Dark Voice 339 - Page 64

post #946 of 2404

Found a couple of US resellers charging between 16-20 USD/piece.

 

Also found a listing of a pair of Tung Sol 7236's on eBay... although the price is quite ridiculos (168 USD)... I read that they are more prone to arc than 5998/2399... Are there fuses that prevent current surges and headphone-damage in the LA339?

Found a reseller that had everything I was looking for... Now let's see if i get a rebate...

 

1 pair of 6AS7G

1 pair of 5998

1 pair of 7236

1 pair of 6SJ7GT

1 pair of 5693

 

... Then, it's over. No more audiophile-related expenses this year.

EF80? :)

Your amp has arrived?

post #949 of 2404

I might as well add a pair of 6BX6/EF80... only 5 USD a pop.

 

Nope, not yet. Leaving for a holiday to Norway, so some fun stuff should await me when I get back. ;)

Do get the EF80 by Telefunken ;)

I can't go to sleep, I keep listening to "one more song".  The midrange is hypnotizing, they are so clean and musical at the same time. Mellow rock with strong vocal tracks sound so good. I think I even prefer the LCD-2 for this genre with the 339 over the SX1250 (I never thought that was possible, although the soundstage is smaller).

 

A picture is worth a thousand words they say.

I may have a problem again, this time a big one.

 

I heard a pop sound on my right channel, and after some seconds it sounded as it loose some of the bass. I decided to turn it off.

After some minutes I turned on again to see if it wasn't my mind playing any tricks, and now there is no more right channel, again.

 

I may understand this failure (dead channel) because when I went to a technician he said it could be repaired for a while, but that I should replace some os its parts with other ones with different values as soon as possible so it would not fail again. So I asked him to import some good quality parts and to notify me as soon as it arrives. Unfortunately these parts haven't reached his company yet.

 

I really hope my brand new (2 months old) US$ 550.00 recabled DT880/600 haven't blowed its right driver. It replaced the same headphone that blowed its left driver after an accident with a arcing tube on my 339. At that time I don't think it was a amp issue, but...

 

 I will try to hear my headphones on a friend's house tomorrow to see if there is any imbalance with left/right channel. If this is the case I'm going to be very mad.

Loud pop is usually the tube?
 

post #954 of 2404

I don't really know what your tech said but the AC from your power outlet is transformed into DC through the rectifier before going through the power resistors. That resistor must have appropriate wattage and thats the end of it.

I went to bed last night after posting here.

Today I tried to change the power tube first and my (theoretically) NOS tube with a few hundred hours is dead.

Now, with the same volume on both sides, is obvious taht the left channel is louder than the right one. The good thing (at least for now) is that if I raise the volume on the right channel it does not distort, as it happened before when I blowed my last headphone.

Monday I'm going to my friend's house to see how my headphone behave there.

I told you, well now you need two new equally strong power tubes again :D

Question for Keph, Telecaster or Ultrainferno; What is the best route for buying a 339? E-Bay? direct from Yuking? My HD650's are curious.

 

Thanks!

post #958 of 2404

Longbowbbs, i would say direct from Yuking.

Are you sure?  that what I was always told myself, but I ended having more audiophile expense in the same year, ... again ...

post #960 of 2404

@Longbowbbs: I bought it from a shenzen store on ebay and have 1 year warranty but as I change every single part in the amp it's not under warranty anymore! There was a sale on that store not long ago and it was pretty bang for the buck, but it's over now.

Direct from Yuking is very safe for sure. But they don't speak english well, or maybe the hard communication is because I'm not a direct consumer of his...

 

@Redbull : Sadly I too got bitten by the tube syndrom and have way too many purchased! It's not that expensive if you look at it from the bright side and it's a hell of a fun!
