Little Dot Tube Amps: Vacuum Tube Rolling Guide - Page 298

post #4456 of 10502

Speaking of Christmas - or whichever holiday floats your boat, I don't want any trouble here lol - I got my filtering power strip a bit earlier than I expected, which is good since it'll allow me to familiarize myself with the new sound before I get all those cool tubes in a week.

 

Same product as - may his soul rest in peace - Acapella11 mentioned months back, this:

http://www.amazon.co.uk/Tacima-Conditioner-Frequency-Interference-Filter/dp/B000PS5700

 

Yes, it's cheap; yes, it only has UK sockets (I live in France, use different plugs and still bought it, so it just takes a little creativity); no, I wouldn't use it with non-220-240V AC power; but yes, it makes a COLOSSAL difference!

 

Honestly, I had expectations that it would at least make a difference with the Little Dot plugged into it - after all, removing noise from power is never bad - but it's rare that a brand new product I add to my sound chain makes a such a difference that at the very first second of listening I'm like "Oh. I see. And I was missing this all these years, huh? There must have been something wrong with my head... Is this really happening? How can this sound so good? And for £30?!? Holy ****...!!"

 

Anyway, I won't go any further since this is largely irrelevant on this thread, but I strongly urge you to get a similar product. It made enough of a difference with just the LD plugged into it, but when I added the DAC to the filtering power strip, it felt like I multiplied the price of my system by 3... You may think I'm joking or overreacting, but you all know I usually don't muck around. The difference is HUGE and makes me wonder just why it took me that long to do something about my power... It feels like I'm listening to a different system right now, and it's better than mine!

 

Lesson learned: Filter thine wall power.

Interestingly, the plate voltage is quite a bit higher than a 6SN7 (81.2) or a 6N23P (85.2)

 

And the grid voltage is lower than a 6SN7 (3.2) or a 6N23P (2.6)

 

These are pretty close to perfect values actually, right?

 

That makes me want to try two C3G pentodes, now that we know that the cathode resistor is largely irrelevant - for all intents and purposes.

Technically, it shouldn't make a difference since nothing is supposed to be plugged on pin 7 anyway, or pin 6 for that matter... But yes, EF95 would be good practice, on the off chance anything goes wrong.

Hi everyone,

 

Merry Christmas to all.

I just have a quick question:

I ordered these tubes from Yen Audio on Ebay:

 

http://www.ebay.com/itm/2x-EH-6H30Pi-Matched-Pair-Little-Dot-Amp-Mk-III-IV-SE-/290581469274?pt=Vintage_Electronics_R2&hash=item43a801585a

 

http://www.ebay.com/itm/290613497027?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649

I ordered these things on December 9, 2013.
 

After checking with the postal service, it turned out that the package was rejected by customs and sent back. I live in Toronto, Ontario, Canada.

 

 

I'm wondering if this has ever happened to anyone?

 

I can't think of any reason why customs would reject a set of tubes.... or is it probably something that the seller forgot to include on the packaging?

 

I suppose I'm just wondering if Canadian customs has some sort of policy against vacuum tubes that I'm not aware of :P

Any help would be really appreciated.

 

Thanks in advance,

 

 

sam

Hey Sam, Merry Christmas i ordered once from Yen Audio and there was no problem with customs im in Montreal .In a way customs did you a favour because if you read the thread youll find out soon enough that you dont have to pay crazy prices for matched pairs because first of all you dont need match pairs for the driver tubes .and if you go to page 77 youll see different tubes that are better than the typical tubes you see on page 1 of the thread for the most parts these tubes start from about $3.00 to around $10.00 approx. So no need to pay a fortune for tubes, not on page 77 anyways .Welcome.

Hi Sam6350,

 

Agree with Mikelap that the customs did you  a favor. First of all, as far as I know you are covered by Ebay's guarantees, and you should not have any problem getting your money back.

 

Secondly, you can get better and cheaper tubes from other sources. A pair of 6N6P-IR tubes will cost $39.00, and it seems that the consensus on this forum is that these are the best power tubes for the buck.

If you want the Voskhods you can get the same ones for $14/pair. Another higher recommended tube is the Ei 6HM5 that you can get for $10/pair.

 

(All prices are from Ebay as of today, and include shipping)

 

There are a number of Canadian members on this forum, and except complaints on long delivery times I did not hear that packages were returned by customs.

 

Good luck!

Mike and Mordy,

 

Thanks alot for the help. I'm a bit of a noob to tube rolling.

 

Just to follow up.

I'm using a Littledot MkIII amp, so I'm assuming that these tubes will be ok for that amp?

Also, I'm assuming that these are what you're referring to Mordy?

http://www.ebay.ca/itm/6HM5-6HA5-EC900-export-quality-audio-triode-tube-NOS-FREE-SHIPPING-/300879467071?pt=Vintage_Electronics_R2&hash=item460dd0523f

Lastly, is this the same thing as a 6N6P-IR? or does that "IR" make a big difference?

Thank you guys again for all the great advice,

I have been listening to a 1951 National Union 6SN7GT recently, and I must say, this is one very fine tube.

As Mordy observed in a private message, 6DJ8-type tubes are cooler and more detailed and the octals are warmer and more musical, and I think this hits the nail directly on the head. If you begin to roll 6SL7s and 6SN7s after having lived in 6DJ8 land for a while, you will definitely notice this difference.

 

Of course, too much reverberation thickens the sound and obscures detail, but the National Union seems to get it just right. A touch more reverberation creates a very large and spacious 3D stage with considerable depth. Vocals are slightly forward and warm without losing mid range detail. Moreover the bass and treble are very good. While the National Union lacks the ultra detail of the premium 6DJ8, in my opinion, it makes up for it in musicality. Don't get me wrong, I still enjoy listening to my best 6DJ8s with their amazing detail, but the musicality of the 6SN7, done right, as evidenced by the National Union, is very enjoyable too.

 

Frankly, I was not impressed with the 5751/12AX7 or the 6SL7 tubes, but judging from my experience with the National Union, 6SN7 tubes are definitely worth exploring further. I gave $20 for this tube, including shipping, so not cheap, but not outrageous either.

 

With the caveat that this is a 600ma tube and an external heater circuit is required, strongly recommended.

Hi Sam 6350,

 

The first link is the right one for the Ei tubes. Although he asks $6.95 a tube, he accepted $5 from me and maybe $4 from someone else on this forum on Best Offer.

 

The second link is also the right one. I got my tubes from this seller who is very nice to deal with. The price is good. If you want to save money, ask how much he will charge you for 2 tubes since this offer is for three tubes.

 

The there is a very big difference between 6N6Pi tubes and 6N6P-IR tubes. If you do a search on this blog you will find a comparison between some  Little Dot MKIII driver tubes on page 183 post #2745.
