The Lampizator is an SRPP circuit, but with certain Russian tubes -6H6P. (6N6Pi) I have a set, but have not used them yet!

Hi,

i use the Lampizator Stage from Lukasz in my 4*TDA1541A DAC with outstanding results.

You could read it in THIS thread.

Best,
Oliver

I have been contemplating what kind of caps I should use to replace the 14 220nF surface mount caps around the TDA1541A with, got any good suggestions? I hear that Nichicon Muse are good in the power supply, I have 2 Gold tune 10,000uF 71V caps salvaged from a Sony amp and 2 330uF 50V BG caps that I purchased a couple of years ago.

In my CD player (SONY CDP-XB930) there is a digital output, so if I wanted to try this, I think it would be best to leave the CD player as it is and build an external DAC unit with tube buffers. Right?

Well there is a lot of confusion on how this tube is called. As it's a Russian tube, it's marked in Cryllic. So to those of us who mostly read the latin alphabet, it looks like 6H6n
But that would actually translate as 6N6P in latin script. The last letter looks like an odd letter "n" in the latin alphabet, but it is P (Pi) in Cryllic. As in Greek. Π

I hope that makes sense!

Thanks all.

I thought this might have been a way to improve the sound of computer CDrom drives to use them as reasonable audio CD Drives.

I see now it is about improving audiophile CD drive systems.

Hi again,

I have check with my scope on my player.
The left signal is taken from dac output and the right signal is taken from the rca after amplified by tube.

It look like the signal clipped just after the dac. Any idea how to fix it?

My cd player dac is TDA1549T.

I see your point, I actually have a bunch of old computer CDrom drives stashed away waiting to be Lampized or have their cheap output opa-amps removed for experimentation, but that may be for a more spacific thread yet to be created....
