With the supply 90 VDC, 25K Ohm Bleed Resistor and 230uF(summary) output capacitor u will need wait about 6 second to connect headphones without poping noise. If after that u will hear single crack/popup noise then lower the valu of bleed resistor.
Like you said, many parts has been changed it is now like a new amp and needing burn in, to get it best!
I haven't found 22K in my stach, could I use 25K without detrimental effect? It is very interesting thanks for the knowledge WALL-E!
I received the BC 1000µF 200V and installed them. I added 30µF MKP caps to the output coupling, and I removed all the bypass caps too. I think it must be the brand new caps but I find the sound lacking bass. The sound is relax though but the bass quality is not there. I will let the amp burn couple dozen of hours and see if it improves.
Overall I prefer the sound before this mod, highs were more calm, and bass were deeper stronger. i strongly suspect the caps needing burn in.
