I was looking at the "Pasta Makers" - what adapter do they use? Do they need any extra power?
6J5 adapter is good. No extra power required.

Assuming they're the Langrex ones, they're some of my favorites in my Glenn OTL so I've ordered 2 more and adapters for my Envy. More noisy than most of my tubes though.

The 6c5 has less gain value than the 6j5.

If you grab a pair let us know how they are!

I've heard they're prone to noise too, which is why I haven't grabbed a pair myself

Current bass champs are these Fivre 6C5 Pasta Makers. But more sophisticated top to bottom. :ksc75smile:

I a have a pair of the ST version of the Fivre 6C5G so a no-go in the Envy unless I snag a second pair. I love the Italian (I think) tax stamp on those!

Now that it’s come up, I recall my Fivre were not stone quiet but sure were great bass monsters even in a modest Garage 1217 amp.

Fivre wins the beauty award in my book with those tax exempt stamps. I don’t have the 6C5GT style Langrex sells, but can confirm the 6C5G (ST shape) sound fantastic. I have two pairs and one is rather noisy (still sounds good) and the other is silent. I think both are smoother than the gray or black plate Fivre 6J5GT but they all have that characteristic lush house sound. I have a Spotify playlist devoted to them called “creamy Fivre faves”.

Speaking of Fivre, I’m excited to try these 12J7GT when my amp/adapters arrive. Love the stamped metal bases -can’t quite make out what they say:

Just out of curiosity, have you tried resoldering the pins to get rid of the noise?

I got mine too! Will need to order some adapters. I'm debating if I should get ones for the 8d2 as well. If I were smart I'd just stick to the *sj7 adapters for now.

Maybe not the right place to ask, but on the topic of pentodes, I see vt49 converters, may I confirm they are safe to use in a 6sn7/ecc32 slot?

Yes, they are safe to use. Have 300mA heaters, same as 6J5 - despite the poor electrons having to swim past so many grids. :sweat_smile:
I honestly just want to get a quad or 2 just for curiosity, they look pretty solid

I have one STC 6J5G that was prone to hum. I also have one Sylvania branded 6C5G in a metal envelope:
Luxor 6C5G.png

Luxor was a Swedish company manufacturing radios and other stuff. It was pretty common to use this 'shielding' in radio sets. Unfortunately this Luxorvania 6C5G died on me due to failing heater. I tried this metal cover on my STC 6J5G and it is now dead silent. Maybe these Fivre 6C5G and GT would react the same to proper shielding? The shield is connected to the pin to the left of the key when you look at it from the bottom.
