Ampsandsound Mogwai

This is exactly why I really can’t appreciate the KT88.
I prefer a less powerful but more controlled sound.

I get different results with rectifier tubes all the time. I have good 5u4g’s and less good ones. In general I prefer gz34 with my 6SN7 tubes. Don’t know if there is a logical explanation to that. I have a rectifier tube from Elrog - a 5u4g - and this makes the mogwai sing like nothing else - especially when used with 6SL7. Punch and holographic soundstage. A NOS GE 5U4G sounds kind of congested in comparison. So, even within the same tube category there is a lot of rolling to be done.
Exhausting, but fun when it plays out the way you like.

I seem to agree with your experience here.
Focal Radiance sound better to me from 6sl7 even though the gain is quite high.
I still haven’t tested enough to fully decide but think I also enjoy the 6sl7 with LCD-5 more so than 6sn7.
Never tried the EL34 so would be interested in rolling this tube.
Mite look at purchasing a pair soon.
Any particular EL34 brand you can suggest?
I do own a HD600 but doesn’t get much of my time lately.
I seriously really enjoying the KT88 till I spend some time with them and then went back I noticed no bloat on a few of my usual tracks.

EL 34 B STR Ruby don’t have crazy price and sound very good toy ears.
Check also TungSol.
I’ve no experience with NOS tubes at the moment. I’m trying to explore some combo and check what meets my preferences before investing great amount of money on pricy tubes.

I will look at these maybe get a pair in the future.
Any experience on rolling the rectifier tube?
I found the stock 5u4gb rectifier tube to have more slam? compared to 5AR4.

I have never tried EL34 power tubes I my Mogwai. I don’t know if you were referring to the GZ34 rectifier?
I use a gz34 matsushita.
For kicks you might want to try the Bendix 6384 (cetron or tungsol) power tubes. This is my personal favorite - so much punch.

These sound interesting.
I guess these are a bit rarer to find as they seem to be hard to find here in the UK.

True. They are unfortunately hard to come by.
Let me know when you desperately need to try them. I have small collection.

EL34 and in particular EL34B STR have nearly as much power as 6L6 but sound to my ears cleaner and more controlled without losing warmth and impact.
With jazz music I really love them for the sense of space and room they give to the sound maintaining a good instrument separation and bringing a very clean, noise free sound.

Sounds interesting- can you recommend a brand of tubes?

I have a pair of Ruby with dark red base and they sound better to my ears than other brands.
I don’t think they are currently in production but I’d have to check it.
The TungSol aren’t very expensive and are usually quite good.
Check that the tubes are EL34B and not standard EL34: it doesn’t change a lot but the sound from the B/B STR is better to my ears.
