im afraid they do not have any outlets that i am aware of... but do not worry about ordering from them - they are very good, all of my oders have been recived the next day and delivery is free if you spend over £30.

Nuuk - i am afraid they only sell some high quality resistors (Meggitt Holsworthy) no good capacitors but www.audiocom-uk.com sell some and the prices are ok - im afraid i have not bought from them yet though

Thanks Fezz but there are some big questions about dealing with Audiocom.

I'm still awaiting delivery of some caps that I ordered last Thursday and was supposed to be despatched the same day.

They don't reply to phone or email messages and I have since heard from somebody who ordered stuff, paid for it by credit card but never recieved it. That's why I was hoping to find an alternative supplier.

Post has just arrived and still no capacitors!

This is a real shame, as Audionote have now stopped selling components as well

I was wondering just how many of us there are in the UK buying these sort of components. Maybe, we could all get together and persuade RS or Farnell to keep a range of Black Gates, Silmics etc. Farnell do OSCON SG's so I can't see why they wouldn't do some more 'exotics' if enough of us asked them to.

Ideally though, a smaller supplier with no minimum order charge would be better. Cricklewood Electronics is one that comes to mind.

It shouldn't be too difficult to canvas enough people through the various hi-fi forums, newslists etc.

The ESP projects are well documented. If this is your first time, I do recommend ESP project other than others. And using bipolars! You seemed to have selected the best ESP projects
But I recommend you to build the amp (may be with the pre-amp) first, and forget about the crossover.

If cost is your big concern, I think I must tell you that DIY world is filled with maniacs who do not care with money they spend. Hobby is hobby. If youíre looking for a cheap way of making a good sound system, DIY is usually a wrong way. Only experienced DIYers are capable of getting the most out of the least. But bipolar is the right option.

If you are going to build the PCB by yourself (looks as if youíre going to be one of the maniacs), I donít know what to say. Just expect you will get serious hum.

What Causes the hum you speak off, I thought that a circuit was circuit and that the interference between the magnectic feilds was very small, this being the only thing that I know of the could cause this type of thing. or am I underestimateing how much Disstortion this will cause

Is there any way to work out how much a design is going to hum.

The software I am using uses skematics that you design on "Crocodile clips" it then creates a design whitch is etched by a computer controled etching machine not an echent tank as I first said, this is because the place were I am doing the ecting has just had everything upgraded.

Cost isn't the main thing its more i want to know how much it would cost so i can comparte it with other settups i have seen

Hello,

I built exactly what you described. I put a P88 preamp in a 1U rack case along with a P05 power supply, a P06 phono preamp and a P81 active crossover. I built a P3A and put it in a separate 3U rack. I bought all my boards from Rod.

I am a rank amateur compared to many who frequent this board, and this was my first attempt at amplifier building. But, I think you are correct about it being a great sound system! I haven't heard many high-end systems, so I may not be one to judge, but I am constantly amazed at how good it sounds.

I'm in the US, so I got my passives and misc components from DigiKey and Mouser. I got the best quality I could find at those places (1% metal foil resistors, best quality Panasonic caps, etc). The smaller transistors I got from Newark, the output transistors I got as samples from OnSemi (MJL3281A/1302A). The heatsink came from e-bay, Transformer is a Plitron 400VA 30-0-30, cases came from Par-Metal (great value). Miscellaneous parts (Alps volume control, 5-way speaker posts, gold-plated RCA's, press-on lettering, etc., etc.) were obtained from various web sites.

I also built Rod's DC protection unit (P33), the fan contoller, and the clipping indicator. I built a DC trap for the mains that was discussed in a thread here a while ago.

All-in total cost for the whole enchilada, preamp and amp, was about US$1100. I sent many emails to Rod, and asked a lot of questions, read many posts on this board. Many of my miseries were self-inflicted, and I learned a lot about what NOT to do.

I originally put the active crossover in the preamp to split the signal at 60 Hz between the P3A and my sub. The idea was to take the <60hz signal off the P3A. However, I find I like the sound much beter if I send the whole signal to the P3A, so I am not actually using the crossover at this point.

If you want to see pictures:

Hope this gives you some help.

Hi!

For high end parts you can also buy at partsconnexion. (www.partsconnexion.com).

They also deliver abroad (from Canada), with no heavy postage fees, and carry some of the most exclusive DIY parts that are available (BackGate, Jensen, Rikken etc.).

And tax (if it should apply) to EU for electronical parts is somewhat around 1.7%. So if you can't find a local source (for high quality components), try them.

Bye,

Arndt

That depends, some people I know drives a Austin Minor when they learn to drive, some people I know drives a brand new BMW with an L plate on... so which group do you belong?
