1003 – Start-System
There are however a few non active component blocks missing such as the resistor, capacitor, transistor, and inductor substitution blocks where any value component could be inserted into the holes in the top white cover of the block. All the original PNP transistors with bias resistors were also replaced with NPN transistors. The relay block also had a diode added across the coil to eliminate ‘chattering’. Two high quality base plates were also included.
