If you don’t mind i like to ask you another question (actually 2 questions or 1question and 1 opinion).
I’m selecting the components which will be used in the amplification sections (done with the PSU stuff for now).
Took your advice on using Jantzen cross-cap for the 22µF caps in the tube supply sections and while I was out to buy them picked up cross-caps for all other values I needed.
It turns out that that no such thing exists as a cross-cap with 10nF or 27nF so had to revise my initial plan for the RIAA filter.
First thing that comes to mind when thinking about caps for audio equipment is WIMA.
If I’m not mistaken I also spotted some of the familiar red blocks on your photographs (not sure if this is in the RIAA filter).
But I also dug a little deeper while I was on a world wide web search.
Now the question.
I can get my hands on MKP capacitors with a tolerance of 1%.
WIMA at best offers 5% or even higher.
Considering these caps are not in the signal path what would be preferable to go for a well-known (will sound good) brand or the strict tolerances of 1% (these 1% by the way are Kemet capacitors).
Second thing are the step-up transformers.
I ruled out the use of Lundahl transformers as they are way too complicated for me with 20 different configuration possibilities.
I’m now looking at Softone instead an alternative could be silk audio or Jensen.

If you are going to use LOMC with it (I do) then you will need to use step up transformers (most major companies do as it is like free gain without noise). There are a few that I really like. First is Silk Audio's SAC1 (about $200 a pair and available in a nice case assembled for about $100 more - a bargain), then comes Softone PLC-1, after that either Lundahl 1678 ot 9226.
But in Audioxpress you wrote “My present one of choice is the Softone”
