In addition to having good sound quality, they were sold in large numbers and were well built, so much so that even today, after almost 50 years, people still talk about them and their owners like to keep them in order. Unfortunately, the technical specifications are being lost over time, which makes it difficult for the new generations of technicians to be able to maintain worthy of these products that are so significant for the Brazilian high fidelity industry. In order to help the new generations of technicians and sound box builders, we show in this video how the electrical diagram of these boxes is and we give some tips to replace the capacitors and potentiometers with problem. In addition, we show how to check the operation of the LED bar that indicates the power at which the box is working.
