Vintage Tube Amp

This is quality American made hardware made before Lafayette went Japanese sourced. It features high-end audio design cues including output transformers heavy on the iron, four EL86 power output tubes rated 50 Watts from two channels, two 7199 tube gain stages and phase splitter, 12AX7 pre-amplifier stages, and a hum-free DC filament supply. This particular’Made In USA tube stereo amplifier was found unmodified from from its original design but badly in need of repair. An experienced electronic engineer repaired and corrected the electrical faults and replaced the defective circuit elements. This included replacing all electrolytic capacitors and critical high voltage coupling tone capacitors plus other out of tolerance components. All tubes were tested and the weak and defective ones were replaced. The balance and quiescent plate current for each of the push-pull outputs was then adjusted according to factory specs. All switches were cleaned with Deoxit D5 and pots cleaned and lubricated with Deoxit F5. Some panel knobs were replaced. A new power cord was installed with a polarized plug. The chassis, case and cover were dusted and cleaned to remove years of dirt and grime as best as possible and the front panel is amazingly crisp and markings brilliant considering it is nearly 65 years old. All this resulted in a Stereo amplifier that delivers great tube performance. The warm glow of the tube filaments and neon pilot lamp conjure thoughts of nostalgia and the sound is pure sonic joy. And don’t you just love the retro angled feet. It is ready to be your daily listen for hopefully another 65 years. Copy of original Lafayette Electronics User Instructions will be included.
