Beogram 8002 Type 5633: Electrical Restoration Tasks

I completed the electrical restoration tasks on this Beogram 8002.
The next step will be the mechanical tasks but first...here is a review of the electrical restoration work.

On the Beogram 8002 restorations a big part of the electrical work is replacing all of the electrolytic capacitors with new capacitors.  

Here is a picture of the main circuit board (PCB 1) with the microcomputer circuit board (PCB 2) before any restoration work was done.

I started with the smaller, PCB 2 assembly.
It only has one electrolytic capacitor, 2C28.  It is a 47uF, 10V electrolytic capacitor.

The Beogram 8002 boards are quite crowded and susceptible to cracks in the solder joints of the board connectors.  For that reason I always reflow the solder joints of the board connectors and on the Microcomputer Board (PCB 2) I replace the socket for the microcomputer IC.

Here is PCB 2 before the restoration.

The next few photos show the removal and restoration of the 2C28 capacitor and the IC socket for the Microcomputer.

I replaced the electrolytic capacitors on the main board (PCB 1) and reflowed the solder on the board connector solder joints next. 

I moved 1C28, a 4.7uF, 63V capacitor to the trace side of the board for more room.  It also required some repair of a PCB trace it uses.

There is one bi-polar, 27uF electrolytic capacitor in the transformer compartment that requires changing.  As the photos show, the original 4C1 capacitor was just over 20% (32.98uF) from the 27uF listed value.  I replaced it with a new capacitor assembly that measures 27.92uF.

The last two electrolytic capacitors I replaced are located on the floating chassis.  They are for the voltage regulator circuit.  There is a 47uF capacitor and a 1uF capacitor that needed replacing.

I can now move on to the mechanical restoration tasks.  Once those are complete I will be ready to test out these electrical updates.
