Marblehead Audio features Restoration Kits for audio gear. Electrolytic capacitors have an estimated life of 20 years and replacing those are at the heart of our kits. But, we don’t just replace them, we upgrade them! All signal path capacitors 4.7uf or smaller get upgraded to sonically superior film caps. Time and experience has shown some older transistors are problematic or noisy. We also include replacements for those. Amplifier and Receiver kits also include the relay in most cases. Ultimate Kits for those also include new trimming resistors for the critical internal audio adjustments. The large filter caps are included with all kits unless otherwise stated in the listing.
