Hi, I eventually plucked up enough courage to finish my Corda Build ( free PCB's that were given away ) and connect to 240volt. No fuses went, but LED burnt out and all I get through the headphones is a constant hum which does not change when using volume control. I have cleaned the...

I'm looking to putting together a sound system, am I better to spend £150 on a NAD 521bee, or perhaps a cheaper DVD player and build or buy an external DAC. something along the lines of a Monica 2, Zhaolua 2.5 or Audiodiylabs DAC101 thanks.

Hi, I need a new power supply for my PPA v1.1, would a a.c. adapter from a fax machine be OK? the specs are: Input 240v - 50-60Hz 0.5A Output 24v - 1.5A Thanks.

Does anyone more skilled fancy having a check of my frontpanel design? I have by more good luck and eye designed this, its basically 2 x Hammond 1455N1601 enclosures side by side one for the PPA one for Steps. Please let me have any comments or let me know of any mistakes, I'm sure there...

Hi, I'm casing up my PPA in a Hammond enclosure 1455N1601 and see some of the builds use nice Stardrive/Allenhead type fittings to hold the end panels on. Can anyone tell what size they are, and also does the case have to be tapped, or will they cut there own thread in the aluminum? Thanks.

I cant get a 2.0k resistor locally, nearest 1.8k & 2.2k. I want to get 24v out of my steps, so if my calculations are correct I'm better to use R3 100ohm R4 1.8kohm which should = 23.75volt With Vset adjustment I shoud be able to get my 24 Volt Please tell me if I'm wrong.

Hi, Has anyone done a parts list for the Steps v1.2 from a UK supplier? The parts I'm finding hard to locate are Choke & Transformer. Any further help from builders would be greatly received, first time into 240volt builds

I'm going to stack 2 buffers on the right/left channels and just leave the ground at 1. I just want to check that I have this right, 100ohm right/left channel and leave at 200ohm for ground channel. thanks.

Hi, have just received my Pimeta PCB and new alps pot with switch. I just want to check resister value, schematic says 1m, but I think it should be 10 x pot value (10k) so that is 100k, can anyone who has built with the new pot confirm what they used. Thanks.

Hi, I have been given a LC-iCute-K1000 PCB, but cant find any information about it in english, has anyone here built one, and if so can they supply me with a parts list and any further information. Thanks

Trying to put my order together from Mouser, can anyone recommend a capacitor for c7 the bass boost,or is it worth fitting. Also what are s2l and s2r on the board layout, are they for the boost switch? many thanks.

Are Tantalum bead capacitors polarity sensitive? I'm building a clone amp, the parts list said Tantalum capacitors. when I received them they a have + marking for 1 leg., but the schematic's that I can find never show any of the capacitors with a + - orientation.

I have a Protel file I want to open, but I dont have Protel, is ther any other programe that can open it?

I have built a cmoy with a gain of 11 as standard. I get a slight amount of hiss at approx 2/3 and higher volume with nothing connected, and the hiss is slightly louder with mp3 player connected on pause, still only top third of volume, which is to loud to listen to anyway. Is this ok or should...

Can anyone recommend a suitable part no: for RS in the UK for a suitable C1 capacitor for Mint Board. my local electronics shop only has 1uf & 0.22uf in 250volt and the lead spacing is way out. Thanks Alan.

Can I just use a 1n400x diode for the mint power section, and leave out diodes for the amplification section? I have used the forum to search for these answers, but are just getting more confused - and I can't locate 1n5822 / 1n5298 in the U.K. also if I leave out the diodes in the...

I am looking for some prontoboard as used in tangents mini-cmoy pocket amp build, anyone seen it for sale in the UK? i am at a loss were to get it from. Alan

Hi all, just thought I would let you all look at my first attempt at making a cmoy amp, worked first time too! Had great difficulty finding the protoboard that Tangent used, or was not going to pay the price the local electronics store wanted, so I decided to make a pcb using transfer etch...
