Great News! Starting today, the 6N2 tubes are being upgraded for free to Soviet 6H2N tubes. Limited quantity available!!! Welcome everyone to make your selections quickly!
Soviet version tube configuration: 6H2N2 + 6n1n4 + 5Z4PA1
Square meter Soviet version tube configuration: 6H2N2 + 6n1n4
In response to the strong demand from audio enthusiasts, we are launching this high-power, high-thrust push-pull tube amplifier to satisfy friends who prefer high-power tube amplifiers. As is well known, push-pull tube amplifiers offer a more comprehensive sound compared to single-ended or parallel-tube designs, excelling slightly whether in the large dynamic range required by symphonic music or the sweetness of mid-range vocals. This amplifier upholds the unique advantages of pure tube designs: ethereal and free-spirited vocals, deep and powerful bass, a vast and expansive soundstage, and a majestic, grand presence!
The knobs have been upgraded for free to premium knobs. The new knobs have essentially the same size and shape as the original ones but feature superior materials and craftsmanship. Pictures are provided below. The tube amplifier itself will not be photographed separately. Please be informed.
Regarding tube selection, this amplifier uses 6N2 tubes for the pre-stage. This tube has high amplification factor (high μ) and delivers elegant, beautiful sound! The output stage uses 6P1 tubes, which offer balanced performance across the frequency spectrum and a delightfully refined sound. The combination of these two tubes is truly a golden partnership!
For the circuit, to avoid the complicated adjustments typically required for push-pull tube amplifiers and to accommodate novice enthusiasts, our store has applied special technical treatment to the parts that normally require adjustment. This significantly reduces the difficulty of point-to-point wiring for this push-pull amplifier. Simply solder according to the diagram for perfect sound.

Friendly Reminders
1. Due to the special nature of kits, components cannot be returned or exchanged once soldered. Upon receipt, please immediately check the items. Contact customer service within 48 hours for any incorrect or missing parts. DIY tube amplifier assembly requires a certain level of foundational knowledge. Our store will provide schematics, photos, and comprehensive technical support. However, if you feel DIY might be challenging, you can purchase the finished product from our store.
2. Our store sells DIY products, which are difficult to make flawless and cannot achieve absolute perfection. If you have any opinions or suggestions, please contact customer service. We will strive to resolve any issues.
3. We will carefully pack each tube amplifier. Upon receiving the goods, please first carefully inspect the packaging. If damaged, refuse acceptance and contact our store promptly. Otherwise, we will be unable to assist.
4. This tube amplifier does not include a power cord or audio cables.
5. The tube amplifier MUST be connected to speakers before powering on. This is because the tube amplifier's output transformer requires a load; otherwise, it is very easy to burn out the output transformer!
6. Placing an order indicates your agreement to the above terms and conditions.
