrupted the DC rail supply?
lift the complete tuner tray off to get topside access
Ya, all the lamps are controlled from selector except the power metersFor now, just so that I can see just which lamps are not faulty I have performed the illumination mod. From what I can see, all the scale bulbs seem to be working (yes?) as do the signal meters. As already identified and mentioned, one in each of the power meters lamps are not working. But what about the individual input selection ID lamps - FM, AM, AUX etc? - will they only work when I get the selection switch working?
Ok thanks, exactly what level of, and procedure of dismantlement is that?
I believe it's identical to the DB version. If so there are eight screws (two are hidden at each and of the lamphouse) holding the tuner tray to the chassis. There are also two countersunk screws fastening the faceplate top edge to the tray. Pull off the tuner knob and disconnect the various plugs and sockets. Slide the tray rearwards sufficiently to allow it to be lifted so that the ground connection of the RF 12v supply board can be disconnected from under the tray..

no, the selector lamps still should function as normal..Ok thanks, but having done the illumination mod, I'm not sure if the input selection ID lamps should have all illuminated too?
