They will make any value resistor that you like, and send them anywhere you live. The resistors I got were just under $7 each.
BTW, the next version of the board looks a bit different, though the filter section is the same.
How many did you order? It's something i'd like to do. Any additional info would be much appreciated ;-)

After dragging the kids to the electronics shop on the other side of town today to get the regs to do my driver ICs, I've just finished taking the player to bits and discovered that I've managed to buy 7808s instead of 7908s :-/

I worked on my 5v supply instead. I've got the 4 regs going on the DAC supply now, and have nearly finished building 8 more for use elsewhere. It's sounding great! :-)

I no longer have any boards for sale, but Ray has newly designed DOS boards for sale.

Hi, I was referring to the resistors rather than the board ( I have a couple of Rays boards). Did you just mail them and was there a minimum order quantity etc? Thanks ;-)

I've got three of Martin's LM317 regs driving the decoder chip now, adding to the four on the DAC. I cut trace by the decoder so I could add an extra capacitor for digital supply 1. All analogue supplies are decoupled by Black Gate FK and all digital by Black Gate NX.

This went very smoothly, except the disc keeps spinning slowly after the player has stopped now for some reason... I've invented perpetual motion! It's amazing what these players can do :-b

Thanks! I got all my Black Gates from Michael Percy in the States, except the big FK smoothers in my amp which I got from a private Audiogon sale.

I've been interested in modding my hi-fi for years, initially after following Brent's PM66KI mods. It was the drying up of BG supply that spurred me into action, so I got all I needed just in time.
