Cct. brd. is complete with a 10,000uf cap (snubbed) across the 27V PS rail. A 1ohm resistor sits between the PS and the big cap (a la Pass). Also each channel has two 220uf lows ESR caps (also snunned) at either end of the V+ rail after the 10R de-coupling resistors. WireWrap wire (WWW) is used as hook-up wire for signal and PS. Silver solder used thoughout and gold RCAs on the back. I used 2SK170 jFETs BL (50 cents each, why not)?
Did I mention it is all housed in a gold embossed chocolate box. Those who know me are probably not suprised. Also the box has a clear plastic cover under the gold embossed top. The top and bottom of the box are lined with bitumanised Al foil. Currently the unit is powered by three 9V lithium batteries. 1mm pure silver wire hooks all the earths up and multiple strips are ganged together for the V+ and neg (earth) rails. The input wires and the PS wires have tiny ferrite beads on both the hot wire and ground. The input hook-up wires are not sheiled (I don't like the stuff) but the WWW is heavily twisted with the earth wire.
How does it sound? By far the very, very best phono preamp I have ever, ever made. All my other preamps, both tube and OPAMP based have a very slight background hiss and thermal noise. This has absolutely no back ground noise or sound of its own. It is dead, dead quite. The brown polies are doing a fabulous job of letting the music through and I feel, adding nothing.
I have not heard my vinyl ever sound this good. It feels (sounds) lite and airy. Beautifully transparent and detailed with a very rich extended bass. Bass is weighty and detailed. This, for me, is a huge step-up in my vinyl appreciation. I'm rapped!!
Just a note. The cct. called for a .034uf cap. The way boozhound does it is with a .033 and a .001 cap in parrallel. I could not get these in the high voltage polypropelene caps I used. So I used two .068uf caps in series. This give the required .034uf.
For god sake if you play vinyl make one now. All you need is a few caps, Rs and chocolate box. Seriously good.
