Hi Mikelap, thank you!  You are helpful all the time!
The setup is elegant, but probably beyond my skills in DIY plumbing !  
Quite a bit of precision work there with the brass tubing there, which I'm not too confident!  Haha!

​Atleast the C3G and the 6SN7 adapters can be purchased ready made which is pretty much all you need really ,BUT half the fun is trying new tubes .Have fun.

I will work on the adapters as soon as the materials come in.
I have built the C3g adapters before and would like to work on the 6DJ8 now, and will post photos when it is done!
 
I have a few used Siemens and Russian ECC88/6922 on hand.  Are there any inexpensive (U$15-50 each) 6DJ8 you folks have good results in?  Some of these vintage  6DJ8 can be a bit costly (to me!) which I probably don't  want to spend on now.

I haven't been in the market for 6DJ8/ECC88 for a long time, but I would think that if you are patient, you can find tubes manufactured by Philips, in their Heerlen, Holland factory, often labeled Amperex, and in their Blackburn, Britain factory, often labeled Mullard, in this price range. Also, Tesla-brand tubes might be worth trying.

Hey @MIKELAP it has a balanced output!
 
Don't say that too loudly as we don't want to drag you know who into this thread.
