This leads to situations where our customers, when ordering sets of tubes following the technical specifications of the amplifier, receive unsuitable tubes. To avoid such situations, we ask you to contact us before purchasing a set of tubes to verify the set of tubes you need. Also, situations where the tubes do not fit your amplifier, but correspond to the tube models indicated in the description, cannot be regarded as “Product does not correspond to the description.” Description: Complete Set of tubes for upgrade for stock Chinese 6P1 6N2 amplifiers.

Testing process: All tubes sold by us are tested on a high-quality Soviet device L3-3. In our laboratory there are three L3-3 of the latest modifications and several ancient L1-3, each of which has its own modifications to make the selection of tubes as accurate and high-quality as possible. If applicable, we also test the tubes for noiselessness on a special amplifier bench assembled for such tests. When selecting tubes, we try to choose tubes that are as similar as possible in terms of their parameters. The matched pairs\quads shown in the photo are one such example. The meanings themselves vary from pair to pair. If you want to have a pair with certain values or know them before buying – please write to us. Our standards: 1. All tubes we sell have never been used and have been stored in warehouses. We carry out a careful selection and testing of all tubes on a variety of parameters. 2. We package all items securely to prevent any damage during transit. 3. If you have special requests for tubes, we are always open to dialogue.

We are constantly in touch and try to help everyone who decides to join the world of hot tubes! The main thing is that it is beautiful and cool! We are grateful to our colleagues from China, who, with their prices that are impossible for a Western manufacturer (American or European), made tube amplifiers affordable for a non-rich client! ( expanded the market at times) We are rediscovering for ourselves some types of tubes, which (it turns out) can be very different in sound from the year of manufacture, batch, plant, country! Constant monitoring of the forums will help us, as well as many years of experience in testing tubes and making professional tube amplifiers! Practically, all NOS tubes (our subjective opinion) have never been made for HIFI. Especially Soviet ones! That is why you have to look and try! Less hearing from others, more listening to yourself – We are all different! Considering that many types had a military purpose and are therefore very reliable! The entire modern remake is an order of magnitude worse in this parameter. Special orders: If you did not find the adapter or saver you need in our store. You can request a custom production. We can produce an adapter or a saver according to your request, taking into account your wishes for materials and components.
