Yes, a lamp kit is available (from me) for Beomaster 1900 /1900-2 / 2300 / 2400 and 2400-2.
Many people seem to think that the panel lights are LED diodes but they are actually filament lamps and the lamps specs are
critical for correct operation. The kit contains a full set of fresh lamps (plus a spare) and comes with (dis-)assembly instructions/photos.
The lamps are soldered in so you will need basic soldering skills and electronic tools to replace the lamps.
There's a good chance that most or all of the old lamps are of the same age and if one lamp burns, others will be marginal.
Besides, the unavoidable vibrations from servicing and replacing an old lamp will most likely cause the filament in one or more
of the other old lamps to break, this is very common since the filaments get brittle with time, so I recommend replacing them all
in one go. This will also give you an equal light output.
Capacitor kits are also available for most Beomasters, Beocenters etc. (incl. the above mentioned) and highly recommended.
Send me a message for details. (Click my name "Dillen" to the left and then "start a conversation").
