It is a solution for low budget or where tranformer with 110/115v and 6v secundary are not available. With 6v sec. of the maintransformer connected to the 9v sec. the primary of the second transformer generate 110/115v. This solution cost for the 2 transformers about €22. The schematic can handle between 130 and 170v anode voltage.

Unfortunately not. Here's the article, fairly detailed description, but I have not been able to find the schematic.

THE CLEAREST LINE STAGE OF ALL

I think I have all the Vacuum Tube Valley magazines, and I can't recall that line stage being mentioned. However, I certainly don't have a photographic memory - though I did go through all of the issues in the last couple of months.
 
Not the schematic from the article but the clearest tube linestage as stated by a lot of builders.

Call it a wire with gain.

6N16 12x preamp srpp/cathode follower with printed circuit board design.

This is very interesting - I've been looking for a buffer for a DAC and this is exactly what I'm after. I assume it's the topology rather than the valves themselves that make it so clear? I ask because exotic valves aren't easy or cheap to come by in South Africa, but the more common ones are. I have an E88CC in mind....

Do you not have ebay in South Africa? The 6n16b-v tubes cost about $1.50 a piece from Russia or Bulgarien.

The problem isn’t ordering and buying - our postal services are in a shocking state and it can take 3 months for something to get into your hands, and sometimes it never arrives. The solution is expensive courier services which ends up costing a lot. I can get the ECC family in a day or two quite reasonably

ECC 88 etc do not work well in SRPP stages.


6N16 is more crisp.
You will like it,i do.


Koifarm,nice to see your still around :)


Back to topic.

Yep, it was a 4P1L, DHT
But a hell to make,lots of howling tubes to silence.


Now working on a 6V6 preamp with fixed bias ,it is close to DHT and much easier to make.(the last picture)
