Great Circuit designs have been around for years, China has most dialed in, they invent nothing, they are now masters at not only copying, but improve Amp components when and where they can. These were purchased over five years ago, KT88 based and still running, the wifes mono blocks get pushed just as hard as my two channel rig, original tubes throughout and still going. These are from my guy on the Bay, "PrimeAmp" China invents nothing? Off the top of my head: Paper Printing Gunpowder The Compass Clock (i.e. not sundial) Bronze Iron Smelting Tea Silk Alcohol Porcelain Rockets They were inventing stuff while people in Europe were still wearing fur loincloth's and killing each other with sharpened sticks. Never under estimate your opponent!

Yes, he called 100 dB "Average Level" loud. But he called for very brief peaks of 115 dB "at your ears." Klipsch's notions of loud show up in many places. One is Dope from Hope, Vol 16, No 1, January 1977. The paper was written by Don Keele, then chief engineer at Klipsch. He writes that he is talking about Average Levels (not brief peaks). LOUD 90 to 100 dB VERY LOUD 105 to 110 dB TOO DAMN LOUD 115 dB The sheet says that to get 110 dB Average Level during loud passages in the reverberant field (rather than the anechoic chamber in which the sensitivity is measured) of a 3,000 cu ft room with peaks 10 dB over average a single Klipschorn would need a 20 watt amplifier. What you get with SPL meter readings depends on the settings you use. When I have used "C" weighting (nearly flat) and "Fast," so very brief peaks have a chance to show up, I have read 110 dB a few times, which probably means I would have been using 20 watts. Sure enough, my peak reading wattage read out on my old Yamaha read about 25 watts, which is close enough! OSHA's upper industrial tolerable limit is 115 dB sustained for 15 minutes, not brief peaks. Certain kinds of music (some Rock, Metal, Electronic) call for extra caution, because they can be generally loud for sustained periods, rather than having surges topped by brief peaks, like orchestral music does. With age comes wisdom. So much for 300 WPC monster Amps and TOTL Receivers. ... and Carver Amazings.

Done.

Added to my list - Thanks Joe.

^^^^ That advice I'm going to get from every single dealer I talk to.^^^^

Thanks, never even knew that NAD made separate DAC's I'll google them both.

If that ever happens here, it would be in place of the 'suggestions' I get from mine on turning down the volume, using headphones or selling some of that old tube junk and those huge ugly speakers. At that point its noise cancelling headphone time.

Cool! I have the EML mesh plate 45 and the EML Globe 45 (rather than risk shipping I picked up in person at tubesusa in NY when I worked on a job close to that area); however, I have not heard the EML solid plate 45. I have not done any comparisons between mesh and globe since I run them in different amps. Here is a picture of my mesh plates in my Electra-Fidelity silver 45 amp, but I can only find pictures of the underside of my Yamamoto A-08S and can't seem to find my pictures of the top side of the amp with the globes. Here are a couple of pictures of the underside of my Yamamoto A-08S amplifier that was a kit build. I've wanted to rewire it, but the guy I bought it from did not have the instructions or schematic and voltages and I have not been able to track any of this down. I suppose at some point I will take voltage measurements and just try to draw it out then rewire. . Very nice! I've not heard the EML mesh plates but I bet they sound great. I purchased the solid plate 45's without actually hearing them. When I found they beat the sound (to my ears) all of the NOS 45's and 2A3's I owned, I was impressed enough to save up for the Limited Edition 45 Globes. JAC shipped them to Canada in a huge box with both tubes suspended like they were the world's last fertile Dodo bird eggs. They arrived in perfect shape, as Canada Customs didn't 'inspect them'. (I had a camera come by mail once which was inspected by CC, which based on the condition of the inner box really mean't that some clumsy oaf ripped it open or played soccer with it as the ball for the entire week they kept it). I purchased EML's 80 Rectifier to replace the NOS 80 Globe I was using (from 1920's production) and I've been very happy with this tube as well.

Very nice!! Are these from the 'Wright' amp builder who lived in Washington State before passing away 5 or so years ago?

