OK so they could be one Tung-sol 7236 and one Cetron 7236 and as long as they are built the same way, they will sound identical. One of them is more often just a rebrand of the other.

Ask to try them in the amp and hear for yourself. 90% of the time if they are the same model they will sound the same.

PS find out what 6080's he has

Will do. I told him I had Mullard 6080s and he said he had some, but he may have just meant 6080's. Is there a specific 6080 you are interested, Benedix 6080s if I remember are supposed to be stellar.

Mullard's are supposed to be good, not sure if I want them right away but it's always good to know where to get a pair!

You really should read the 6as7g thread, it's only like 3 million pages or so but has great info and it will answer a lot of your questions

While I agree, those massive threads are so time consuming and I do intend to go through it soon. I think a general guide would help more than a thread. Anyway, think I'll go to the thread now and start wadding through it. Cheers.
 
Edit: read from page 1 to 95 so far today! A little overload so need to take a break. Yes, it does help a great deal. My issue is not really knowing the tube equivalents so sometimes I get a little lost.

Finally, my 339 is purring like a kitten. Damn does this sound fine with the HD 600. My local tube guy, who is an expert, older gentleman found me an absolutely perfect matched set of 1940s, RCA Radiotron input tubes. He told me on his very high end testers (he used two, an acceptable value was about 1600, these both tested over 2400). He says these outclass any Marconi tubes by a considerable margin. Anyway, finally getting to listen and I'm happy, a very natural presentation for sure.

Deleted pictures, they were pretty crapy.

The 339 is fine with my 32ohm, 100db sensitivity ONKYO A800 and it seemed to love the LCD2F as well. I'm not detecting any loss of bass control, if it is there, it is subtle which means rather meaningless. Damn does this amp throw heat! Listening to Fleetwood Mac - Rumours 35th Anniversary reissue is amazing.

Took some night shots for practice, plus tube glow is awesome looking. I need a real camera.

The RCA 6j5g are top tubes! Nice find! I love best US 6j5g coke bottle, but for me its the UK military that stole my Heart. For cheaper and more availabilty i can vouch for the GEC L63. Very good tubes.

Rare and unheardin 339 are Marconi l63.. they are pricey. Your tubes are 6j5g, not 6c5. Also I never heard them but there are hints that real 6c5g mesh plate are the balls for tubes amps, but it's just guessing!

Yes, my bad 6J5G tubes, and I'm enjoying them. I actually replaced Marconi L63s as one of them was bad, damaged during shipping of the amp. I will see if I can find some mesh plate 6C5G tubes from my local source, you never know, might get very lucky. Cheers.

I have been enjoying this thread's activity recently but have been travelling so unable to participate.

I am about to list a matched pair of Chatham 2399/ Tungsol 5998 tubes for sale but thought I would make them available to 339 owners first . They are in excellent condition, only lightly used, were appraised and approved by Gibosi via PM, and are arguably one of the most sought-out tubes in the 6AS7G family, particularly among BH Crack and Elise owners. Pricing will be very fair. PM me for details.

How come you're selling them if I may ask?

I am selling other items as well--because something unrelated to audio has come up, and I need the money.

I may be selling my HD800 as well.

I'm sure I speak for everybody here and hope that you aren't facing a crisis of some sort; and it goes without saying I hope you are doing okay. Cheers.
