6J1 Valve Pre-amp Tube PreAmplifier Board On Musical Fidelity X10-D Circuit Bile Preamplifier Buffer Board
Product Description
It is made by patch + plug-in technology, and the filament and the amplifying part of the tube are separated and independently powered, and the noise is further reduced. (This power supply is very important, and it is related to the sound quality. One AC 12v is changed to two independent AC 12vs. It seems to be a bit troublesome, but remember: if you want a fever, don't be afraid of trouble) Of course, if the requirements are not high, a single 12v transformer can be used in parallel with the two power input terminals. Note: The board uses two independent winding 12v transformers (not the dual 12v, three-wire type) power supply, and independent power supply, sharing with other equipment may cause noise
