Hi there,

I have made a few pedals, over the last few weeks, and have now decided I want a long term project, as well as the pedal buildings. Can you suggest any long term projects that I could do, although I not too keen on building an amplifier (as I've just bought a new one!)

Thanks in advance

What about some studio recording equipment? Like clone of a UREI 1176 FET compressor or the compressor from an SSL mixing desk or the EQ section from a Calrec mixing desk?

click on DIY projects and theres a whole new world there.

BTW
I just ordered a PCB for an 1176

Taz - what's your estimated cost for building that 1176 (assuming you have all the tools, etc)? Where are you getting the PCB done and how $? I'm thinking about building one.

I'd love to see a parts order spreadsheet if you've got one, some on that site weren't very current.

Hi.  A while back I built a high power SS amp with a beaut pre-amp that had an equaliser, a couple of distortion effects, an echo effect (Tonepad's rebote) and an LED power level indicator.

The limiting factor power-wise is usually the power supply.  I used 1 300W transformer, but looking back I should have used 2 (they're only US$50 each) and built a 600W amp.  I know you've just bought an amp, but other people might be wondering about a cool project.

PS Although this is a SS amp, it compares fairly favourably with my 65W tube amp.  It just needs a tube-like overdrive (e.g. CD4049-based) to make it sound graceful at high output levels.

Try designing something yourself, put it together on a breadboard, tweak it, start over, do as you please. It's a great way to A) kill time and B)have some fun, with something cool hopefully coming out at the end. And then you can post back and brag to all of us what a cool pedal you designed

kdawg:
My estimated cost is around 350 dollars. The partslist I'm still working on but if you mail me on

taz@bredband.net

then I'll send you it as soon as I've ordered my stuff (I'm still trying to source the cheapest place for components) and a couple of the components are difficult (although not impossible to) to source. The most expensive part is the VU meter but I'm going to use a Behringer meter (nice that behringer is good for something).

If you go to the Tech tips forum at www.recording.org you will find a forum (not dissimilar to this one but for studio effects) There are laods of people who have built 1176's so there loads of info.

The PCB: On the gyraf site are PCB files ín a format called gerber you can send this files to any PCB manufacterer that deals with prototype boards and smalll runs and they can make a PCB from them. I chose a company called Olimex at

www.olimex.com

and got one  professional silk screened and tinned PCB for 26 dollars including delivery to Sweden - unbelievable. the guy at gyraf allows people to produce PCB's from his files as long as "fair use" is followed.

kdawg :
just remeembered the meter was not the only expensive part but the transformers are as well. The Output tranny is anintegral part of the the circuit and there is a tranformer replacement availbale form Lundahl tranformers in Sweden and it costs about 50 dollars this one is essential. There is also an option on the PCB for an input transformer or an opamp input (the original does not have an input tranny).

The 350 dollars estimated cost includes the input tranny but not the input.
