I know this is a bit off topic but could anyone help me out a bit. I just got a used Minimax dac and when i use the tube output it has some hum/noise in the background. It only goes away then using SS output. The hum is more pronounce when the volume dial is from 0-75. From 76-100 the hum is till there but less. I tried with a Brimar tube and same, Pangea power cord still hum. Thanks in advance.
Success Rolling Opamps in EE Minimax DAC
I'll try to reign in my nearly unbridled enthusiasm for a recent uber-economical tweak, rolling Opamps in the Eastern Electric Minimax DAC.
On encouragement of Chris and Melissa Owens from Clarity Cable I swapped them out (note; this voids the warranty!), with resounding success. A more powerful upgrade per dollar in decades of messing with systems and tweaks does not come to mind.
