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.
is this right tube for lyr?
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.
I think they would be wasted on a Valhalla.
They may shine in a Lyr.
Save the $500. Buy the Lyr.
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
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.
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.
Let me help you rationalize this.
Estimated loss from selling used Valhalla $100
Total difference: $200
You were bidding on tubes at $120
Cost requiring rationalization: $80
