Haha don't worry about experience or all that. No blaming here if you give your honest impressions. Just go for it and describe what you like and what could be improved. The analysing becomes easier as you get more tubes with clearly different sound. I find it great fun to analyse tubes and sound altogether. Gives your senses some workout. Glad you like them rockets.

 

@Coil: Man I wish I had knew about this Mullard deal sooner. Seems like a great deal especially if that is indeed shipped.

I was looking around and found this link, which I think someone has posted before: http://www.audiotubes.com/6dj8.htm

 

pinched waist and D-getter types are definitely the rare crops compared to the rest... and of course the 7308 gold pins cannot be discounted for the military grade!

I already have enough tubes and just won auction on 2 Mullard PCC189 with yellow old style logo (got them really cheap). They should be at least as good as Mullard ECC88 with white shield logo but we`ll see/hear. 

When I get them and Lorenz PCC189 too, I`ll make longer comparing comment along with Philips PCC189.

 

The auction just ended minutes ago and no bids.. was expecting some bidding war at the last 10 seconds! rolleyes.gif

 

anyway, CoiL, you have tried PCC189? Cos I read they are variable gain tubes operating at 7 volts compared to 6DJ8/6922/ECC88/E88CC/7308 which are all 6.3v. PCC88/7DJ8 tubes are fine in certain circuits since their gain factor is fixed despite the similar 7v.. but PCC189 is one that is at 7v with a variable gain factor which I am not sure if T1 can handle?

post #948 of 6344

icecap, I`ve already talked about PCC88/PCC189 heater voltage differences in this thread, they will work flawless with T1. 

I have Tungsram PCC88, Mazda PCC189, Tesla PCC88, Philips PCC189 - they all work like charm! 

 

But I`m not sure what you mean about "variable gain factor"?

Then try to get these (same as my amperex, GAC factory code, single support leg, dimpled disc getter):

Ok, was maybe going to buy these but I`ve decided I have enough tubes already and will let someone else to have the chance (they are VERY rare!). I`m probably going to hate myself later not buying these... here they are: http://www.ebay.co.uk/itm/380582105973?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1438.l2649

You should definitely like them I belive :)

Hi Folks,

 

I got the rocket logo yesterday.  It is a lovely tube.  It gives the T1 a more "tubey" sound, compared with the original 6922EH.  Everything is just more smooth.  On the flip side, transients are better defined in the 6922.

 

In all, I think I like the rocket logo better, but this has mainly to do with the kind of music I listen the most.  I don't think I can say it is "better" than the 6922.  It is certainly different.  smile_phones.gif

 

So, I got 2 rocket logos.  Would anyone like to swap a tube?  Please PM me if you're interested.

I've got a couple rocket's coming as well. Hopefully they'll be here when the Aune arrives (along with the Amperex Buggle Boy I ordered).  I'm afraid this tube thing is going to cost me! ;-)

Anyone who hasn't jumped on the Lorenz PCC88 bandwagon should do so soon, they are a great tube for the money and I have a feeling they won't be affordable for much longer.

I just heard back on this, the eBay store I bought mine from has ties to Aune and they checked with the product manager, 12AU7 is NOT supported with the T1. Sorry frown.gif

Gold lion is actually better now that I have burned it in for a while. Like I said before it is like a mix between EH and rocket. It has warm rocket-like intimate signature, but bass seems to be less boomy and you feel slightly more air in the presentation. I feel like this is a good all-around tube for multiple music styles (but still suits best music that doesn't need that big a** soundstage). I feel like T1s should ship with GL as the stock tube. Even being nice new production tube the GL just is too expensive for what it delivers imo. It's not as much upgrade from rocket and soundwise they are quite similar. So with rocket you get that warm tubey sound for half the price of GL.

+1 and why buy gold lion when you can get NOS tubes for 1/2 the price?

True. That was clearly a mistake from my part. NOS prices are going up faster than those of new production tubes. Well I hope people learn from my mistakes and go for NOS tubes. Been now grinding some of my favourite slow blues songs for over and over (this in flac: http://www.youtube.com/watch?v=xuYWhsjFpNM and this http://www.youtube.com/watch?v=ALU5g6Qqi08) and GL goes definitely deeper than rocket. So GL is not a bad tube by any means, hell no, just overpriced when compared to some great NOS deals you can snipe from ebay.

I would but I already have a Mullard 6DJ8 Shield Logo Gray Plate O Getter on the way. I have indeed high hopes for Mullards.

 

A side note for everybody, Michael Jacksons Stranger in Moscow FLAC is a pretty fun track to listen with wide sound stage cans + tube.

These? http://www.ebay.co.uk/itm/PCC88-7DJ8-NOS-LORENZ-SEL-TUBES-MTCH-2PCS-/390549365471?pt=Vintage_Electronics_R2&hash=item5aee8e62df

Well, I´m hoping that my Lorenz PCC189 will be same good or better because I`m done with buying tubes. Got enough of them. 

When I sort out 4 best of them (2 for electronic music and 2 for rock/metal), then maybe I will send other tubes around for trying for everyone (inside EU).

 

Salvatore, those Mullard shield tubes are great and keepers but when it comes to high hopes - there is always something better out there ;D For me, it`s the closest tube to my amperex and thats why I like it BUT, like I`ve told already, they also have little minus side - whole highs range feel littlebit "flat" and lack of sparkly sound & transparency, but only a little. And this might be only my tube, you never know when comparing NOS tubes.

Those indeed. They are really decent sounding and IMO compete with much more expensive options out there.
post #960 of 6344

Good to hear. What would be the closest sounding tube you have to them? 

 

Only tube I`m still wondering about is JJ/Tesla ECC88. Would really like to try it.
