'Blanket' replacing ceramic caps with silver mica, sensible?

[SimontY]

Hi again,

I 'popped the hood' on my player again last night, and was so tired I wrecked the solder pads for two components and accidentally smashed 2 ceramic caps.... oops!

But today I had another, less tired attempt at things, I -
- bypassed the 3 TCA0372 chips from 2 to ground at 16, I have no ceramics so used 22nF Wima
- added an earth post to the chassis
- bypassed a random 'lytic or two
- started shielding op-amps but ran out of time to finish
- nuded a large smoothing cap
- added some ground jumpers around the place, underneath
- replaced C106 with 35uF tantalum and mica - broke the pads so soldered it across the next points on the back
- added 0.0047uF x2 cap to 'bypass' 0.33uF x2

Only had a quick liste (it's late) and it works, yay! Seems to offer some more detail and texture, but only a quick listen - I could *easily* have imagined that... altho. I did hear a distinct crackling noise on an Eleneor McEvoy track, which I've never picked up before, so it's promising...

Thanks for the guidance folks, as ever!

Ah, I took a pic of the back, doesn't look like *this* stock
