I bought a big fat repair bill for my headphone unit. It was my fault, so there is that. $400 (including $76 worth of shipping) is a lot of moola to put out, but in this particular case, I had no chance of repairing it myself. Both audio output boards were damaged and they are freaking SMD to boot. They would be that hard to remove (the boards themselves), but me and SMD aren't worth the hassle. Besides at that time I didn't know if the DAC or other circuits might have been affected.
Turned 69, couldn't carry my clubs and play golf too. Getting old sucks. 🙂
Some stuff from Chian:
Two pairs of simple 2.5" FR speakers (will have them in my synth rack, just because)
Some 20 20K potentiometers (for a matrix mixer, I was going for a 4x4, but 5x4 could be made as well)
A 130W mains tranny for a EL84PP
Two RC-6 IR remote controls for the CAnon EOS M2 I recently bought
Five mini toggle switches (for the matrix mixer)
A clip-on tuner for guitar/bass/ukulele
Two pairs (is that 4, or will I just get 2??) 30cm busks (some unfinished corset projects)
And a high power Hitachi vibra... 😳

Impulse buy…
Lately I can’t seem to resist 8” fullrange/widebands that I haven’t heard. This is the third pair in the last year!
Wharfendale 8” Super RS… New Old Stock…$125…🤷♂️

Picked up a JL Cooper CuePoint to run the Alesis HD24. Now I need an interface to make it work, as the CuePoint doesn't have the data card in it...
I bought a pair of Hypex FA253 three channel plate amps with built in DSP crossover / EQ. It is just great. Why did I wait so long? Hours and hours wasted. Yes that slender black box on the left replaced the passive crossover and amplifier to the right for my three way speaker build. With the Hypex filter design software in about 20 minutes I had greatly surpassed the performance I achieved with three revisions and 40 hours of design and construction of the passive crossover. Yes the Hypex with 250, 250 and 100 Watts of amplification actually cost less money than the passive solution with the amplifier shown, the wonderful Douglas Self Load Invariant design.
The Hypex is practically an integrated amplifier as it has balanced and unbalanced analog, balanced and unbalanced wired digital and Toslink optical inputs all selectable from the remote control along with three configurable presets and volume. I highly recommend getting the display, it acts as the remote receiver as well, so you can see what's what. Amps can be daisy chained together with a single RCA cable. Set one as master and as many as you like as followers. Each amp has configurable power limiting so the drunk guy at your party can't accidentally use that 100 W amp to blow your tweeter. (yeah, you might be that guy) Madisound has these in the USA.

As though the Beyer Dynamic DT770 were not good enough, I just had to buy the upgrade kit from Custom Cans in the UK. That will keep me busy. But no folks, I also figured that my Whammy HPA needs a Burson Audio v5i upgrade. No, there was nothing wrong with the sound of the 2134 op amp in there to begin with, but I was adding power LED anyway (yes, the blue one) and couldn't just screw the lid back on when that was complete.
Apparently some information has been dropped; I'd check first whether maybe it resurfaced on the artofelectronics web site before exchanging your copy.

(Indirect quote from a now defunct website:
"Some chapters from the 2nd edition are not in the 3rd one because otherwise the book would have become too heavy to carry around with you: Chapter 12 Electronic Construction Techniques, Chapter 13 High Frequency and High Speed Techniques, Chapter 14 Micropower Design, Chapter 15 Measurements and Signal Processing. The same is true for some of the information in others chapters. I guess everybody who knows the 2nd edition will find a few of his personal favorite pages missing. One example for this is the "quickie guide" on capacitors in chapter 1 - one page describing qualitatively the most important properties of every type. I was even more shocked when I discovered that the "Bad Circuits" had gone. Luckily, the authors say in the preface that both the "Circuit Ideas" and the "Bad Circuits" will re-appear on their artofelectronics website. The site is quite new, so at the moment (6th April 2015) there are only a few of the bad circuits present. Also useful (if you own the book) is the errata page."
Mixed electronic components for a Superpsych-lfo and an ADSR. Filled up my car (40 litres of standard gasoline).
Gulp... I saw those prices.
How do you plan on keeping them sharp?
We have a $45 sushi knife we bought at a local Japanese supermarket and all metal Santoku we got as a gift.
The sushi knife is a single bevel, and the Santoku is double bevel. Both sharpened at a 15 degree angle. Very sharp.
I'm thinking we need a Nakiri blade. Since we're gonna be in Kyoto this fall, we might buy it there.
We might also try again a Kyocera knife. We had one once, it was great, very direct hand feel when using it, but it chipped!
But honestly, those expensive Japanese blades, they scare me. One false move when sharpening them and you ruin them.... my not so expensive blades, with the electric sharpener -and its belts and guides- does a magnificent job.
But then, you got this...
Sight....
I actually owned the Whole Internet User's Guide and Catalog by Ed Krol, published in '92. Bought it new.... I threw it away... it's likely a great book for beginners too. Presents a much simple WWW. AOL didn't exist. No viruses, no phishing. ;-)
The Web v. Gopher
Krol compares the Web and Gopher, stating:The Web and Gopher: You may be asking yourself what is so great about this. After all, what we've done so far isn't all that different from what you can do with Gopher. The Web appears to have a subject-oriented flavor, which is an advantage, .....
ROTFLOL Remember Gopher, Finger... ? Those were such sweet times. Innocence abounded then. I had my Thanksgiving Turkey recipe published by Butterball.... in their original web site....
SPEAKING OF PURCHASING...
In '98 I called Audio Advisor inquiring about some product that they had on their Internet page, but not on their catalog. The sales guy told me "Oh, we don't pay much attention to the Internet, we use the catalog".... Well, the rest is history....
Also had Internetworking with TCP/IP by Comer... release 1.0. Got rid of it when I got the release 2 books. I think I kept the 3rd volume in release 1.0
Are the old books more worthwhile?
You mean the entire set of Motorola CPU32 microcontrollers, the DEC VAX series, the data books for all of those Fairchild, Motorola, etc... with their data sheets.... Heck, I could be rich if old books were worth much...
Anyhow I did buy a bunch of stuff, but the most notable is 11 gallons of 87 octane in LA County for $4.99 a gallon. What a complete rip off.

Definitely keep the VAX manuals. I'm keeping a VAX system CD-ROM, just in case. At least I think I do. It was still in my office before the most recent move.
Somebody must have written a VAX emulator for your smartphone?
Back on topic: I ordered some zero-drift op-amps from Digikey, to build a noise generator I probably don't need.