Lol! The pictures above I 'borrowed the link(s)' from the internet. Mine are pretty clean but not clearly visible or packed away. I also don't need some Klipsch Wit here accusing me of selling him something. I'm a good buyer, but bad seller.

SNIP: Do you actually have the Yamamoto A-08S or the Yamamoto A-08, since it appears you have not uploaded actual pictures of your own Yamamoto amp since the amp in the picture is an A-08S? It is indeed the later A-08S which uses the both the EML Solid Plate 45's and the EML Limited Edition Globe 45's and the EML 80 Rectifier tube shown above. The Globe 45's have been discontinued by EML (they were too fragile to ship safely, even in the giant padded box EML shipped them in). In any case, the Solid Plates version tubes actually sound better than the Globes in my Yamamoto Amp.

Thanks. The Leben is the best sounding EL-84/7189 tube amp of a number I've owned over the years. The best sounding amp (when matched) with my Klipsch Belle's is the Yamamoto.

A couple of my tube testers. Upper tester is an RCA WT-100A and should have come with a mule from the factory to move it around. The portable tester is a Tripplett 3444. It is a accurate tester which quickly allows you to test a variety of different tubes. The RCA is great for serially testing and matching large numbers of the same tube accurately and quickly.

My Leben CS300XS. NOS Mullard EL-84 tubes and NOS GE 5751 tubes. Puts out around 15 WPC. Name sounds German but this amp is actually made in Japan. The combination of the gold and silver face with ash reminds me of the Fisher and HH Scott amps and receivers of the early 1960's.

I'm also running the Opera 211/222 and Droplet 5.0 CDP combination in alteration with the Yamamoto Amp. Power tubes are circa 1927 RCA VT4-B's in the Monoblocks and Russian 6H30P-DR Super Tubes in the CDP.

Yamamoto A-08? Yes it been happily hooked up to my Belles for the last 700 hours (over 18 months or so).

My old Teak 4 channel (1/4 track) put hiss on the tape, as heard through JBLs, Klipsch, and Headphones. Although the electronics may not have been very good, it was checked out by Teak, and they said it was up to spec, and biased/EQd properly for the type of tape being used. I bought Dolby B, which resulted in a sign in my recording room that read "Beware of the Dolby." I went to DBX, which, with the Teak, pumped. My tech guy (rated "The best in the Bay Area by the Bay Guardian) said that it was because of irregularities in the frequency response (3 dB "Head Bumps") in the Teak that the DBX was sensitive to. I replaced the Teak with a 1/2 track Crown, and the hiss was much, much lower by ear -- still there, but not a problem. The Ampex professionals at SFSU also produced a bit of hiss, but, like the Crowns, no problem. On the rare occasions I used DBX with the Crowns, that worked fine, too. ^^^Teac?^^^ Technic's Eye Candy here: http://www.j-corder.com/Black_Magic.html

Current amp in place is a rebuilt Scott 222C but that may change at some point in the future. I already have both a GF DAC09 and DAC11. One hooked up in my main system (the 11) and the earlier 09 part of a home theater system (for digital inputs). I was thinking something more neutral sounding and newer without a tube in the DAC this time.

I was at a local bar with friends and family last night. Our 20 something waitress, nice looking girl with a deep nasal voice that would drive me to drink if I wasn't already drinking. A couple of beers later and it wasn't helping. One beer was too many, and a thousand never enough.

Need to look at adding another DAC into a secondary system that is strictly 2 channel. It's been some time since I last purchased a DAC. What is out there now for two listening mostly music some PC sourced (USB3), some digital. Some RCA inputs, and for sure balanced outputs to an older Scott tube amp? Budget: up to $700 but would prefer to spend less.

Did you bring this amp out of storage plug, hook it up and turn it on, or power it up slowly with a Variac?

Talking is one thing ('yes dear, yes dear, anything you say dear'). Having to actually listen to her has to be the difficult part. Noise cancelling headphones and a loud source is what I'd be looking for.

Now THAT's funny Between what he ate and what his wife has said I suspect its been over-flowing continually.
