Maybe not Speaker Porn these days, but back In the day these were pretty hawt. Altec Model 19. Woofer: 15” 416 , Mid/high compression driver: 802 , Sectoral horn: 811 Very efficient: rated 104dB @ 4 foot sensitivity. Sound great with single watt SETs, but will still take 175 watts continuous. Too large for my current living room, been stored in my garage for years. Fired them up today....my neighbors were not amused.

After endless tweaking, the dipoles were sounding truly great - super natural and lifelike, with midrange and highs to die for... But still, i wanted more dynamics, more punch, MORE POWER!!!11!! So this happened: still just trying out different crossover points and targets in AL, but so far it's quite fun! lots of energy and punch, and a surprisingly good phantom centre. gonna try out the waveguided RAAL tweeters as well, and see if it matches the dispersion of the tractrix 200, as i really loved them on the dipoles. (sorry for the lack of headphone posts, but my headphone life is quite dull at the moment)

Re-reading (for the first time in a loooong time) Asimov's Foundation trilogy. Three very slim books from the early 50's that left a lasting impact on sci fi.

You don´t know the power of the dark side!

I'm using Molex 0638111000 (Digikey WM9999-ND) for Molex KK connectors. Nice tool.

Barrel can be hit or miss from the couple that I have tried. So far the “hits” that I have tried are still not that amazing.

Nice! BTW, probably the reason the BH is running cooler is that you've got 70+ watts sitting outside the case (those 4 EL34s at 9 watts filament power plus 9 watts plate dissipation per tube).

don't know anything about wigle. barrell has made a decent name for itself as an independent, non-distilling producer - similar to the willetts and smooth amblers of the world. yes, they are expensive and you will never know the exact source. but everything is cask strength, non chill-filtered, and most seem to have a decent age (7-10 years even where they do a blend). i personally have passed on them at retail because they're not quite a good enough value compared to four roses private selections, elijah craig barrel proof, even newer stagg jr. batches. one other cool thing about barrell is they've done a few different tennessee whiskeys for single barrel bottlings (most likely sourced from george dickel) which is highly unique for an independent bottler and they've have started to bottle rye and rum, both of which i heard were decent.

Flythough of the Orion Nebula from JPL/NASA. Simulated of course, but pretty impressive.

In case anyone should want to know, I measured the power usage for the Carbon, Blue Hawaii and SRX-Plus. SRX-Plus (using BHUltraMini PSU @ 350V) = 53 Watts Carbon (using GRHV PSU @ 400V) = 92 Watts Blue Hawaii (using GRHV PSU @ 375V) = 140 Watts

It's probably more if you go on there as a company and make a thread that goes "HAI GUYS LOOK AT OUR WARES" . That may trigger Jude's advertising revenue spider sense. People who don't want to pay are supposed to at least pay basic attention to sockpuppet 101 and make an astroturfing thread.

Yes. The master calendar is an annual calendar, not a perpetual, though, right? Shouldn't be quite as expensive. Still expensive. Cartier watches usually get a decent discount at the AD. I bet you can pick one up for under $5k, in the summer.

Happy Birthday Mike -- Big Cheers...

I am not good at putting words to what I hear, but let me give it a try. This is on my SR-007 with blu-tak mod. The Carbon is more crisp, but more 'in my head' in terms of sound stage. The Blue Hawaii has more body and a noticeably wider sound stage. While the Carbon appears to highlight higher frequencies, I find that cymbals and the metallic 'sizzle' sound of a snare sound better on the BH than the Carbon. Backward from what I expected. The reason I tend to really like the BH is that it excels at warm and full, but does not sacrifice high frequencies and fast transients in any way. Its ability to do both so well is what struck me the most as I started to get used to it. I can make the BH sounds more like the Carbon and vice-versa by using frequency equalization in foobar player. So it appears much of the difference I hear is related to which frequencies each amp peaks on. It is also interesting that I was expecting the Blue Hawaii to sound more like the SRX-Plus since they are both tube amps. But I find the SRX is just as different from the BH as the BH is from the Carbon. 3 very different amps. With flat equalization, I tend to like the BH best right now. I listened to the BH for 1 hour, then the Carbon for 1 hr. Not scientific, but I just enjoyed the BH better. As JimL has said, it is always the new girl who gets the most attention, and perhaps that is what is going on here. After building the Carbon, I felt it was better than the SRX, but after a few weeks I found myself using both pretty much equally. I am very happy with these 3 amps and am indebted to this community for all the help in choosing and building them. I am also glad I have all 3 because they are all different and great in their own way. EDIT: FYI, my source is a Gungnir Multibit ('Gumby') using balanced out into both the Carbon and the BH. Now on to more listening.....

Happy Birthday!

Got the filaments down to exactly 6.0VAC using 0.3R 5W resistors. B+ and B- are both solid now as well. +375V and -378V. About 0.2 drift over 30 minutes of warm up then stays fixed after that. Still comparing to my SRX and Carbon, but the sound is certainly glorious! I know, pics or it didn't happen. So.... Above, you can see that in order to make this fit in a 300mm deep case, I had to create 2 layers of boards. PSUs on bottom, Amps on top, with about 30-40mm of overlap. There was actually plenty of clearance and I could have moved them to overlap even more if needed. I was able to leave enough room in front for the power switch and future quad pot when it arrives. Please don't give me too much crap for the messy wiring. I plan to take it apart next week to add the quad pot and clean up the internal build a bit. I just wanted to prove to myself that it would fit! Also, notice that I am using the 755-SCT2H12NZGC11 as a replacement for the C2M1000170D for the PSUs. It appears to work just fine and runs cool. So we do appear to have a backup device for when the C2M1000170D SiC is out of stock. Also, in the front middle (under the mess of wires) is a timer delay for the CPC1117 HV delay turn on, as referenced earlier in this thread. I have it set for 60 seconds. Above with the tube cages. I have not install yet, but just wanted to see how they will look. That will be next week... And finally, sharing some room with my Carbon. Not pictured are my SRX builds (one mine, one my son's). BTW, so far, the BH runs cooler (both case temp and silicon temps) than my Carbon. Both running at 20ma.

Debbie took me out for dinner at Maple Tree Inn, one of the best Cajun places in Chicagoland. Started with 6 oysters 2x2x2 - 2 Rockefeller, 2 Bienville and 2 Deviled. Then 6 grilled oysters. Then southern fried catfish with dirty rice for main. Debbie’s BBQ shrimp with cheesy grits. A wonderful dinner. Sent from my iPhone using Tapatalk

Yeah I ended up spending double what I planned on. It seemed to fit and sound better than other guitars in the same range. Now if I can just build up some callouses. Ouch!

I picked up a new one.

Starting book 3 in the broken earth series

To set the mood properly for Blade Runner 2049, I've both watched Blade Runner from 1982 and re-read Philip K. Dick's "Do Androids Dream of Electric Sheep?". Had A BLAST.

I like the CFA2 so much I want to give it a separate PSU to move the transformer away from the amp circuit. The PSU chassis came in a few days ago. Still debating if to go dual-mono with 2 GRLV.

nope and nope..

Dolores O’Riordan gone at just 46, ridiculous. [emoji20]
