Hi maybe someone can help me.

I switched power tubes and when I put my headphones in I got a pop in the right ear. I took the headphones out tried them in my ss amp and the headphones are okey. Switched all tubes on the amp but now there is no sound in the right era cup.

Any Idée what have happend to the amp?

-Had warmed it up 30 minutes.

-Was thinking about fuses but both indicator lamps goes on when turning on and all tubes are gloving both sides.

-The tubes I switched to was working fine last week.

Thankful for any help because I like this amp a lot and dont want it to die.

Maybe some cables inside needs resoldering? It is point to point connected and soldering sometimes is not top quality in this amp. Not a big deal for tube amp doctor.

This happened to me and one of my friends owing La figaro and i understand is not very unusual with this amp. Not a big pain though

Yep, this happened to me also, back in November 2018. I had to send my amp out to be repaired and it was just some re-soldering that needed to be done. The shop went a head and touched up some of the other solder points as well. If you don't have a local shop and are looking for one, let me know and I can recommend who I used.

I think I made some posts in this thread back then to about it.

What's up everyone! I haven't put a foot on headfi, too busy rocking my LCD3 with LF339!
Anyway, I was wondering what it I would bypass all the power caps in the 339, and due to size constraint, I couldn't pop the copper Miflex I really like, except for the last power cap for the drivers, and for the output coupling bypass caps!
I love the results, and for the modest cost of this mod, I am really happy with the upgrade. The sound is slightly more clear and defined. I feel there is less smearing overall. Really happy here!
I could be delusionned somehow like with all things audio, but I did test session of before and after, and the gain is really noticeable.
Those Miflex cap were like 1€ each, so...
Oh and I swapped the mistery white box driver bias for Riken resistor and Nichicon Muse cap. After trying many values, I agree with Yuking's taste and stay with his values for the bias!
Still enjoying the elevated heater ground by the way. It's a must!

Cheers and enjoy (and mod) your lovely 339!

@telecaster looks really stunning Maybe I will go back to La Figaro at some point, just need to find some good headphones for it.

The black version of La Figaro from last drop seems nice, but I guess there were some problems with delivery...

 

[bpiotrow13]

Thanks for the tips. I will let you know hos it works out!

Any news?

Any news?

I leaved it on repair some weeks ago. He fixed the problem fast but I have not talked to him so I dont know what the problem was. Im going to pick it up in 2 weeks when I visit that town the next time. Repair costed me like 90dollars.

I let you know what the problem was when I got it back

Good it went well. Seems like something simple like soldering, but would be good to know.

Good Afternoon,

Who has experience LCD 4 with the figaro (black version)? Drives well? There is enough power? (11oclock for example)

Are the default stock tubes good?
It is possible to get the deep base (low notes) from LCD 4?

Thank u

I wonder if anybody tried, the difference in price is extreme. However, many tried and even use as a main setup La Figaro with lcd3f and it sounds super. I used to have this setup and can confirm.

As for tubes, stock ones are not bad but as with tube amp upgrading may make a difference.

I got the new 339i off a friend like new he bought it on Dec-20 and he said the stock tubes that it comes with are rubbish,
I have the Cetron-7236's and Red hot RCA's. And NOS Mullard 6080 at this stage.

What are the stock tubes now? I used to have older, silver la figaro.

 

[Yetiman72]

Not 100% sure I never looked at them, @UntilThen would know.

 

[UntilThen]

They are 6Ж4С (drivers) and 6N5P (power tubes). I don't care about these tubes.

Get yourself RCA 5693 / 6J7 red tops and a pair of Mullard 6080 or Cetron 7236. Like in this picture. I did a comparison with Auralic Taurus Mk2 and to my ears I prefer the LF339i with LCD3f over Taurus. Both good amps but I prefer tube amps.

Both amps are no longer with me. I've move on. That beautiful LF339i has gone to Yetiman.

Did UntilThen supply the EF86 adapters with the 339i?
The ones from Yuking are superior and you get more gain and richness in the EF86/E80F/6084 tube family. Valvo, Mullard, Amperex are good choices for these tubes.

 

[UntilThen]

Stunning pictures Galapac. No is the answer to your question because I am keeping the Mullard EF86 & Siemens EF80 and both EF80 to 6SJ7 and EF80 to 6SJ7 adapters because I will get another LF339i later.
