A single stage amp ?
#31 Here are 2 examples of single stage in the same amplifier
Romy uses 2 single stage amps with his DSET concept in the fundamentals and HF channels:

This might be a dumb question, but how can you have 1/2 a 6C33C ?
As I read things the anode, cathode and grid are internally connected, with just separate heater supplies for each half.

There is a seven pin triode from Russia that is in effect half a 6c33c, I used it in the regulator for the first LCR phono I built, can't remember the number at the moment.

Not only you can use one half of 6C33C (babuška) - preferably heating just one cathode (eventually swapping tubes between channels when they start getting weak) - but you can apply higher B+ and use the tube with a different set of parameters, essentially plotting the loadline in a different part of the curves.
This gives it a different character and sound. After my initial suggestions, some have applied the concept and regardless of the lower power liked the approach more.
I prefer 6AS7/6080 and 6336.

With the nipples at the top, it is more like mamuška

Well, it is of cause highly predictable if the objective is to masturbate with different tubes, placing with measuring equipment, stupid conversations about different part of the curves for IDHT, desire to share with other online how you were abused by an electrician in your childhood and endless suffocating in soldering smoke. There is no different part of the curves for IDHT and there is no higher B+, there is just no need for it in real life where objective is to make amp that gets the best from the given tube/topology and forget about it. If the objectives is the keep annoying yourself and another with endless, pointless and incredibly stupid experimentation with electrical application then for sure one can run any tube at any voltage and then waste 2344564 posts elaborating how wonderful was it.

The triode you mean is 6C41C that is "kind" of half of 6c33c, however it has very bad sound, not even remotely close to 6c33c.Nick wrote: There is a seven pin triode from Russia that is in effect half a 6c33c, I used it in the regulator for the first LCR phono I built, can't remember the number at the moment.

Not heard one myself, but I read of an OTL amp using that valve and the review was very positive.Romy The Cat wrote:The triode you mean is 6C41C that is "kind" of half of 6c33c, however it has very bad sound, not even remotely close to 6c33c.Nick wrote: There is a seven pin triode from Russia that is in effect half a 6c33c, I used it in the regulator for the first LCR phono I built, can't remember the number at the moment.

I think that the 6C18C is what you are talking about

The world looks so different after learning science. For example, trees are made of air, primarily. When they are burned, they go back to air, and in their flaming heat is released the flaming heat of the Sun which was bound in to convert air into tree.

It is incorrect. The 6C18C is the same two plates as 6C33C and they are direct replacement. In the image you linked there are two 6C18C on the left, they are without the nipples. The 6C41C is smaller tube and in the first image on the following thread two right tubes (smaller) are 6C41Crowuk wrote:http://www.goodsoundclub.com/Forums/Sho ... =6140#6140
