decided to up my nerd cred, so I got my technicians license for amateur radio today. 2 tests to go.

My birthday

Ok

Thanks for the b’day wishes! There was beer and pizza. Sent from my iPhone using Tapatalk

More being grilled for, but I'll take it

Bought some steaks the other day. NY Strip and Ribeye. Cooked one of each tonight the Serious Eats way (cool side of grill covered, finish on hot.) Not bad. May try sous-vide with a grill finish for the others.

For consistency's sake I restricted Al's least favorite camper from posting for four years. Seemed like the right thing to do.

Not at the moment. I’m mostly just trying to get to local repeaters and maybe the space station.

Happy Birthday Jose! Nice ride!

If you use MLCC C0G/NP0 grade, I doubt the difference will be audible. Or, MLCC will be even better. At least amb votes for them: https://www.amb.org/forum/about-building-beta24-t3688-10.html?hilit=mica#p34356

Happy Birthday, Jose!

Happy birthday José!

Happy Birthday! Epic ride you did there.

Oh, sorry for missing it, Jose. Happy belated Birthday!!!

Happy Birthday Mike! It's crazy to think that some folks around here won't remember what an important member of the headphone community you are (and how important the Fl team is). Have an awesome holiday!

Little shit is living better than I am. That's a Tesla. "Orange Crush" Sunset at Windansea Beach in San Diego, California.

Thanks Lee for my 1965 Ford Falcon..

RIP Lee Iacocca.

Got my new i9 iMac installed, up and running. 8 core i9 processor with Radian Pro Vega 48, 512 ssd, 64 G ram (2 sticks so I can go up to 128 if I go crazy). My external drives are in a Blackmagic Multidock 2 (thunderbolt 2). A Caldigit TS2 for an extra Ethernet connection for my Metric Halo interface plus some of my numerous USB thingys. The clean install went pretty smoothly and I've got it down to just a few days of hell. So far the Logic Pro X benchmarks I've run show that it'll run twice as many virtual instrument tracks (122 vs 58) compared to my old girl (2012 Mac Pro 6 core). Running nice and cool (I only heard the fan once during some installs and it was barely audible). I absolutely love the 5k 27 inch but I've been using a dying 24 inch, old Asus ProArt for freakin ever!

No, Dusty, those are not the Moth night lights, those are Moth M-304-TL power amplifiers. Moth Audio web site (May 19, 2010): 35 watt single-ended class A1 no feedback interstage transformer coupled monaural amplifier. Specifications: Topology: One triode for voltage gain, transformer coupled to the output power triode. Only thermionic devices and magnetic circuits are used. No coupling capacitors and no feedback. The output power triode never leaves class A, operation and is used at half its rated plate dissipation for longer life. Tubes: Four 6D22S rectifier "Svetlana" (Russian) One 5Y3 rectifier "Sovtek" (Russian) One 5842Q voltage gain & driver "Sylvania" (USA) One 304TL output "Imac" (USA) Wiring: Hand wired point to point for all circuits. Cardas solder user throughout. Capacitors: Polypropylene in soybean oil for power supply circuits. Output Transformers: Custom manufactured for Moth Audio Corporation. User selectable: 2,4,8, & 16 Ohms. Connectors: Cardas rhodium plated RCA for unbalanced input, Neutrik gold plated XLR for balanced input. Silver-plated speaker connectors. Chassis: Zinc plated 18-gauge, cold rolled steel with a heavy wrinkle black powder coating. Polished and black anodized 3/16" thick aluminum top and bottom plates. Brass plaques are custom etched and filled. Indicator pins are 24K gold plated. Glass Bell Jars: .25" thick hand blown Pyrex with acid etched logo. Power Output: 45 watts, 5% THD @ 1kHz. Total Harmonic Distortion: Less than 1% 40 - 20 kHz @ 35watts. Power Supply: Low-flux leakage design using toroidal power transformers as well as toroidal inductors. Frequency Response: (-3dB Points) 10Hz - 40 kHz . Input Sensitivity: 1.5V for 35 watts out. Input Impedance: 100k ohms unbalanced. 600 ohms balanced. Power Requirements: 105 - 125 VAC 60Hz (210 - 250 VAC 50Hz.) 400 Watts. Dimensions: 20"H x 15.75" W x 23" L Weight: 75 Lbs. Warranty: All components carry a 3-year parts and labor warranty. Tubes carry the manufacturers' warranties.

The answer is always, collusion.

On high Z, the L2 has a Zout of something like 50 Ohms. The headphones have an impedance of 80 Ohms at 1KHz, but 300 Ohms at 50Hz. That means there is a voltage divider with the headphone Z and amp Z. So, if there is a 1V signal, at 1K about 38% (50/(50+80)) of that signal is lost to the amp's impedance, and the other 62% goes to the phones. So you are left with a 0.62V. At 50Hz, the amp is still 50 Ohms but the phones are 300 Ohms. That means they get 86% of the signal. That's nearly a 3dB boost at 50Hz. Hence too much bass.

The Bruins got beat at their own game.

This is a bummer, though another "he was still alive?" moment. João Gilberto, dead in his home in Rio de Janeiro at 88. https://www.spin.com/2019/07/joao-gilberto-bossa-nova-dead-at-88-obit/
