Who has built their own?

Who here has built their own amp from their own design? I'm talking about from scratch not premade boards etc. Beside Mr Pass and Mr Curl, of course, has the true DIY spirit bitten anyone?

I´ve built several, some of them even works!

Yes, there is nothing new under the sun.
I mean you took the time and effort to take a blank sheet of paper and figure out a circuit that would do what you wanted it to do and actually build it.

Maybe better question will be : who have any original mechanical / electrical construction, which is not crazy and have for it any logical explanation ?

I have built my own designs.

Upupa Epops · 19th June 2004, 09:51 PM

Which circuit do you mean ?

markp!

I haven't built anything designed by others since 1990. It was a TDA2003 amplifier.

This is my latest product, (finished yesterday) a 2kW SMPS:

It's not final, it's only prototype. Even the inductors are made by myself. (PCB is only designed by me, but made by professionals.)

I have designed and built a few amps and pre-amps for my personal use. But, as anybody, I do not re-invent the wheel. I started my inspiration from schematics from what I have already seen. In fact, I have never been able to construct an amp based on a "public" schematics without modifying it a lot. I see (or maybe imagine...) always "flaws" in the design from either my experience or knowledge (at the time). What I like about analog audio design is that it is a bit like "art" sometimes and the goal (perfect amp) is probably unachievable (since the amp interfaces with imperfect things too: source signal and load). Lately, I decided the approach to use a "public" design and try to modify it (a lot, in fact) to experiment on the sound result.

Oops! I realised that the question was about amplifiers! Some of them are shown here: http://www.hszk.bme.hu/~sp215/elektro/index2.htm
