Good!...i will like to see you work.

regards and thanks,

Carlos

 

[coolet]

the heasink dimensions I send to you is correct. It came from an old AC Frequency Drive.

 

[destroyer X]

Just for curiosity...do you know the previous equipment power?

the DC voltages it was using and fuses values?

or primary fuse value and AC mains voltage?

regards,

Carlos

 

[coolet]

it is 3.5kw using IGBT. no internal fuse rated at 380Vac 3 phase.

So. it seems i underestimate your heatsink...it may hold twice i said

This is good....will operate cool and confortable even in my country average temperature (29 degrées celsius).

Will be great in your place!....would be able to face full undistorted power, continuously, both channels driven and using 4 ohms loads...better than that ...only if i could have heatsinks alike yours!

Also will be able to have 5 channels attached to the heatsink.

regards,

Carlos

Return Soon

.... I will be back!

Best wishes for a short and easy time in Hospital, Carlos.

I think your first comment will suit, I forgot to mension that the heatsink is force ventilated by two small (6x6cm) 24 volts fan.

I do think i will be walking in the next day...so big positive energies will be

transmitted.

Brazilian forum guys promissed to concentrate 30 seconds of energy... directed to Brazil northeast..facing the northeast of brazil..watching it (there are deviations because poles in some cases..20 degrees errors because magnetic bending from North Europe to Brasil). in August 24, 2PM

I will stop to ask help...in that forum almost hundred said will do it...i could be electrified ...ahahahahah!

I am happy!... the biggest and golden best fat bugger dream will be realised folks... i will have permission...better..order!..to eat each 2 hours till feel satisfied... quantity is controled..there are maximum quantities of course....ahahahahahaha!....great that!...and even this way i will loose 140 pound in 7 monthes..then will reduce the loss ratio, because food will be more strong!

I cannot wait to have my Vanilla icecream! non fat one..sugarless of course.

The hospital is the Best..the Doctor is the teacher of the Brazilian teachers...the one have operated thousands..no death, no complains and no return... 12 years long doing it... the one is famous wide world.

What a fat bugger may want as a better dream coming true?.. eat all day loosing weigth!..this is a paradise!

Will pay anything..all covered by health insurance.. that cost 250 USD each month to my age.

Thank you Simon.

Carlos

Well...and have a fan?.. this is wonderfull.

Reduce it's speed using 7808 integrated step down voltage regulators..can enter with voltage till 25 volts DC i think...with 8 volts will be noiseless.

Good my friend..you will have a beautifull amplifier this way...very strong one!

regards,

Carlos

.............................................

I will order them to change the name in the hospital front (kidding) to Dx Headquarters..... the real thing is that this hospital belongs to my ex wife's cousin (reality)... so...there...i am the king! (truth)

Picture names are fake..of course.

As promise

here is the 5 watts vertical resistor

 

[coolet]

Horizontal Big 5 watts resistor (same PCB Layout)

 

[coolet]

TO220 case 20 watts 0r22 resistor which I have in my parts bin(same PCB layout)

 

[destroyer X]

Yes...i like it...very professional look..the heatsinking linking transistores

was interesting, also vertical power resistances ...in the reality, these resistances can be 1 to 2 watts without serious problems..but i like it... low heat with these resistances...looks good...layout is well made...good distance between lines.... you seems to know what you're doing.

I see..you are using what you have in your part's bin..... interesting that you found room for them this way.

Thank you as you have shared your nice work with us.

Congratulations!

regards,

Carlos

 

[coolet]

thanks carlos, I just love to make circuit.

 

[evette]

Dear Mr Carlos, I just wanted you to know i<ll be sending you all my postive energy that my little brain can muster up. In addition I will send you a Get Well Gift. So you can get back to work. God Bless

 

[destroyer X]

Enjoy and have fun Coolet.

Dear Evette...you are a very sweet person...i do appreciate you a lot...and i am sure you will be sending energies to me...you had not the need to say..i know that very well.

regards,

Carlos

[Pocoyo]

there is a bad connection with this hubby
if you didnt drink coffee & smoke cigar so you will eat a lot

good luck Carlos, wishes you All The Best

 

[nikcho]

Good luck with the operation, Carlos! You will have my energy as well. I hope everything goes as smooth as possible.

Hello Carlos

Good luck with your operation.
