Default clepsidra....this is the one i like


Also i think the name is better than alfa numerical codes.

Clep...can mean Klepto..... from Kleptomaniac...those ones have the need to stole things....crazy to stole.

Sidra is a very nice beverage, a destiled made with apple and other fruits...have gaz and remember a sweet Champagne...and may mean different in other places too.

Well..having meaning, easier will be to enter the memory of folks.

Nice name..at least i have loved it.

Also BGTs ...those i have, the technologie is deeply dominated by me.... FETs have other biasing points.

regards,

Carlos

Default Having the same problems as Graham Maynard, Bora has health problems too.

He cannot construct...some of them were constructed by him, others by friends and there are schematics never constructed.

He has not too much time to follow the forum thread..also not too much time and health to go typing mails from constructors.

I think he will give some support, but people will need patience.

He gave a good support to Mr. Sakis Petropoulos, as i could read those support mails entirelly, during 2 monthes, many mails arrived and were answered...but...was not enougth to Mr. Sakis..he had some problems, as made some small modifications in the supply voltage and some accidents happened.

Bora could not stay with Sakis all time long, as he was to the hospital...and he is already there.

This way, a gap of time existed and Sakis was alone...i have helped a little..but not too much, and also not enougth for Sakis needs.

Sakis found something considered bugs in Bora's legend circuit..and this was something he conclude in his mind...i think was more a misunderstanding... a communication error than a real bug.

Bora can help..but there are some limits.... people that construct must have a very good experience related transistors voltages, currents, to dominate Ohms law, capacitors, biasing point, offsets, and understand how transistor and field effect transistor works.

Bora can help people, but he cannot teach the very basic of electronics, also the test needed and the test signals and practices normally used, all those things must be already known to avoid problems.

regards,

Carlos

It's too sad, let's hope that everything will be OK for him.

Anyway, that's a huge amount of ideas.From a first look, there are some very promising circuits and anybody could try by his own to build and test any of it. Besides, that's the meaning of "DIY". Thanks to Bora for his ideas and his kindness, and ofcourse thanks to you Carlos, for your valuable effort, for publishing them.

regards
Spiros

Default Thank you Spirtos... i see that Greek people has some connections with Bora.

This is nice...Sakis already made Bora's amplifier and you are tracking with interest..this is very good.

Greek people is very interesting people..i have to say that i like them.... we had dtrif too..but this one disappeared... a pitty.

I fell happy to cooperate with those designers, in special because i understand their needs...not only Bora, but also Graham, need some cooperation.

They have, both, ilnesses...different diseases that turns hard to them to construct amplifiers...and i think that Graham has worst conditions, as he has pains all day long...and cannot move his head as we can...so...to construct is a hell for him..he has to install boards fixed in the wall...and moving the arms will move the neck and pains will come....very hard.

Those folks needs cooperation, good will people, forum friends, nice folks, people that has heart and good understanding that we have to help one each other..that we are half of nothing when we are alone.

Graham needs people to construct and to test and to help him to debugg, to evaluate his schematics..to publish opinions to produce feedbacks to Graham, to compare, to write reviews and to have fun...as we have fun doing those things...also contribute for our forum..to be good, rich and having interesting reviews to read.

Bora is needing too...people to construct, to evaluate, to compare, to test, to debug and to give him feedback....he will give his best..but people understanding will be needed...he is beeing sick those days...the follow up...the over the shouder help...that teacher to go to the very basic knowledge of electronics cannot be supplied by him...he just...cannot.

Graham..this one is a heroe....try to imagine enormous pains inside your skull...not medicine can relief..he cannot move...imagine to sleep...if he can sleep...around the clock folks..and he keep a reasonable mood.... beeing patience..when bad educated people comes to attack him with bad words, unfair behavior...and he keep a reasonable mood...this is heroic folks.

Graham helps a lot of people in his family...even beeing this way..feeling this way...and he do not feel hate to all humanity..he loves birds and flowers...and having damn pains.

Graham problem has no cure..operations, sourgery, hospital, and doctors can kill him.

regards,

Carlos

Thanks for your kind words Carlos.You are right.
Life is so unfair sometimes....There is nothing more valuable than health, but usually we understand it only when we face a serious problem...
