ok, will try. thanks.

also there's a rather pronounced turn on "thump" - is that normal for the B1?

i know one should turn on the power am last ... but i forget sometimes.

I'm never hearing thump from my preamps

when powering up - first preamp , then amp

when powering down , first amp then preamp

so , that digit - operating power switch , need to be governed with some gray matter

understood.

on the hum issue: turns out i get an increased hum no matter which source or preamp (various phono pre amps, B1, iPad) i plug into my power amp. actually the hum increases as soon as i plug interconnects into the power amp. so i guess i have to move this issue to another thread....

In my build I'm using these for my 10uf caps at C101/C201: Mundorf - Inner Excellence

They fit the board and the price is ok. Do I need to fix them to the board with acetoxy free silicone or something similar to reduce/prevent stress on the leads? (The question is really independent of the brand, but I included the link to give dimensions.)

nice, they weren on my list also but i decided to go with jantzen caps. i th ink you'll be absolotely fine just soldering them to the board. they're really light and i shouldn't move around much.
