Default I reffered your schematic... dear Carlos

and the same voltage (+/- 62 DC)... i just wanted to design the PCB for folks who are willing to construct that.. I too want to construct and feel the super sounds of Dx triamp. but before that i have to complete Dx standard and DHR turbo housings and speaker enclosures for them.

Since I dont have any technical knowledge to design amps, I decided to draw PCBs. At least I can contribute to Dx corporation in that way.

Dear uncle Charly, if you can post me a universal schematic for both triamp bass unit for 62V and the Dx standard 62V so we can use one PCB layout with different component values for both (If it is possible only). By the way Alex mm is the no 1 designer in Dx corporation(IMO). His DHR turbo PCB is very nice! I cannot ever beat him hehehehe...

Default Not needed...the Dx Amplifier has already a board.

If you want to make the bass unit pcboard..well, it is up to you.

Dx Corporation thank you by the confidence into our products.... all them free, dedicated to provide you nice musical moments in your life.

I could not recognize your flag.... what is your country Lycanlk.... in the past we could rigth click and have that information about the flag country...i could not find that anymore.... there's no town, nothing written...what to you think to visit your profile and provide us some more news about you?

Carlos

Default Here you have the resistances bigger than 1/4 watt

Others you can use 1/4 watt (250 miliwatts) or bigger if you want.

Into the schematic the special ones..the ones to install higher wattage compared to the standard 1/4 watt normally used in audio amplifiers.... so...other than 1/4 watt resistances are marked.

regards,

Carlos

Default My country is Sri Lanka...

Colombo is our capital city. i'm living close to the capital. Its an island in the Indian ocean (a big island.. hehehehe..). you can find more by googling it. because my english is not good to explain more..

I only know about Greg Erskine PCB for Dx amp which is designed for +/-35V. Its a good work. Can we use the same board when we supply +/-62 volts or do we already have another board to fit components when the supply is +/- 62 volts? (if so... I have missed that, sorry)

Anyways I can try triamp bass unit followed by your schematic or someone else will try.. ahahahaha... never mind.. ill be happy... !

thank you !

Default Thank you for the marked schematic..

Siri and Sri both are accepted by my mother language but slightly different meaning for both according to my language skills. SINHALA which is not a very famous language. But I would say its a very rich and difficult language especially when it comes to literature. Alphabet has more than 50 letters.. hahahaha..

Default You are welcome Lycanlk.

Dx Corporation has one subsidiary producing "active filters"...Town is Belém, State of Pará....exactly in the middle of the Amazon jungle, having the Amazon river flowing and producing beaches there..the subsidiary company is called "Marcisium Laboratories" and the active filter, made to the Dx TriAmp is beeing prepared.

Soon you gonna have news about.

Picture shows the bass unit prototype.

Carlos

Default Marcisio, from "Marcisium Laboratories" works as a computer programmer

But he is a figther too... thailand martial arts.

His active circuit to be applied into the Dx TriAmp will "smash" the competition, the same way he use to smash people while figthing..he is a Champion!

Marcisio is at rigth side.

Carlos

Default Here you have the schematic tested by Marcisium Laboratories

Soon he will send me, by mail, boards to be assembled and tested.

This way, amplifiers will not have input filters and modifications will be posted latter..the special modifications for the bass Amp, the midrange Amp and the treble Amp to match the active input filter.

The circuit has buffers to match impedance and to increase level a little bit.

regards,

Carlos
