Thank you - I wish it were all true, but I think you overdo it a bit.

Regarding my own version of a power amp, I am by now criminally late with it by some 4 months or so, in comparison with my own objectives. Some objective, some subjective reasons. However, this is a non-profit project, I am basically making it to please myself and anyone else who might be interested.

At the same time, I am trying to drive a point home - about 99.99% (literally 1 in 10.000) projects you can find on the Internet are simply schematics of the amp, and that's it. No excess DC protection, no thermal protection, no overvoltrage, no overcurrent protection, no signal status indication. Yet, all of these are VERY MUCH present in amps right up to the Krell level. Why is the DIY guy denied these things? When it's more likely he'll have these problems more than a factory unit, they just make the protection aggressive and sleep tight.

A real project, as I see it, should offer all these facilities and let the user decide whether he is going to use them or not. If not, just leave the board unpopulated but be aware that you do so at your own risk.

A real project should also include all of the PC board artwork, so anyone can do it, anywhere, and people like you, who live 40 km away, should be able to buy them from a reliable source, if they so choose. Lastly, you should have a complete adjustment and chekcup procedure outlined for you.

Then, and in my view only then, you have a complete project.

But, obviously, this is quite a bit of work, and since this is fun not work, it heavily depends on my free time - which I have a lack of.

But I will get it done, I think I am by now over the 3/4 work done line.

And, I need to say this, a very fair bit of it is a result of the discussions led here, so most of the contributors on this forum have pitched in, for which I am truly grateful.

I am especially indebted to Mr T (Thorsten Loesch, now off this forum, a friend of 11 years or so) and Nige(el Pearson), just off to Malta, the lucky sod. Watch out for the crabs, Nige.

That only means you have been fortunate enough to hear the scream of a healthy engine at 8,000 rpm or so. It's a sound you hear once and never forget.

By "healthy", I mean honestly tuned, angine brought up to factory tolerances or better, standard parts exchanged for really good new parts, almost by default of better quality than the original parts.

With amps, it's the other way around. You certainly don't want them screaming at you, healthy or not, you want them to give you that priceless feeling of unlimited power, as if you can never overload them.

I always wanted to tune the Audi engine of my old VW...

With my last amp, I experienced it, until I gave it to my client.

Yessir, he sure has been. But, that's old hat, he's been busy ever since I met him, the only worthwhile question being - doing what?

As for not being here, I believe the reason is not that he's too busy, the reason is that he has been banned far too many times for speaking his mind and having the misfortune of being a little too different for the taste of the powers that be.

I deduce this from personal experience - I don't write to him every day, but every time I did send him a message, I got my answer in good time. Without fail. On occasion, not at all gentle, sometimes even stern, but always helping out. And I've always come for the better out of it, that's a fact.

I found him hilarious with his backhanded responses, his snatch(the movie) level sarcasm was top notch ..

He's over at another place:
DIYHiFi.org • Index page

And if you like 'backhanded responses', he made a dooozie in here!
DIYHiFi.org • View topic - Any of you guys look at NWAvGuy's Blog or his ODAC?

And they say Germans don't have a sense of humor ... just shows how flippant such silly generalizations are.

But you are right, T. doesn't often mince words and always either speaks his mind or says nothing, very digital behavior, 0 or 1/1. Kinda strange from a dedicated tube man.

But, such is life, each and every day, there are less and less of us perfect ones around.

Can anyone decode his nicks in that wild post and the actual ones in here? From the description about the attacks on JC and the mention of the MC pre-pre I managed to figure out who one of them was, and made another likely match based on the association with chemistry, but after that I couldn't get further.

Not that it matters that much.
