This is my end game right here: Telefunken EF86 + Tung Sol 5998

Great details and 3D-ish staging and imaging from the EF86 whilst the 5998 provides the power AND bass. Such a wonderful combo. Thank you to those who recommended this fantastic combination. My 6XX has never sounded this good; veil lifted with bass to boot, unheard of in my 6XX till this combo.

I received the GEC A2293 CV4079 power tubes (if anyone wants to try this, also requires an adapter: https://www.ebay.com/itm/1pc-Dual-G...m2f2379c67b:g:WisAAOSw2yVbtq1f&frcectupt=true) and Mullard EF-86's today and am trying them out. I decided to "cleanse" my ears by using some tubes I don't like as much. If these are as close to the 5998's as indicated then it's often very hard to tell and would be best if I had two La Figaro amps for the comparison (which I don't). As expected, the "cleansing tubes" still annoy me and became fatiguing after a while.

The GECs are some great tubes and more reasonable for your budget compared with the 5998. 4 A2293 CV4079 tubes + adapters should run less than $200 vs $300 (or more) for a pair of 5998's.

These definitely sound very similar to the 5998's, open/airy, detailed, clear. Some punch, could do with more (I would say the same about the 5998's). Lively without being fatiguing. Voices are great, male and female. Good for a wide variety of music. So far I've tried classical, classic rock, 70's jazz, 80's pop, and recent pop. All really good.

The Mullard EF-86's are also nice, my only complaint is I prefer the bass on the Philips 6SJ7. I have a Loki, after adjusting the settings all is well.

Worth noting the gain is very high with these, I almost fell out of my chair after switching!

This is a great combo with the HD800 (+ SRD mod). These headphones thrive on clarity and detail which this amp + tubes delivers. After I tweak the settings on the Loki, this sound is hard to beat.

Now if everyone can stop recommending more tubes I will finally stop spending money on this amp! :wink:

Haven't been on head-fi since the site redesign.. great to see some new LF339 users :)

I've had this unit for a few years so I guess I'm a veteran now, huh? *Leans over to check the tubes..* Bendix 60850WB (graphite plate) and Tung-Sol 6DJ7T (mesh plate) as the power / driver tubes, sounds great as always.. although only one pair of the Bendix :D

Closest to the 5998 I have are the Tung-Sol 7236, rebranded as Cetron.. really neutral solid state sound with those power tubes in there. I even rock some Shuguang 6N13PT power tubes from time to time, they sound very neutral too :D

I just saw this on eBay today and I just want to confirm this will work for my version.
https://rover.ebay.com/rover/0/0/0?mpre=https://www.ebay.com/ulk/itm/401699746642
Those work with the 'bright' version of the LF339, which apparently is the default (and rightly so, imo).

If you've got the 6AS7G / 6H13C/ 6N13P compatible amp, this will work. And very well too if these reviews are accurate :wink:

5998 / 7236 / 6080 are also compatible model numbers. Though worth mentioning the graphite bendix 6080WB is not the same as, say, the thompson 6080. They are both compatible but only a few have that truly exceptional sound.

I got my CV4079/A2293 adapters and some GEC CV4079 tubes in over the weekend. Took a few tries to get them settled in. I had some sound quality issues with them originally, but I narrowed it down to being a bad paring with my Telefunken EF 86 driver tubes and my Beyer DT 880. I swapped in a pair of Telefunken EF 800 and had much better results.

This combo is very smooth with, what I think is, the best bass that I have heard from my La Figaro. It is very nice listening to this combo with my LCD-2c and Aeolus. So far, I think I like this tube roll better than my Mullard 6080 & EF 86 roll; which was my favorite and go to before.

I was just using the 6080WB last week before i rolled in the 7236 for a solid state sound.. so solid state that I had to eq the treble down using the DT880 :)

I can try the 6080WB and give a comparison. From what I remember they gave a wide soundstage and imaging, with a strong bass presence.

edit: before I give a review on these tubes, I'll tell you what I paid for them:

Year: 2015
order: Quad Matching JAN CTL Tung-Sol Branded Bendix 6080WB NOS Testing Graphite tubes
price: £195.00 GBP (256 USD)

At the time this was a pretty good price, and for four (4!) of these tubes.

The current ebay listings I've seen are 2 slotted plate 1962-era tubes for $400 USD... these are not prices for tube amp owners, these are collector prices... If you really want this tube AND you also have a tube amp, you could get them. May as well get some 6H13C tubes which can be $35 per pair and realistically, would sound 75% as good as any other tube.

On the other hand, limited supply of these NOS tubes is driving the price up nowadays.. and the bendix 6080WB will likely never fail :wink: And these are the slotted version, which are supposedly better than the solid graphite version of this tube.
