The thinner than natural mid tone is due to the generic resistors and caps. Try to get Shinkoh, and experiment with enough alternative 1000uF Rs bypass caps. I recommend Nichicon Muse NP bypassed with TRT teflon or FT-2. For output Auricap or Obbligato gold. But everything will play roles. After you end up it will be hard to beat. I know how it goes from generic to golden tuned in a revealing system. Brace yourself.

I will try bypassing with 1000uF Pana FM that I have now...the Rubycon ZL are always very clear but can sound a little thin.

I can get Kimawe or TKH resistor locally but maybe not all the values required. Can get Dale from Farnell/RS though if they are good enough.

Any recommended source for the other caps and Shinkoh resistor?

diyhifisupply has An Tants and Obbligato, but Shinkoh are better than ANs and you can look for them in http://www.hificollective.co.uk/ along small Silver Mica, Polystyrene, and other interesting stuff.

Salas, on filtering, I saw in a commercial phono stage that only has a bypass cap across the live and neutral of the transformer primary. Do you think it will work in my case?

Those things normally work to an extent, but can't say 100% if your fluorescent need local noise kill on switch. It can travel through many paths, better kill where it starts.

That will be a fast and maybe rewarding experiment. Let me know, bcs it passed my mind too when you first mentioned the ZL.

Quick check...could I put a 1.0uF X2 cap across the live and neutral of the transformer primary as a filter?
