There's something a bit magical about the 26 in this setup - the soundstage is big and wide and the sound is very mellow with absolutely loads of low level detail and lovely tone. I'm using globes, and I'd advise on those as a preference.

7193 was always my favourite indirectly heated tube and I used it up until I replaced it with the 26. It does have useful gain. I haven't used it for a while, though. My memory was that ultimately it didn't match DHTs.

Yes, that is why I refined the op point of the 26 and glad we both end up on same one! I used the globes ones for 3 months and now I'm back on a pair of Sylvania NOS ST. They sound very detailed and a tad less warm obviously.

I like the 7193, but My 45 SE is not ideal and I'm working on other options such as 6e5P driver to push the 45 in A2 to deliver about 3W. Will see, but can't do anything until I finish my 4-65a SE. Can't stay without music!

Has anybody used other equivalents to the LL1660 in approx 1:1? I'm thinking LL1635, LL1621 etc.

Can anybody comment on how much better the amorphous LL1660s are?

What's the next step up in sound from the LL1660, while still maintaining enough primary inductance for a 26?

+1 on the Sylvania ST! I think they are more accurate.
Andy, maybe a special order from Sowter?

You will get controversial opinions on this. I don't like them. Too many of them in a system and the colors get washed out.

For 1:1 still the Tango NC20, hard to beat
Or the silver version LL1660Ag. Haven't used it yet, but a 10Y linestage with the silver transformers is planned for March/April.

Best regards

I haven't built a 26 linestage since then. Too many other projects in the pipe. I have sold several pairs of these and got excellent feedback so far. But Andy is looking for close to 1:1 ratio. These offer 5.6:1 , 2.8:1 or 1.4:1

Best regards

Thomas
