I have been adding in a couple of chokes and WIMA DC Link capacitors to the power supply. So, now I have an L1 C1 L2 C2 C3 power supply. Additionally, I removed the hum potentiometer which was good and bad, as it added some hum but also made the tonal balance better and more transparent. Since I have a small bit of hum, I am going to try Rod Coleman filament regulators. Once the Coleman regulators go in, then I may go with an Ultrapath schematic for filament supply. This will remove a large capacitor from the audio signal.
My system sounds better than ever. Super transparent without any glare or harshness. I also had to rewire the power transformer and used 12 gauge silver coated copper wire. It sounds better than the cheapie wire that came from the factory.
I am looking to replace the power transformer, but have yet to find any specific brand / model that looks like a sonic improvement. Any ideas on this?
