LIVE Lab Cam

[Michael Rothacher]

A new experiment in info-tainment!

I'll be turning on the cameras when I'm in the lab working/tinkering. So, when you get tired of watching your aquarium, you can tune-in and watch me get shocked and stuff. I'll stream it live on my YouTube channel. No format, no schedule (yet), no script, just relaxing audio fun. If you miss it live, you can always watch the archived videos. If I get really ambitious, I'll edit together an occasional best-of.

Why am I doing this? Who knows? I just like trying stuff and seeing what works. Hopefully, we'll both get something out of it.

You can stop by and chat (use the YouTube channel chat, and maybe I'll monitor this thread as well.) Use it as a chance to ask stuff you'd normally send me an email for, then everyone can benefit.

Starting this Saturday around 10:00 AM EST. Bring donuts. Link in my signature. Skype audiohobby.live

Some stuff I'd like to work on in upcoming weeks/months
This weekend:
500W bulb test
2SK180 - 193V loadline test
2SK60 stuff
Test new transistors
Buffer test

On-going:
P SIT
Work on VFET2 chassis
Work on chassis for NP's special gift
Circlotron revisit
Charity auction amps
OB speaker - 3-way B4 project

I'll request that there be no magic smoke.

Cheers,

[Michael Rothacher]

That's a tall order

Look forward all interesting themes i like it

2SK180 - 193V loadline test

182 could be fun too!

 

[Michael Rothacher]

I don't have any. Want to work something out?

All great stuff, very interesting.. I'll tune in.

Well,
sounds as if I will become your fan! Seriously, I'm really interested as I did some 140V loadline tests with the 2SK82 myself.
Really looking forward to this new experiment in info-tainment, Mike!

Hi Ulrich,

In this case the 193V is the Hammond inductor rather than a voltage amount.

I had someone ask in email about the 180 with that particular inductor.

 

[ui2]

Dear Michael,
a little low familiarity with the Hammond catalog plus a bit of wishful reading & here we are!
Funny.
But nevermind. I found it always very instructive to watch to your videos, so I'll follow.
Ulrich

 

[Michael Rothacher]

Great, see you then

A Circlotron with 2SK180 would be nice

 

[Michael Rothacher]

Indeed, but I think I've given them all away except for the pair that are in my SE amps.

If anyone out there has a stash, I'm sure I must have something you need somewhere in the lab.

Don't seem to be able to send you PM, so I sent you a mail

 

[Michael Rothacher]

Thanks Tim, I turned off PM, because I have tendency to lose track of them. I'm better with email

@ Michael Rothacher

Thanks so much always something to learn from Lab Cam
Very impressed because is not diy bench corner but potentialy
one amplifiers factory with all machines , tools and more.
Fantastic AudioHobby " Garden" with flipper pinball
+ 1 vote for circlotron topology amp explorations.
Happy Sunday Mike @ Diyers my kind regards.
Chris

 

[Michael Rothacher]

Thanks to those who tuned in. I've worked out a few bugs and things should keep improving.

What is the type of this new transistors to test ?
They are new old stock or new in your lab or new from Mouser or... ?
Greetings

 

[Michael Rothacher]

The new devices are MOSFETs. I want to test them before I mention part numbers, though, in case they don't pan out.

BTW. It looks like the SIT circlotron has already been covered here:

http://www.diyaudio.com/forums/solid-state/275329-sit-2sk82-circlotron-power-buffer.html

It's pretty much what I was going to do. It looks very nice and I wouldn't want to duplicate efforts. I have other circlotrons to explore anyway, so no worries. I also have some other SIT stuff in mind.

Yes i know this thread but i was thinking about 2SK180 circlotron...other SIT ?
Some with 2SJ28 or russian surprise , satellites , radars stuff ?
