Mundorf M-Tube in Tube Amplifier Power Supply

Hi,

I did  step 2 - removed Nichicon capacitors 2x100uF and 2x20 Ohm resistors (one resistor per channel) between choke and ClarityCap (output B+).
I don't like results. Bass become lightweight. As result too light tonal balance and
less information from lower mid-range to deep bass, less body of instrument.
Probably sound without  Nichicons a little more clean and airily, but the difference in very small.
Probably 100uF is not enough for 2x 300B tubes in class A with total idle current 130mA?  Before adding ClarityCaps output stage B+ capacitance was 200uF and when Nichicons and ClarityCaps were used together - 300uF .    
So, I going to return  Nichicon capacitors 2x100uF and 2x20 Ohm resistors back.

I'm not disappointed at all. It was a good experience for me.

Alex.

I just added a scheme of power supply update and a general  scheme of my amplifier to "my system" page.

Nice work! I am sure your comments are spot on regarding your particular amps design and capacitance needs.  Always best to try and learn! Great job!

Hi @grannyring ,

I installed Mundorf 30uF Mtube capacitors in driver and input tubes B+ instead of old
100uF Nichicons.
The first impression was good - warm tonality, fast bass and micro-dynamics.
But now I recognize that my amp sounds too forward and too much emphasis mid-range and vocals. The high frequencies extension is not as god as in was with Nichicons too.
Does is a typical Mundorf Mtube sound or these capacitors need more break-in time?

Alex....since you are using a 4 poles type electrolytic caps.   The Clarity tc series are ok.  I strongly recommend the Jensen 4 poles.  In the 4 poles series ( Mundorf, Clarity, F&t, BHC, Sprague) the Jensen 4 poles IMHO is the best  electrolytic caps.  Better bass responds, more dynamic, transient, especially the sound stage, imaging will lock better.  Remember not all 4 poles are equal; i only recommend the 500volt +.   Happy Listening!
