Mark,

I recently saw a a pair of the Seimens CCA's for $225.00. They are getting rarer. Kind of the same principle as buying land -- there's not going to be any more of it.

What do you mean "run of the mill 6922's"?

I was quoting MarkL when he made a comment on the CCa vs other 6922s and he stated:
Quote:
From what I gather, the CCa are no different physically from the "run of the mill" tubes, but they tested best out of all the tubes that came off the line at that time. Is this correct tube Gods?

He is correct in that they are not in any way different, it is just that these are supposed to be the tubes that tested with the highest quality of all the 6922 tubes they produces. Something like only 10-15% of all the 6922s produced were labeled CCa.

I'm considering using something else and buying some more CCa's to sit on and wait until MarkL runs the supply down a little lower before selling them to Mark for a huge profit once he's addicted to the awesome sounds they produce!!!! MUAHAHAHA

Amen. That about sums it up.

if you live near Sac, or can get out to Sac around Christmas I'll be happy to lend you a set of CCa's!!
I'm in the Bay Area of California so probably too far from Sacramento to make it worth-while. Thanks for the offer, that's very generous. I am now going to PM you to find out where you got those tubes for $150.

To make sure that you get the good CCa tubes, if'n yuz interested, make sure to compare them to this photo:

PHOTO OF EARLY AND LATE CCAs


I would send in a photo of mine but they are on their way to get cryo treated!!! Which, I highly recommend as this toughens metal and makes it last longer!! Hey, if I spend $300 on four tubes and can squeeze another couple of hundred hours out of them, I'm gonna do it!!!

Man, I sur ehope this guy is just clueless about tubes cause if he's not it's a scam. Many people think that just because a CCa is a type of 6922, that therefore ANY 6992 is a CCa. This guy lists his E88CC Siemens as a CCa, even lists in his auction "same specs as CCa" but it is, in fact, NOT a CCa!!! Misleading!! Definitely. On purpose? Don't know and will give the benefit of the doubt.

EBAY LINK!

Can you describe the particulars of the Sylvania tube?? Type/shaped getter? Color of label? JAN or other labeling? Etc. etc. etc. Sometimes it is SO difficult to get the same tube as someone else without TONS of info. I find myself emailing people on eBay just to ask these types of questions to make sure I get what I want.
The Sylvania tubes I've been using for the past 3 months or so are being sold continually by a guy on ebay. Do a search for "sylvania 6922" and you'll likely find a Dutch auction priced at $6.49/tube. He must have a huge stock because he lists up to 30 each week.

I've never heard a Sylvania 7308, but the 6922s are the best tubes I've tried in my system, beating by a large margin a few types of Amperex tubes and a pair of JJs.

If you're itching for some tube-rolling, it's worth a shot. Figure less than $20 to get a pair delivered.

You think that's bad? In a set of used tubes I bought, I found ONE perfect condition CCa. Paid about $5 for it...but I've never found a mate for it, dammit.

Sweet!! Yep, just like you said this guy's got 30 more just sitting there to be bought and rolled into a sweet sounding headamp, now to be sweeter with the addition of a number of these tubes!!

Thanks DVR!!!!!

Almost forgot, at the whpooing price of less than $7 per tube, if you can live with the sound and really like it, why buy anything else!! I might pick up about 12 of these and get them cryo treated to see how they sound afterwards!!! At that price, what have I got to lose???

as a generalization 7308s sound best with the amp. a run down of what i consider the best with it:

Expensive:

Mullard 7308 Gold Pin - brings some much needed body to the amp, a texture rich tube without glares in frequency response. lots of air.

Phillips "Amperex Factory" (early 60s vintage) e88cc - a flat sounding tube that brings some texture and clearer definition. great bass.

Amperex Bugle Boys - Hirsch sent a pair that he had tested for bkelly, ******* they have tons of body if a bit sloppy bass wise. in my experience they turn microphonic in a hurry but Hirsch tells me these test excellent. the Melos is the only component they've been this good with.

Cheap:

Sylvannia 7308 - Soft tube that helps the upper frequency hardness of a stock SHA-1.

Old Stock Russians - smooth on top (which once again helps with the upper frequency glare), good bass, some body.

JJ Teslas suck the body out of the music. Wimpy tube (to these ears).

I hate to ask as it is probably quite obvious, but what is the difference between all these nomenclature of Melos stuff?? There is: SHA-1, Gold, Gold Reference, Maestro, ad nausium. I know that an SHA-1 is different from the rest, I think??, but what do the rest of these names mean?? Different parts, different models altogether, different upgrade paths??

I just bought a Melos Gold Reference, and am not sure exactly what it is compared to all the rest, so tube purchasing might be a little difficult!! It sounds like Carlo is referring to an SHA-1 when he posted above, so I'm confused as to whether these tubes will sound so hot in my new rig??

Any and all help would be appreciated!!! Especially before I go and spend a bunch of money on some more tubes.

Serving,

Melos Amps and what makes them different

the comments about the cheap tubes were in regards to their ability to act as a stop gap for the SHA-1, the expensive tubes are in regards to the best on all the Melos incarnations I've used.

best,
carlo.

Carlo,

Thanks again!! I'll keep that in mind when looking on eBay for tubes. Seems some guy is selling 32 Amperex BBs for $15 each. The only problem is that he is selling the whole lot for a whopping $480!!!!!

I reread that thread you posted, it really helped clear things up!! I was confused as to whether or not there was 1, 2, 3 or more different products, or were they all varations of the same product.

Well, i've got a few cents to contribute to this thread. I was using a set of JJ tesla, but the left tube started getting noisy, so i picked up a set of Mullard gold pins and some BB's.

Overall, the gold pins take the elements that most people seem to like about the JJ's, and takes them to the next level. They're not very warm, and extremely transparent and detailed. They almost sound akin to solid state, but with a tiny bit of magic thrown into the musical loop that brings the music alive.

The BB's are incredably tubey and warm, something that i find entertaining for novelty use, but they just don't have any soul to them. They're fun, but nothing incredable, IMO.

Man, when these mullards die, it's gonna be hella hard to get another set, i got an amazing deal on these (50 bucks for the pair)
