I'd love to report this is a great kit - and the NE5535 is a fairly neat chip so it's a good choice and the use of single-rail biasing is convenient. Things go downhill from there though. I've come to trust designers and when I first built one of these I was disappointed by the performance; particularly at the low end. Turns out this amp - simply down to poor component choice - rolls off at around 160Hz - making it pretty useless for music. Simply increase the 1K resistors to 10K (dropping the gain to x10) and a more respectable 16Hz rolloff is achieved; together with a more respectable 10K input impedance. Worse perhaps, is the choice of carbon film resistors - while these are easier to read than the metal film ones sold by Maplin (the blue body ones) they are noisy! Swap them for the stock Maplin metal film and presto, you have yourself the beginnings of a decent audio amp - for little extra cost. Six off D100K and two of D10K will do nicely! If you need more gain, just chain two together or increase the value of the feedback resistor - but beware that the NE5535 is prone to oscillations; and this board is no exception.
