Do you have availability of transformers? That will help considerably!

If you can get 12AX7 and 12AT7, I'm sure you can get 12AU7 (ECC82) also. Have a look here: http://gyraf.dk/gy_pd/g9/g9pd.htm

It's not cheap, but it's good.

Best regards,

Hi,

You can make a fine totem-output with a 12AT7 instead of 6N1P. Just don't expect to be driving any 600 ohm lines 😉
