That's the strangest tube I have ever seen.

Replace them a lot in European consoles. Damn things are :censored: expensive!!!! About $120/ea CAD landed (depending on what our $ is doing that day, has been anywhere from $90-$130). Then our markup has to go on that.

I bought a pair used but in good condition for about 150 SEK/each ...

Also used in a Hagström guitar amp.

The 6N7 could make a good PP amp low power of course. Two pentodes in the one metal tube. The nice thing is they are black metal tubes. Very sexy.

I am using the 6N7 as driver tubes for the 6CB5A build with both sections in the tube tied together.

On rare occassions I have been considering doing constructing a SE-amp with 6L6, but I have more or less ended up with to designs that tube in PP-mode. However would look into something like a Darling with 6L6. The sister forum www.diytube.com has a version of the Darling but with 6L6 instead of 1626. As I am extremely lazy I would go for a ready made design that looks reasonable.

Soundbrigade I registered with tubediy. Do you have a link to the Darling 6L6 schematic?

I have read through this thread and this amplifier sounds like the perfect next project for me. I am not locating the schematics for this, perhaps I missed it. Would anyone have a link for this?

Thank you,
