Beomaster 1900 (Type 2903): New Arrival

After a long series of Beogram projects I have a change of pace with a nice Beomaster 1900 receiver sent to us for restoration.

The AC plug is missing so no turning the unit on for any type of checks. I will give the unit a quick survey to see if anything major jumps out at me.






















Turning it over I can see that it is missing its rubber feet.



Over all it looks great so far. Time to take a peek inside.

























Nothing major but I do see that the bass, treble and balance indicator masks have some wear on them.
The bass and balance have bad enough wear to the point that the masks really need replacing. I will try to find replacements or print some of my own. The treble mask is in good enough shape that it could be used as a template to copy from.






















Here are the Beomaster indicator lamps. I will get the receiver working again before looking at replacement options for the lamps. LED replacement is an option but some of the lamps are integral to their circuit operation so any replacement there will require more than just an LED and a load resistor.
























Next step is to check my 105°C electrolytic capacitor stock to see what I have and what I need to order in recapping this Beomaster.

  1. I acquired a Beomaster 1900 Type 2904 yesterday for $100 but will return or negotiate much lower price. When I plug it in and turn it on the standby light comes on but when I press phono, tape or any of the FM buttons, a red arrow on the left lights up along with a red square over whichever function button is being pressed and I can hear a solenoid click. A buzz can also be heard through the right headphone. This is all very brief, as the solenoid immediately clicks back off and the lights go out. If I hold any of the buttons down, the solenoid rapidly clicks repeatedly and the lights only come on briefly with the first click. I have to wait about 5 seconds between button presses to get the lights to come on as if it was the first press of a button. Fully functioning (but not restored) units go for $100-$150 on ebay. I don't know if any of this helps you but do you have any advise, as I can return it today?
    -Also, I purchased a Beogram 4002 last weekend and wanted to let you know your YouTube videos have been extremely helpful!

  2. Hi Jeff,

    I have purchased quite a few audio components from Ebay over the years. My expectations on those purchases are usually that I will have to do a restoration on them as even the items advertised as working have no guarantee that they will remain in that condition. In most cases the items have had numerous owners and the service history is unknown. If the physical condition of the Beomaster is really good I would weigh that in deciding to keep it or not. However, since it isn't as advertised I would ask for a partial refund.
    I hope that helps.
