"Designing tube preamplifier" article

And
Alex if I can say,
The syntax and other errors
could be corrected,
BUT
The bad attitude, and basic psyhology of personality
I am afraid, could not be corrected, in same way

Yes, Belgrade, in Serbia is the place I am living
just like anybody else living somewhere,
I do not see what is to do with, about the topic on this
public forum...

As we dutchies say 'Zachte heelmeesters maken stinkende wonden' so:

Really sorry but this whole article or whatever one calls it is crap.

The assumptions you make, the way you hand it out as the gospel and
lace them with either wrong or pointless topology's. Establishing your
own standards for levels and the 'electromagnetic garbage from the ether'
joke....

'All of the heat transformer units should be placed under the chasses' ? Yeah sure

'overloading input of the amplifier, supplying amplifier input with a opposite phase,
coloring the signal with a cables reactive load and shorting the bandwidth from the
booth sides via wrong potentiometer' Say what?


We should leave the tube filaments to “rest”, go read tubecad and the likes
and I guess you should go back to drawing, painting and media

Thank you Westerp for taking the time to read (I just cannot read such texts and live with it).

This is basically what I smelled from the first few lines, but did not want to be the first to point out.

Yes only to those whose feet are not touching the ground (as we Serbs say "koji su nabeđeni"). Sorry, but that's the way it is. And that is why it never got published.

Guys, there's helpful criticism and there's unnecessarily personal sniping and snark. I think this has crossed into the latter. Please keep criticisms to the technical details.

I haven't had the time to fully read through it just yet, but I will. I did glace through it though and it seemed like it would be worth my read, although it is a tad long. The one thing I saw I was wondering about was picture 21 (I think) where you show a 6SN7 coupled to a 801. Is the elaborate hum cancellation on the 6SN7 heater really necessary? I mean I have never had a problem with AC heater hum on indirectly heated tubes with just a small value cap across them (sometimes) and a very small dropping resistor. Like I said though, I will give it a deeper read, thanks for posting.

Cheers

I've removed two posts. Any further personal stuff, it's Sin Bin time.

Saved the article. Thanx.
