Destroyer x Amplifier...Dx amp...my amplifier

[destroyer X]

This one will substitute the Canon while under corrective maintenance (repairs).

have already started, near to finish, the High Resolution II

I will post some images.

Dx amplifier is an amplifier of heroic people.... heroes use to be interested ... do not know the reason the unit atract those special folks.

Rabbitz had problems into his fingers...some nerves...electrical problem into the fingers.... to move is a little bit difficult... sensor are not giving him too much feedback.... even this way the guy have constructed.

I have to thank you very much because your effort dear Rabbitz..also by the pictures you sent.

Those Aussies..... always lovely people.... this is very interesting how they can be kind with us.

I have enormous respect by him.... i would like to be possible to travel to Australia, to have a coffee with Rabbitz, also with Hugh Dean, Thorton, Greg Erskine, Alex Kethel, Anthony Holton, harry3, billabong and many others that i will not write here because the list will be too much long.

You, dear Aussie fellow, consider yourself included into the list..you are all excelent folks.

I would be happy to have a beer with those folks.... really i would be happy.... we never know folks.... i have visited and lived in Japan...why not in Australia?

He has expertise into those things.... he is an living Encyclopedia about that.

He shoud write a book and fast...about that.

he use the hardware.. he is not lemmon fruit simulator designer... he use to cut his hands, a real Do it Yourself man.... macho...male!.... those guys that decide to construct a swiming pool and put his arms and hands on work and produce an excelent job.

His speakers, really constructed by hand, are excelent and beautifully finished.... art work.

The knowledge about those things are enormous... a gift to us if he decide to write a book with images about that.

Evaluating by the image...you see his choice...the best possible friend we can have.

After the old girl passed away a few years ago, I have a new special friend.

[destroyer X]

Well.... this is my imagination only.

This one has a sad expression.... was he sick when the picture was made?

made special for Dudainc, that had bougth a lot of good PNP Sankens at E bay.

The the output transistor quantity may depend from the speaker impedance choice.... around 6 each rail to 4 ohms and 75 volts.

Power will go around 450 watts RMS over 4 ohms...undistorted, unclipped power....continuous power.

More than half of that will be the 8 ohms power.... and 3 output transistors to each rail may work fine.

Transistor selection must be carefull...because the supply voltage is very high.... 2SC4793 and complementary may fit to drivers, to VAS and also can be used as VBE multiplier...the BD139 will work into the VBE multiplier too...voltage there is very small.

The input choice also will need some care.... 2N5551 and 2N5401 may work fine...but will be better to select bigger voltage units.... those ones are very near the rail to rail voltage...their limit is 150 volts...so....may be not perfect....we gonna have half rail there..but even this way not really good and safe...also more linear if you choice bigger voltage units...alike 200 volts from colector to emitter as maximum allowable voltage.

This is an untested amplifier.... for sub woofer purposes.... output is loaded by the zobel..... also the feedback cuts frequency not so high.... the input capacitor can be very increased..the RF filter can be increased too.

Untested...but will work for sure..... made for Dudainc...and other folks that have a lot of PNP somewhere into the junk box.
