    Naim 523 S/K boards - modification ?

    So on the S variant the input cap/resistor combination is 6n8/470R. Simply change those two to 1n/560R - job done. For a significant upgrade use a 0.1% Naked Z-foil resistor. And while you are in there replace the tantalum caps too - same values just a good reliable brand such as Kemet.

    Replacing Naim 32.5 / 72 balance pot with fixed resistors

    Sorry I'm a bit late on this one (not around here as much as I used to be). But I have seen (and heard) rooms that need a balance pot to correct for some acoustical imbalances. If yours in one then removing the balance pot may not be your best solution. In which case at 2 O'Clock the balance pot...

    NAP150 Options?

    As it happens I only recently acquired a NAP 150/NAC 112 pair - listed as non working and in mint condition with original cartons...a bargain price too. The only faults I could find on either piece were a leaking reservoir cap and a dead LM317. Once both were replaced normal operation was...

    A friend of mine has blown the tweeters in a pair of Allaes...we are looking for replacements but can find no info on the web as to what they are.
