    Received in 20 days, the order arrived well, the valves whole. In this module you should put 2 diodes that I will later weld, I already have the transformer suitable for this source, I already have the unit of the preamplifier and later do the final floor of valvulated power. I recommend this article for all reasons, excellent. Thank you Banggood

    Hello, I got one of the valves broken, the other is fine, how is it solved? Thanks

    This is a great little tube rectifier design, dont wory if you only have a two wire secondary from your transformer as you can just use the two terminals not connected to the twin diodes (which you need to add if you have a v-0-v CT secondary) the DC output is split between the two 6Z4 tubes so it gives you a very usable current for amplifiers, one of my included 6Z4 tubes had an intermitent problem but not a problem as I upgrade to longplate 6Z4s which are the same pinout but a bit longer still Chinese but very reasonbly priced like this rectifier which is an absolute bargain (my second purchase of this design).
