A bit of background: I've been into hi-fi kit for about 20 years - bought my first budget kit when I was in my early teens. Since then I have been through a huge amount of kit - sometimes making steps forward and sometimes backward. I've done quite a few DIY electronics projects before, but this is the first time I have undertaken a valve pre-amp project. Maybe not a sensible place to start, but we will see. I'm an engineer by trade - graduated about 10 years ago, and have my own well equipped workshop - but it's mostly full of custom motorbike and car projects. I've built my own ECU's for these before.
I've always been interested in electronics and I've done a lot of reading on the subject of valve electronics recently - but obviously this is no substitute for experience. However, we all start somewhere
The reason for wanting a valve pre is that I really miss my old 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 the VTA equipment and was impressed with the write ups.
After some more deliberation I've settled on the SP12 and PH12 kits. I have found Roy very helpful indeed in the short email exchanges we have had to date.
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 major problem though.
First subjective question - 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
Also is anyone able to tell me approximately what sized enclosure I need to be looking for to fit the SP12 and PH12 in sensibly?
I intend to keep this up to date as I get on with the build. Probably with a few questions as I go.
