The CCS amplifikation is quite high and the bandwith also. I have not calculated on the poles so I don´t know the phase margin. When i got time I want to do a spice simulation. Anyway the decoupling worked well. Reagarding the 150H choke. A choke supply will generate an opposite current and...

Fixed! Thanks Jim L11! I put a decoupling cap on the positive terminal of 10M90s and made the wires shorter. Maybe adding a 150H Hammond choke in series after each CCS could give both a larger "swing" and better s/n in the higher frequencies? Maybe 2*150H getting 300H and get rid of the CCS is...

Hi! I had an old Srm-T1 lying around. It sounded ok on my Stax 407 Pro headphones but I thought that maybe some recapping and adjustments was needed. Originally there was 4*100uF Caps in the power supply. I changed to 4*680uF and it was a nice upgrade. Then I found that changing the anode...
