The idea of writing 4k7 instead of 4.7k is that it doesn't turn into 47k after being photocopied umpteen times. Thus, we replace the decimal point with whichever multiplier we're using, 4M7 = 4.7M. 4R7 means 4.7 Ohms.

Thanks for that , ive now fit the resistors and its worked a treat ,i was wondering if you know what values to use when attenuating a cd input similar to russ andrews leads.I think its normally about 10 to 20 dbs of cut i would really appreciate your advice and im very greatful for your help so far .I would like to add the xindak pre amp was given to me by my best freinds wife he was killed in march in a motorbike accident so really am greatful for your help as i wouldnt have been able to use it without your advice cheers again

Glad to hear it works. 9k1 (series) and 1k (shunt) would give 20dB attenuation suitable for bringing a CD player down to 200mV.

Ive noticed that when i turn the volume up from 12 oclock[halfway] to full it hardly alters is this because the attenuation is to high .I have used 100k inline and 4k7 to earth in the plugs at the power amp end.Im guessing i need to alter the resistor to ground but to which value, sorry for the long delay but i dont usually play at this level of volume so ive only just noticed cheers again for your advice

Your 12 o'clock problem may be because the Xindak doesn't like your new low input impedance. Try scaling the values by a factor of ten, so that you use 91k and 10k.

Thanks for that ive tried those values and it works but its not enough i can only get to about 9 oclock [ the volume starts at about 7 oclock ].Could do with something in between the two values if thats possible cheers. ps can you get phono plugs that you can plug another plug into the back of and put the resistors inside it ,and any ideas were from thanks for all your advice
