what is Jason's opinion about using pcc88 in Lyr ? there is wrong voltage (7V instead of 6.3V), are you sure this is safe for the tubes / amplifier ? I know about  auto bias in Lyr but still ...

My guess is Jason will tow the factory line.

 

The tube is receiving the voltage, not generating it.  Hence the higher V rating will not harm the Lyr.

What does happen is 6.3V is enough heater voltage for a PCC88 / 7DJ8 valve to work.

 

The spillover benefit, supposedly, is that a PCC88 should last longer.

EDIT:  You aren't cooking the heater as hard.

question.

 

is this right tube for lyr?

Yes.

It's a 6922.

 

That is a valuable / rare pair of tubes.

There are 21 bids at the moment and I expect it will close near $500

 

I believe I read that the pinched waist were more of a mfg. defect.

My suspicions are the value is more in the novelty rather than the sound.

At least the incremental sound benefit from a $300 set of tubes.

 

EDIT:

I think they would be wasted on a Valhalla.

They may shine in a Lyr.

Save the $500.  Buy the Lyr.

Yeah they will work fine for the lyr. However I don't know anything about eBay tube sellers so I can tell how legit the tubes are.

Thank you....I was bidding and I wasn't really sure about this tube.

I should just stick with cheap tube.  deadhorse.gif

iam it maybe more than novelty, member lord soth likes them more than lorenz Stuttgarts, he even had the nearly impossible to find lorenz cca. Haven't seen him on the thread in a minute,but if he sees this maybe he can expand on the benefits of the old amperex.

I just reread the auction.

I only read the Headline before.

 

Looks like they are "very" used as well.

They shouldn't go near $500 but they might no sound good at all.  Stay away.

 

IMO... Make an educated decision and look around for a nice "moderate" pair.  $150 to $200.  

Keep asking about tubes on the thread.  I don't mind giving you my 2 cents. Others have a far more extensive collection.

 

@fear pointed me to the E188CC La Radiotechniques I was gushing about above.  Although mine just happened to be made in Heerlen

they still sound like nothing else I own.  Labeled "RTC" 1965 large "O" getter gold pin, NIB.  Might just be "SQ" Orange Globes.  No matter.

I paid $140, shipped from Spain.  I consider those a good deal.

This is merely an example.

 

However if you should happen to stumble upon a bargain and post it, the tubes will no longer be a bargain.

We won't do that to Gustav on his first tube buy.... will we... guys evil_smiley.gif

 

I have zero experience with a Valhalla and I am terrible biased to what I own.

You have LCD2's.  Get a Lyr to go with them.  There,  I said it.  Twice.

I'd be interested in hearing more about them.

My comment was just a knee jerk opinion.

That's because I tend to be a jerk.

 

And don't think I don't lust for a sweet pair of those tubes.

post #5097 of 8735

Now if I lived in a cool old house, I could go up into my magic attic and tell my wife I found a pair.

Alas, this does not work in a ten year old home.

I wish I had money grow in tree darthsmile.gif so I can get Lyr.

Let me help you rationalize this.

 

Lyr:  $450

Valhalla $350

 

Difference:  $100

Estimated loss from selling used Valhalla $100

Total difference: $200

 

You were bidding on tubes at $120

Cost requiring rationalization:  $80

Sounds interesting, I need some time to sell the valhalla.  I can't just sell it right away...sad news for the valhalla, love this amp.frown.gif
