Ok now that I have bought a new ipad, I can used my explorer 2 again, with full MQA rendering. For the LCD 3 it's perfect for loud modern music. But for classical or old jazz recording I might need an amp to boost that level. But for Billy Eilish it's perfectly suited, and I listen to headphone...

Thanks Boss for your recommandation and I agree, I enjoyed that combo to death! But I am still enjoying Telefunken 6080 and EF86 too! Different flavour for different style of music ^^

Did some tinkering inside my amp! Still LCD3 with 339 is my best setup of all times!

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...

Nice! Are they greys or black plates? I saw a pair going for less than 80 yesterday! For my LCD3 I think they are just the bomb for all gendra of music. I love the details too ^^

Its from ali express : https://fr.aliexpress.com/item/1005001593504884.html?spm=a2g0s.9042311.0.0.27426c37lvOeFm Enjoy it's only 3 euros!

Thanks to you for offering such a nice and cheap upgrade for all of us!

I tried the elevated heater, the hum is now minimum of the minimum, and should never be a problem anymore for me. Super happy! It is still not still tombstone silent when volume pot is wide open, but it's pretty much as good as can be. Practically hum is now a non issue for the 339. But looking...

Here is my cheap chinese amp (True Blood 5F1)! It was wired point to point so it's kind of WOW when you consider I bought it only 300€ new! I just changed the speaker and rewired the rectifier from chinese 6Z4 to NOS Tungsol 6X4, and score! I slipped in a Telefunken ECC88 and a RCA 6V6 and now...

I think I need to do my homework before modding the 339. I use different drivers (6J5, EF86, 6SJ7) so a fixed bias might not be ideal for me! I might roam in your DIY thread and ask you questions though if you don't mind ^^

Oh it was very easy, i can post a photo tomorrow to show how it's done. First empty the power left in capacitors on both sides with a resistors. It will really hurt you or tickle you at best If you don't. Then... Just need to wire two 100ohm resistors to both heaters, ground the center tap, and...

You got me interested in trying the gyrator to load the 6j5!😃😃😜 Thanks L0rdGwyn! Yes there is a tiny bit of hum left so I will try the elevation!

I see that's a lot of amps! I was wondering why those 6080 prices skyrocketed in the last decade!😁

I wonder what other 6080 tube amps afficionados are loving the Bendix..

Ok good news for those who have hum issue. For me i have some hum with ef86. I like to listen to 339 with my Meridian 861 DAC at very loud level! Usually i use my 339 volume at 12o'clock and up. So.. I tried @L0rdGwyn first mod for the darkvoice which is the virtual center tap for the heaters...

I want the TU8600! Will you source it second hand? It's pretty much sold out as far as I know.

Your DIY thread looks epic i need to find the time to read it all!😁 I have so much to learn from you!

I still have the same soldering iron than when I was in middle school where we were acquainted electronics and soldering basics! Those were useful courses!

Solid state for summer time and tube for winter?!😁 I may cop a SS amp for summer soon! 339 will be too hot

Just tried the Miflex as bypass caps for the output coupling caps, and the last caps in the power supply. Note that I use SCR mkp film caps 200uf per channel inside the center metal box on the 339. I am really positive, the improvement is noticeable. I tried on one side first and the sound was...

During normal volume level, say less than 50% you will never hear any kind of hum for sure.

Thanks again LG. I have understood your mod and i will be careful. Will report here if it cures it. I enjoy and respect the 339 and i am just searching a way, if any, to improve it gents!😃

I just tried 3 pairs of drivers. The hum is the strongest around 75% max volume then goes almost silent at full volume. The hum is not dependent on the tubes actually. It's the same hum and level for those 3 pairs.

For me it's hard to detect the hum at full volume in during the day. But at night i can identify the hum better when everything is so silent. With hd800 ad hd650 it's hard to hear the hum at full volume but if you concentrate you can, plug and unplug the jack. With lcd3 though i can detect the...
