And...done! 30 minutes from opening the door. Thanks to G-Man and T-Money (sounds like a super hero duo) for the extremely accurate information and advice.

This weekend's Grand Prix junior event. For those of you who have never met Lance, he is the one dressed in white.

filed our taxes. i never imagined a scenario where the my tax-plagued state of Illinois would give me back more money than federal. lol.

Arrived 35 minutes before opening and I'm 10th in line...

Different 121r and 1k trimmer in parallel. Ok, it's no nice but we haven't space on the PCB.

Fuck the Trump "tax cut". That is all.

Apple refreshed the iMac series and it includes an 8 core i9 version with turbo boost up to 5Ghz! Thunderbolt 3, Radian 580, upgradeable ram and 4 or 5k 27inch screens. Gotta say I'm tempted to finally retire my cheese grater! I guess my only "if" is how many years the monitor will last or stay current? But for someone who was going to pull the trigger on a new monitor (like today) it stopped me in my tracks.

Hi, I didn't have a reference per se. My main goal was to improve on the Low-Frequency extension compared to most STAX out there and we achieved that. Here are the graphs vs the 009. I wouldn't get into my subjective opinions but I've had two people, one 007 MK1 and MKII owner come and place an order on the spot and another 009 owner who also couldn't tell apart the 009 from the RR1 apart from the LF response being more extended on the RR1. Anyway, here is the link with the Measurements (I have an upload limit here) - https://www.dropbox.com/sh/3rev8hq54sd3feu/AACb7Zs1DFcKZFYhs3co7Ecta?dl=0

This thread is awesome! I begin my spring grilling training this weekend though I must say I am a bit intimidated by you guys..

@Hopstretch and @morphsci - the Google suggests that we should be watching Netflix's, Love Death and Robots.

Agreed!

Have been having some offline discussions with JoaMat and Jose regarding the possibility of trimming the offset if desired. JoaMat came up with the idea of trimming the 100R resistors in series between the KSC2752 emitters and B-. He modeled it in a LT Spice model and I decided to give it a try. With my amp running at 14mA bias current, without this mod all the DC offset was between + 9VDC to + 4 VDC and balance was under 6VDC and I consider it totally fine. This exercise was more experimental and to satisfy the OCD part of me. I put a 50R resistor and 100R trimmer in series and adjust the sum to 90R based on JoMat's calculation. It can certainly be done with a single 150R trimmer, a fixed resistor in series with a trimmer is to protect against the small odd should a trimmer fails. I stopped making further adjustment once I got all the offset within 0.5VDC and balance within 0.2VDC. A few things to observe: 1. Turning one phase DC offset lower raises the offset in the opposite phase slightly. This gets a little tricky trying to zero out offset of both phases at the same time. 2. The bias current raises slightly as I adjust down the offset. In my case, the resulting increase in bias current was about 0.7mA. This matches what JoaMat saw in his LT Spice model. 3. The final resistance on all 4 "combo trimmers" fall between 86R - 90R. Take this as a reference only as this will vary from amp to amp and dependent on the bias current setting. I listened to the amp both before and after adjustment and frankly I could not detect a difference.

I got kitteh litteh in my ear.
