If I put another nut can reach 4mm, the space between resistors is 6mm, is enough?

That's better Filipe. Looks good to me.

I've gone back to my 26 preamp with the two 156C in series and updated the power supply a bit. The hum is still there but not audible from my listening seat, just close up to the speaker. So that's proof to me that the 156C option is viable. I must say it sounds really nice with the FT-2 teflon output caps. I'm using a couple of ordinary commercial 12v DC supplies - probably switch mode I'd guess though I haven't got inside them. They sound much better than I'd expect!

Thanks Andy,

Try FT-3 in place of FT-2, huge difference: I have both.

Cheers, Felipe

Really? I couldn't hear any difference at all! Should I try again?
