Sorry for the delay. Been in video shoots the past two days.
I’ve gone through every type of tube imaginable and every combination. Here is what “I” think sounds the best.
V1 - NOS GE 6072a Five-Star V2 - JJ 12AY7 V3 - JJ 12BH7 V4 - JJ 12AY7 V5 - JJ 12BH7
Takeaways:
Regarding new tubes, JJs really sound nice to my ear. Especially the 12BH7 compared to Electro-Harmonix, which are grainy in the top end. The JJ 12AY7s have full range and nice clarity.
Using all NOS GE 6072s causes a bit too much midrange buildup. However, using one in the V1 position compliments the JJs so nicely. It sort of smooths out the top end ever so slightly. A nice combo.

Sold on this... now then . . . What do I sell to make room for one of these? You know me. I’ll trade a preamp for a nice original U47 any day!

Okay. Here are two samples: 1. Original file 2. Original file running through the EQ, but flat 2024, 04, 05, Professor Dan EQ SamplesThis is at pert near mastered volume. Peaks around -1 dB to -0.7 dB. In other words, it's pushing the gear. Curious to know everyone's thoughts.

Everything sounds so damn good Dan; it'd almost paralyse me in indecision. One thing - I would like to hear it in and out of circuit with no eq. Cheers, Ross Sure thing! Let me do that for you.

Thanks, all, for the kind words. Here is a video demonstrating the unit on a stereo mix. Also, anyone who wants to pre-order can do so here: professordanaudio.com/pro-audioI have a limited run of 8 units available at this time. They shouldn't last long.

That paper, which is far from a scientific peer-reviewed article, seems to be talking about high AC voltage in power inverters, which can cause premature deterioration of the capacitor.
All I know is these Wima caps don't sound "hazy" to me. And I've swapped out many types in this circuit ranging from NOS paper-in-oil to film and foil, ceramics, and mica.
Nevertheless, I'm always willing to learn something new, which is why I was curious about your reasoning. Thanks.

Nice. I like your resistor choices. Never been a big fan of wima caps in tube builds, but ok.
Any particular reason for not preferring Wima caps?

Howdy, friends.
i’ve been busy and scarce from the forum for a while. My apologies. But I wanted to share a sample of something I’ve been cooking up.

Howdy friends,
I’m on the lookout for a Neumann U47 swivel mount and cable. Holler at me if you have any leads.
Thanks!

My process, after editing and getting all the instruments EQed and compressed the way I want for best tone, is…
1. Fold my monitors down to mono. 2. Turn off the left speaker. 3. Automate all the levels throughout the song.
Check at around 85dB avg, and also much quieter too.
4. Bring everything back into stereo and enjoy.

I have a K87 capsule that needs a mic body. With or without amplifier. Let me know if you have something.

How does the Neumann MCM 114 compare to the DPA 4099. I used the DPA on acoustic guitar for a couple years with success and now need to buy a clip-on for my guitar.
Sonic comparison?
Durability?

I don't like the logo badge on the shock mount...

I must say, those RCA cleartop 12AU7s have incredible top end detail. Quite affordable too. If that's what you want.

Yes Dan, there’s no such thing as a $4000 U47 from a zero feedback seller 😂 Seriously though, you should be able to get your money back pretty easy from Reverb. I saw that one too and thought, “Man! What a sucker!” …fool me once.

Yeah....so.....
I just got burned on a Reverb.com purchase today. Looks like a fraudulent post.
Sucks.
