A $5.00 RCA 12SL7 in the MK9.

Scary tube! It gives the TS BGRP a run for it’s money!!

Deep Bass, not as dark as the TS but not “too bright” either.

I have a doubt.
The tube in the photo looks like the 6J1P EB am I right?
I have two spare units and I was thinking of trying it on the Fx Audio Tube 03 that has the GE JAN 5654W tube.
Can I make the exchange without damage to the device or the 6J1P tubes?
Thanks.

Thanks Mordy.
There is a source called Radiomuseum. All you do is type in Radiomuseum5654 or whatever tube you want to know about. Then a window opens up with other designations of the same tube, or similar tubes.
https://www.radiomuseum.org/tubes/tube_56545.html
Sometimes you need to search under different designations to get the answer:
https://www.radiomuseum.org/tubes/tube_6j1p.html
6J1P and 5654W don't appear on the same page, but they are both in the EF95 family and then you know that they are compatible.

So after a while, I've been reading a lot about tube rolling and I finally got to tube roll my Little Dot Mk3. I must say, simply amazing. I'm currently using JJ 6SN7 in adapters + socket savers (didn't want to remove the golden rings) and Voskhod Rocket 6ZH1P-EV for the driver tubes. It's a great combo, I can actually hear a lot of new things in msuic that I couldn't before - I'm surprised by this. What I noticed the most going from the stock tubes tho is more bass. It's smoother and nicer sounding but there is more of it. It's a very audible difference with Sennheiser HD 6XX that I'm using. Overall tho, very nice sound and I can recommend this combo! Of course also attaching pictures. Wouldn't win a beauty contest but it's worth it. They look absolutely stunning in total darkness.
