Advantages of This Kit:
1. Features a newly developed laser-cut, electrostatic powder-coated chassis (available in two colors).
2. 5 vacuum tube mounting slots, supports adapter boards for compatibility with various circuits, making future upgrades easy.
3. Dual VU meter design with an internal lining structure to prevent the meters from protruding.
4. Independent volume control for left and right channels to avoid volume differences caused by wiring.
5. Replicates a circuit designed by audio enthusiasts, with a rational design and excellent sound quality.
6. All components are imported, including Japanese Seiko capacitors, high-quality 5-band metal film resistors from Taiwan, and German Wima coupling capacitors.
7. Large-capacity inductive filtering for purer sound.
Vacuum Tube Configuration:
If assembled according to our physical point-to-point wiring diagram, the finished unit will have minimal noise and hum.
Uses a 5Z9P rectifier, a preamp driving a Shuguang 6J89 (or imported Soviet 6M8), and FU50 power tubes.
Power Output:
Class A 16W (2x8W), equivalent to 35W–75W of solid-state amplifier power.
Regarding whether it can drive your speakers: This depends on room size and personal listening volume preferences.
About power and driving capability: Tube single-ended amplifiers typically have 3W–30W output (common range). Since they operate in Class A, they have stronger load-driving capability compared to solid-state amplifiers, so even a few watts can drive speakers effectively (except for low-sensitivity speakers).
Chassis:
The chassis is CNC laser-cut and finished with electrostatic powder coating, offering superior texture and craftsmanship compared to stainless steel chassis, though at a higher cost.
Friendly Reminders:
1. DIY tube amplifier projects require some basic knowledge. We provide circuit diagrams, physical point-to-point wiring diagrams, and comprehensive technical support. With care and patience, success is achievable.
2. Our products are DIY items. The chassis is made from laser-cut stainless steel, manually bent, with side wood panels hand-sanded (wood in natural color; buyers can paint or finish as preferred). Perfect finish is challenging. For any feedback, contact customer service, and we will strive to address it.
3. This tube amplifier does not include a power cord or audio cables. Due to varying quality and personal preferences, we recommend customers source these separately.
4. Vacuum tubes are from previous-century stock, so brands may change based on inventory. Component upgrades or substitutions may occur without prior notice.
5. We inspect all components before shipping. If assembled according to the wiring diagram, the unit will produce sound. As a handmade custom product, once soldered, it is non-returnable. Purchase implies agreement.
