No more aching back

It's kinda funny though.

I used to feel a bit ignorant, for not paying much attention to the commercial offerings.

Now it all of a sudden seem to be cool to be ignorant 😀

It's been a while since I made that high dollar comparison. I think everyone has to do it at least once--kind of like sex. 😉

 

[DaveM]

If it was really like sex, wouldn't we be doing it as often as possible?

Overindulgent, uncouth... (my middle name).

I thought I'd better remain silent, for the sake of the elderly around here 😀

We use something similar at work to lift 3-phase 10KW power
supplies.

That's no way to talk about Choky!

 

[Magura]

Choky?

As I recall, he is a couple of years younger than somebody else.

....and no, I also don't refer to Nelson.

Ahh, but once you're over 50... watch out for that banana peel. In other words, we're all in the same boat.

So, how old are you--you whipper-snapper? 😉

 

[Magura]

Old enough to be your son

Or in plain numbers, 34 as of last Sunday.

for mighty ZM - just turn around numbers of that kid

OK - take one year down ....



( last Mai I had 15 )

I would have sworn that I was going to be the child of the bunch, but I guess that prize goes to Magura. I turned 36 about 3 weeks ago.

 

[Magura]

That feeling is easy to get in this hobby.
In our age, we have like 90% chance to be right, when assuming that the others are older.

I appreciate your sensitivity in so doing, thank you.


As for banana skins, I have had a serious Achilles tendon rip, severe gout , and as they say these things come in threes a kindly builder let a 11' scaffold steel pole slide and hit me on the top of the head....never realized I had so much blood, or how long concussion hangs around.

pre V day! ! 😀

 

[carpenter]

Ouch... You poor fellow. I notice that as I get older, accidents are lurking everywhere.

Presently, I'm at the coast chatting with you guys on my iPhone. This beats the science fiction I used to read. Wow.

Hi all,

I'm back home, hooked up a populated 3rd stage and turned on the juice (with a variac of course).

Very pretty sounding. My first stage is a jfet differential, not the ZVN3310 depicted in the schematic, above.

I feared it wouldn't be bright enough, what with there being two stages of jfets. It seems I was wrong--the amp sounds amazing. I mean, REALLY amazing! I haven't worked the voltage past 11.5v, but when I have more time and can take some measurements, I'll see about getting her up to 19 volts. I notice that increasing the voltage from 10v to 11.5v makes a world of difference. It's possible that the final 7.5 volts will offer improvement as well.

Shooting for 1 excellent watt and loving it... 😎

 

[carpenter]

Amazing efficiency. I've been listening for an hour. Look at the size of these heat sinks--the larger mosfet heat sinks are only 43C. The LU1014D heat sinks are 24C. I'm filling the lab with plenty of music. It's like heaven...

My golden ears wife says this is the best I've come up with so far...

 

[Magura]

That's not too bad John, congratulations.


Magura 🙂


...but do send your wife for a checkup of her hearing 😀
