To disassemble the cabinet is fairly easy. You lift the top half of the case off first by unscrewing two philips head screws located under the top handle. The top half should then lift off. You can then access the telescopic antenna. You then can then see four philips head screws holding the chassis to the bottom half of the case inside on four corners of the chassis. Also unscrew the headphone jack nut at the bottom of the case. Undo those and the bottom half of the case can be removed. The front panel is held to the chassis by four philips head screws. Remove the knobs undo the screws and unscrew the microphone socket nut and the front panel will come off giving access to the lamps. Normally the power lamp and the FM stereo lamp is blown on these. The best way to get the right globe for these is to measure the voltage across the leads. I have seen some variations in voltages on these depending on build models. They used those grain of wheat style bulbs. I used grommets to remount replacements in the ones I have repaired as the originals had rubber mounts that are usually deteriorated with age.BOB BONCHAK wrote:
Interesting that the Sams TSM 131 (transistor service manual) data does not contain the disassembly information or the lamp specifications.▲ http://www.antiqueradios.com/forums/vie ... 9#p1519689
Sams also produced a photofact for your model 2004 in 1975
no doubt it would also contain little or no disassembly instructions and at $22.00 ...wellhttps://www.samswebsite.com/en/photofac ... mit=Search
Just wiggle them by grabbing the old white grommets/rubber mounts with long-nosed pliers and pull them out.
Like the good dentist, be firm but gentle.
If you have any trouble tracking down the grain of wheat lamps, let us know.
Someone may give you some guidance as to replacing these with LED's as the grain of wheat lamps are notorious for not lasting very long...
oh... Great photos
