Hi, Carlos,

I think someone like Steven still enjoys analog cct Read his footage of "Dodo's faith....."

[destroyer X]

this is good, despite of enormous know how, did not loose passion for those things.

You know, when things turns obligation, normally our interest reduce.

Working with audio...well....may be a little boering.

Beeing a hobby is very nice...but transistors all day may be terrible.

Thanks Lumanauw

regards,

Carlos

Papers with S. Pookaiyaudom as one of the authors that were published
in the later part of the 70's uses the topology.

I think Brett Wilson referred to the cross topology as the Pookaiyaudom
quad (or something like that) in the early 80's in one of his papers???

Hi Tom,

Thanks for your info!
Do you have any paper in electronic format like pdf or so in the subject you could e-mail me?

Carlos,

I agree with you, sometimes it's better to not know too much, it's much more fun then!

Cheers Michael

I already sent him all the positive energies i could....and will keeping thinking on him along this day.

Bora, alike all of us, loves his father, and living a bad moment, reason why he is not here with us.

regards,

Carlos

The papers I have are xerox copies from journals I copied back in
1990. I have about five references. The copies are in good shape. The papers are short. If you want I can scan them and e-mail them to you.
I'll have to experiment what format works best ( jpg, pdf or tiff??).

I can give you the references if you have access to a university library also.

Carlos,

thank you for telling us about Bora, I started to wonder where our friend was. Our thoughts is with him!

Tom,

if it's not too much job scanning those pages, please do so, I guess pdf is the favourable choice.
Unfortunately I don't have any close access to university library, but please give the refferences.

Many thanks in advance Tom,

Michael

Ultima Thule,

No problem, I will scan and convert them in the next few days.
I've been wasting to much time playing Doom anyway.

I just returned from a course I attended for a week, a follow up course on Marketing. I enjoyed it a lot. It's not about electronics, nor about audio, but still I liked it.

Carlos, don't be afraid, I still have an affection for analog electronics. Although I hardly do anything with it professionally, it continues to be a hobby of mine, and I enjoy to find simple ways to realize a certain function.

Anyway, it was never my intention to belittle Bora's Delta amplifier, calling it nothing special. I just meant that the design was straightforward. It looks like a lot of attention to detail went into this amplifier.

Regards,

Steven

BTW Tom, could you send me a copy of your scans too?
