WK-WK Preamplifier - common cathode ECC82 preamplifier

WK-WK Preamplifier is the simplest vacuum tube preamplifier that can be made with only a few components. Output signal is reversed in phase in relation to input. The board is absolutely hum free, just make sure all grounding is done nice and tidy. As there is no NFB the gain of the preamplifier and THD may vary a bit but this is not so important in this case. Most important is the fact if we like ''tube'' sound or not, I must say I like it a lot.
