Date 1970s. Excellent quality. Tubes are new, taken out from wholesale factory box. Main technical characteristics on 5Z4M: Heating voltage …… 5 – 0.5 V Filament current …… 2 – 0.2 A Anode voltage nominal (constant) …… 50 V Anode current nominal (for each diode) …… not less than 300 mA Anode current limit (average value) …… 140 mA Anode current limit (amplitude value) …… 415 mA The anode current at the moment of switching on the limit (amplitude value) …… 1.4 A Rectified current (for each diode) …… not less than 133 mA Voltage of the secondary winding of the transformer …… 2×400 V Filter capacity …… 4 uF Resistance in the anode circuit …… 4.7 kΩ 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.

About us: Qualitatively tested and selected tubes at a reasonable price! Savers, adapters and converters for customers who decide to play pipe rolling or extend the life of their tube amp! 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.
