See my edit.....

 

IMO

Then wait for the time when you can buy the OG's.

 

IMO

Rather than getting some "maybe sorta sounds ok".  Wait.

That way you will have listened to the stock glass for some time and will appreciate the change more.

 

Last IMO.

Buy the glass before the HP cable.  You will notice a much bigger difference.

So should I just cancel the order and get the orange globes then?

 

I can get the OG from '68...

Also I got them at a pretty good discount, too.

Just wanted to make sure you see this post.

 

What do you think?

What do you think?

I've purchased a good chunk of glass from Ron.

If he says they are the same, then they are the same.

 

I know they are both ECC88's and they were both made in Heerlen Holland..... (Oskari, It was Holland in 1968)

 

I'm a brand bigot.

Get the 68 OG's

Slam Dunk.   Ask nelrm6   

 

EDIT....

Only if the OG's are from mercedesman.   

He has the best valve guarantee going.

For a Very First purchase.  Go with Ron.

He will take care of you if anything is wrong.

The sections should match to at least within 10%, 5% is considered 'Select', on both sections of each tube and across tubes.  It's almost impossible to get 100% matching tubes, especially on the NOS tubes.

 

Best to own a calibrated tube tester to be sure you're getting what you pd for.

Hold out until Ron has "O" getters.  A much bigger voice than dimple getters.

That is worth the wait.

Might be an extra $20

post #7900 of 8735

Ok the OG's have the O Getters, just stick with that?

post #7902 of 8735

Ok thanks man. I sent Ron like 3 messages haha. I told him I will need to cancel the Philips tube.

 

So how many hours you think I will be able to use on these tubes, sceleratus?

If they are NOS I would say 5,000 to 7,000 hours.

There isn't a "Life" spec on the ECC88

However there is a "Life" spec for 6922 / 7308.  That value is 10,000 hours

SInce those are the same construction with tighter tolerances for military use I'm guessing 5-7K hours.

The bass line is perhaps a bit overblown in the original recording.  Now in my defense a bass line is the most easily identifiable section of a track. A audiophile you could say is born or drawn through bass and evolves from it. So after a point in said development, if the bass suffers, they may dismiss the rest.

 

So in additional 48hrs I found the base tightened up significantly. But it was still overblown. By my calculations my NOS Voshkod only had ~100hrs on them.

 

To check, I swapped the Siemens back in. I have to say that... RB one of the following is true. One of us is in denial or the Voshkod take another 100hrs to flourish.  As the commander said that the beginning of the 5th element "I have a doubt".

 

I'm going to give them another 100hrs and then compare again. But I tell you the Siemens Cca didn't need any break in time. They just did what they do right off the hop....and then they just got better and.... better and better.  The fact that I picked up my pair for $240 means steals can be had.

 

Putting another 100hrs on them is going to be tough because this equates to a good week of withdrawl.

Good to hear your impressions.  Of course you did hear an improvement with additional play.  The Voshkod will never beat the CCa gray plates, the CCa you bought were most likely used so were already broken-in when you got them. 

 

$250 for S&H Matched CCa Gray Shields?  These Silver shields just sold for $325 on Ebay.  The Silver shields are not nearly as good as the grays:

http://www.ebay.com/itm/Siemens-Halske-Cca-Tubes-6922-E88CC-7308-Germany-Vintage-1960s-Gold-Pins-/360624711075?pt=Vintage_Electronics_R2&hash=item53f6e865a3&nma=true&si=NYFC5gcv%252F2fjo6YXHg%252FjGi2zwqA%253D&orig_cvip=true&rt=nc&_trksid=p2047675.l2557

 

What are you using for a DAC?  I'm running an APL NWO in one system and a Xindak DC-5 in my other.  Tubed DACs - in fact any DAC will make a difference.

The APL is a ridiculous unit with 20 AKM 32bits DAC chip per channel.  http://www.aplhifi.com/index.php?op=digital_NWO_M.

 

I don't have the newest version but an older one, pretty close.  This is a $20,000 DAC when I bought it.  It is very detailed and musical.  I'm using a pair of Supra Sword IC from the DAC to the Lyr and Woo.

 

The Voshkods you have are newer versions I believe 1983?  I have the 1979s and they are magical!   As I said, I compared them extensively to the Amperex Orange PQ and the Philips SQ Holland Halo Getters and on my system they are clearly better!  And that was the 1980s Silver shields.  The 1979s Silver shields are better.

 

I have been scouring the E-bay Russian and Ukraine dealer for more Silver shields - none to be found so far.  I have some 1975 grays coming and 1967 Reflector Rockets.

 

If anyone wants my Philips SQ Holland Halo Getters they're for sale - they go for $350 on Brent Jesse's site - I'm selling mine for $150 1960s date codes PM if interested.  They'll go up on Audiogon this week.  The Voshkods are too good.  I have the SELs PCC88 coming, so I'll give them a listen.

 

I'm liking this headphone thing (wife does come running downstairs to tell me to turn down the volume when I crank it up!)   I will probably be selling the WA6-SE and be buying a Woo Audio WA-5LE or if I can scratch together the funds the Manley Neo-Classic 300B and be done with it.  I do believe the 300B is the ultimate Headphone tube...then the tube rolling begins all over again!!  I'll keep the Lyr as a portable system for travel.  The Manley takes a 6SL7GT and the Woo WA-5 6SN7, so I don't want to go over board on the 6922s.

Hello everyone.

 

I have a serious question for everyone.

 

How hard is installing Uber board for Bifrost?  I have some technology experience but not expert.

 

Thanks
