QSX Mark III "normal" phono amp


New nice pcb's of my "normal" phono amp will arrive in a week or two. Those who don't laugh at me please go on reading. The other ones, stop reading at once. It's bad for your health!;)

The amp is a blueprint of the application note from LT. Those of you who really want to make this amp exactly as the original can do that. In order to please myself I have made a few enhancements.

Any (almost) opamp will fit including offset adjustment and DC-servo.

The buffer is the LT1010 but for conveinience (wrong spelling?) I have made room for a convential buffer with transistors.

On the board there are also regulators and rectifiers so 2 x 18-24 VAC/DC is all you need.

If anybody wants to build this amp before I have debugged the pcb's feel free to do so.


I have also a bunch of LT1028 (better DC specs than LT1115) for sale.
It's a way of getting attention and I succeed. I myself gets very happy when I see others showing their work how "ugly" they may be. I know the feeling in doing something and make it working.

I had my thrill when I listened to my monster phono amp for the first time. I will soon have more thrills, I hope. I'm also honoured that Mr. "The one and only" have some respect for me despite the complexity in what I do.
methinks this is not a hard case of spamming. maybe a border case. And what he does at AA, i really do not have time and nerves to survey that, besides it is none of my business.

What happens concerning the other diyAudio email i have in my inbox waiting, i decide that tomorrow when i got some sleep and my eyes are no longer bloodshed, ok?

Oh, and keeping the moderator busy also is an offense.

ok :sigh: as i have been asked, could you please avoid advertising for your products except in the the trading post board.
