What about these?
Click to expand...

I can't find much on AMC.
The Good Points (from the listing)
They are 6922 valves.  A higher Quality.
They cost $52 a pair.
Couple things I don't like.
The listing says CCa.  Unless these are German made.  Siemans.  The they ain't CCa
It looks like the seller put every conceivable  tube designation in the listing.
They are from the 1980's  I think you can find some late 60's for $65 - $70  Bugle Boy's or Orange Globes come to mind.
 
Again,  I haven't heard he-500's so I can't give you an opinion.

Cool thank you.   What do you think of these in terms of SQ?   Are they good?   I've got a matched pair of Amperex JAN 7308s and a matched pair of Telefunken E88CC and the stock tubes already, just want to try some other options.

I've found them to sound really good; a great bottom end and mid-range with a slight emphasis on treble (almost but not quite sibilant)  but the treble does smooth out after a while (although the emphasis remains...at least it does to me and my LCD-2s).
 
It's not as wide and musical a soundstage as the Stuttgart Lorenz, but they do have a good sound.
 
As I was typing this, the TubeMonger guys just e-mailed me this and I want to share (Thanks Guys!):
 
Some notes from the recent posts on the board
 
"Following are Tungsram tubes at a very good price. Tungsram E88CC is a desirable tube that is often overlooked.

About Ei Yugo tubes with Lorenz label - it is a bit misleading to call these Lorenz. These are Yugo Ei Nish Plant tubes and have nothing in common with Lorenz except for the label. Almost all of these originated from the same military auction in Germany. Go for the cheapest source and you will save money. 
 
All of the Ei Yugos should look like this. 
Ei PCC88 (NOT Current Prod) - 1968 MPs MINT NOS Lorenz SEL Label with Bundeswehr Falcon Logo Same Date Batch 08K - Nish Yugoslavia
http://www.tubemonger.com/ProductDetails.asp?ProductCode=801 - We are out of stock."
 
 
I have to hand it to the guys at TubeMonger...they have some of the best service and support I've ever seen!
 
Cheers!

Has anyone bought from tubemonger? Are they reliable? I usually buy everything from Upscale, but tubemonger has a decent deal on a matched pair of tungsram e88cc, however this quote from their website was not particularly reassuring: NOTE: Tube boxes are not original. Our source from Hungary had re-packaged these from military bulk boxes to what seems like recently printed boxes.

Not to imply any funny business on their behalf but my Spidey sense is tingling in relation to their supplier.

Tubemonger is just as reliable as Upscale.

OK cool.

Yet another stupid question. At this time I have two DACs, an ODAC and Aune T1 DAC/amp. The T1 is a tube buffer USB DAC, it also uses 6dj8 tubes (single tube). My question is, if I want to us the T1, should I match the buffer tube to the gain stage tube in the Lyr for best results or does it really not matter?

I bought the ODAC based on reviews and quality, and frankly I don't want to spend another 80 - 200 dollars on a third tube. I like the idea of lots of tubes and all but my wallet has limits.

TubeMonger was the main source of the Lorenz Stuttgart tubes that many of us bought.  I bought at least half of my tubes from them (close to $1000-1200 worth).  They do use new boxes but they write the test scores of each tube on the box so you know you are getting tested and matched tubes.  They are an excellent source of tubes.  If I had any complaint, it's that they ran out of the Lorenz tubes...

Don't get the wrong impressions. Even when the Lorenz was available it was unobtanium.

I got glass that hasn't been heated yet and another set on the way.

I haven't had overall tube noise.
I had one microphonic set of USN-CEP's and a single fuzzy Bugle Boy.
eMail Schit.
Also might want to check it on a different power circuit with nothing else running on that breaker.
 
If I turn it off with the cans plugged in I'll hear the relay cut, but it's harmless.
There is a circuit protection.
 
I just follow a ritual of turning the volume all off, pulling the plug, and turning it off.
