Default SP12 and PH12 Pre and Phono from Vacuum Tube Audio

I really miss my old tube pre amp (Audio Note M2 Signature) and wanted to get something to replace it. No way I can afford another one of those though.

So after a bit of reading around and a few fruitless web searches (mostly turning up Chinese junk) for suitable kits to build something I came across these:

Vacuum Tube Audio preamps

After some more deliberation I've settled on the SP12 and PH12 kits. They seem to get very good feedback and reviews from those that have used them. And I have found Roy very helpful indeed.

I've opted for the PCB kits only, and they are on their way to the UK. So I'll be looking for a suitable case, transformer, switches and pots etc. Shouldn't be a problem though.

Has anyone on here built these kits themselves? Any feedback? Anything to look out for on the build?

Also does anyone have any sensibly priced valve recommendations on the following? I have in the past used JAN/GE valves but these are getting increasingly difficult to find at sensible prices.

4 off 12AU7/ECC82
1 off 12x4
2 off 6922/6N11/E88CC

I intend to keep this up to date as I get on with the build. Probably with a few questions as I go.

Thanks
SJ

New production JJ tubes are really quite good... The small signal tubes are incredible, the power tubes wonderful.

At the minimum, get a set to start with.

Try Bluebell Audio. They sell Hammond metalwork.

Those should be perfect, thank you.

Anyone have thoughts about substituting the 12AU7 in the line stage for either 6SN7 or 12SN7? Pros/cons?

My previous valve pre was fitted with 6SN7 and it was fabulous....
