Now that we are on a first name basis...
I try to avoid abreviatons unless I define them first as some folks just can't follow properly elsewise.
I assume PLA is the Palestine Liberation Army, MT is Buffalo's Mighty Taco, ER of course is Emergency Room.
Of course it is brilliant of you to realize Amazon is spying on you and your posts etc. So your use of these abreviatons allows to say things the machine spy's won't understand. If I decoded your message correctly you were sponsoring a peace conference in Buffalo. Unfortunately the spaghetti you served caused some food poisoning and sent folks to the hospital, dashing hope for good results as one of the three parties present had to drop out!
Of course the spying machine suggestion to serve raspberry pie instead of spaghetti is advice from the blue. Personally I don't like all the seeds.
I.s.i.b.y.c!

I was watching QI last night and the venom of the slow loris was mentioned. There was no one in the room except me, I started to google, entered "slow" and the first suggestion was slow loris, coincidence?
It still amuses me how bad google and amazon are at delivering adverts for things people actually want given all their talk of ML and AI. I almost enjoy trolling their search bots.
If I type 'kippers' will I get fish adverts? Watch this space...
Oh, oh!
The first pic can become a nice wall poster. Enjoy 🙂

(and now I have good evidence to set the charges 😀)
How am I supposed to look smart if I can't use abbreviations and acronyms? That's all I have going for me...😱
Ed, I know you know them, I elab for others...and apologize.
PLA is a kind of 3-D filament, some plastiky sounding chemistry name.
MT3 stands for morse taper 3, one of several sizes. My tailstock uses MT2, my drive end has an MT3, the Wire EDM (electric discharge machining) rotary head I am building uses a MT2 to hold the ER collets. The Extended Range (ER) collets will hold the axle of the clock or watch gear I am cutting with the EDM.
edit: watched a cool video yesterday on EDM, now I am seriously thinking of adding another axis so that I can cut bevels. Because the wire is .003 inches, the kerf will be small enough that I don't have to do any fancy math to compensate for tool radius on bevels.... Sigh, it never ends.
Try as I might, I can't for the life of me figure that out.
I didn't know that Youngwood vendor was partially owned by Mitsubishi, made the order a little more complicated.

Not talking (and that would be easy enough) but I've seen projects for a head-mounted display:

Hello all, some audio "news" here
DIY 250W/4ohm amplifier based on "blameless" topology, and measurements

I didn't, but it's basically a camera with various extensions setup for macro work with a LOT of LED lighting.
@PMA: Nice. Good to see some 'old school' stuff still performing well. And after all, not every amplifier needs to drive an arc welding set 😀
Thanks George!
Thanks, Bill. Still enough current there. I made a mistake during first turn on, however had 1.5ohm resistors in the PSU rails to reduce maximum current - and the voltage drop across them was 30V ....
Interestingly all the components have survived except for those test rail resistors 😀
If this is your 1st MC, welcome to the club! 🙂
I'd like to know more, who/where/how much and so on. For the longest time, I've been wondering what to do with a couple of true vintage Ortofon SPU/GT I still have. I once sent them to Ortofon to be re-tipped with elliptical styli: very bad idea! The tracking ability is horrible: only about a 3rd of my vinyl works, and the styli plow through the rest making heavy damage.
It's actually my 12th. But my first attempt to get a low mV low DCR cartridge. I get them rebuilt by a nice man in Vladivostok who can repair things no one else will touch.
Including buying the bust MC20, complete rebuilt and postage to and from the other side of the world was less than £300.

Thanks.
I've tried hi-output MC's before, from Denon & Dynavector, but I don't like them as much as I do the lo-output ones: the $200 Denon 103 for the "guts", and the $2K Dynavector Karat for the linearity. My latest purchase is the $300 103R, but I haven't listened to it yet.
I'd like to hear your listening impressions.

Give me a while. Takes me about a year to actually listen to a new cartridge with work and kids. It would be quicker for me to post it to you to try 🙂
That is a great build and report Pavel!
I see you are using REW for some of the tests; can you sweep and share the dummy load/speaker emulator for impedance and EPDR (Equivalent Peak Dissipation Resistance) as well? Richard Clark and I built large speaker dummy loads many years ago to test the Tecron 7782/Crown MT10,000 amplifiers. We saw some amplifier power levels (and protection operation) not predicted by the static impedance sweep of the loads. The relatively new capability of measuring EPDR in software is very interesting.
Thanks in advance...
Howie
p.s. EPDR was implemented in REW as of build 5.20 beta 46 of July 2020, so all new builds since then include it.

Hi Howard, thank you, you probably mean a kind of REW features that I have not tried yet. I posted the dummy load impedance plots and of course I have Microcap simulations. I will have a look at REW to find out which kind of measurement you mean.
