▦ Electro Profiler has published a book titled "Repairing Vintage Audio with My Own Hands." ▦ It contains repair know-how accompanied by abundant photographic materials. ▩ [yes24] https://www.yes24.com/product/goods/1... The volume knobs and selector buttons on old amplifiers are often contaminated, causing severe noise. In some cases, an entire channel may not work at all. When a channel does not work at all or plays very weakly, the problem is often contamination of the volume controls, not a circuit issue. With just a little attention, you can eliminate all the noise yourself. Many people spray WD40 in such situations, believing it to be a cure-all, but you absolutely must not do this. WD40 only pretends to revive electrical contacts like volume controls and switches for a moment; it will eventually clog them up and completely ruin them. You must use a dedicated contact cleaner. WD40 is not a contact cleaner. BW100 is famous and affordable as a contact cleaner, but in terms of effectiveness, Dioxit is the best. Its performance is incomparable to other contact cleaners. However, the price is exorbitant. If you have the budget, go with Dioxit!
