    works fine. Check the transformer, must be 12 v AC. One of the valves seems to be used, :(

    Nice little valve preamp. Easy to construct, works at first attempt. After a few mods for more gain and converted into a 4 channel stereo mixer (very easy), I am very satisfied with the results. Finally I achieved the warm an calid sound of electronic tubes into my HIFI sound system!! 100% satisfaction, highly recommended.

    Aqui está um Kit muito bem pensado e de construção acessível. Faz falta um guia para ajudar na hora de se montar este Kit, mas o grau de dificuldade também não é nada de impeditivo. Com a caixa fica um conjunto muito atraente, e com uma qualidade sonora .... razoável. Fiquei satisfeito!

    Prodotto che funziona bene, fascia bassa economica ma che si distingue comunque. Attenzione la cover di plastica non viene fornita, bisogna comprarla a parte!

    conforme pedido numero 59029192 (6j1 preamplificador tubo estereo ca12v diy kit) observa-se que na lista de componentes consta o box ou case com os parafusos mas (NAO VEIO O BOX OU) ( case) ou caixa de acrilico para o amplificador 6j1 estereo) sendo que consta na lista...... e nos comentarios de outros compradores esta nas fotos dos mesmos com a caixa box mostrando que contem a caixa... observa-se que eu ja comprei varios produtos do BANGOOD e nunca tive problemas nenhum em faltar nada e nem produto

    Like the blue leds that lit the tubes, looks really good. No documentation supplied but PCB has all information for placement on the silkscreen which is sufficient to place the components correctly. Although a little bit of electronics knowledge is beneficial, at least to know the color codes of the resistors and that some components(diodes, electrolyts, transistors) have to be placed with the correct polarity. The sound is good, nearly no distortion.
