Inovative Or Not ????

[sakis]

I FIND IT ....very interesting to be able to consume 300w of power and be able to have an amplifier that produces 400w of sound ....

opinions please

i also find the """"transistors of the device """" very strange since i havent seen them in any amplifier before .... they look kinda big for transistors ...dont you think ????

Sakis,

Looks like he uses some hybrid amp modules. Those 'funny' transistors look like heatsinked TO220 or similar, although the ehatsinks in the two pics are different. The 300W mains power for 200W*2 seems indeed strange, but probably the 200W can only be delivered short term and not both channels at the same time, which is not unusual for this type of specs.
Otherwise to me it seems OK.

this is all a joke .... a greek joke i presume since its rather obvious that in the output stk circuits exist ....

i wonder what all these people that strugle to make amplifiers perfect and i belive that they manage really well ..... for the greek designer that discovered the stk chips in the 21 century .....

on the other hand i find the 2 ohm note a complete joke ....

it is amazing i belive and i find a total waist to use a sweet tube to drive an stk ....

i am breathless of the nerve of some people

Hi sakis,
They do that a lot to speakers...

(I find, in another note, the 'old' variable loudness on the home stereo 'new' line of YAMAHA AMPS (2 models) quite innovative.)

I guess, also, on this picture on the right (http://www.audiotechnologies.gr/index_files/Page507.htm), that they show a blind person writing (NPI).

Sakis,

there have been both commercial and DIY hybrid designs with valves and STK modules before.
Fortunately Sanyo stopped production of the STK4050V (and STK4048) biggy, afaik.

i actually called the guy pretenting to be a costumer .....

and here is what he said to me

----transfromers are 300w rms (?????) and can deliver 450 max
----these are not any stk .... it is a special kind of stk that they been looking for 20 years
---- it is not available in the open market ( thetype is a secret )
-----the particular stk features 4x250W transistors inside
----- and will also happily drive 2ohms loads
-----then again there is no chance that you blow this stk since it also features limiters inside

and if you do blow it after all cannot be replaced by anyone and you simply have to buy the all magic board from the magic company ....

where i come from we call this b*****eeeetttt

Aha, i already wondered why they bothered to treat the power amp modules with sandpaper to turn the STK**** number into a blurr.
But not the V mark.

(thanks for making me laugh on this boring tuesday)

[sakis]

yes jacco !!!! i also do enjoy a nice joke once in a while ....

but to enjoy would be better to do it with a birchi with some kip sate and some pinda sauce


( i presume that my dutch is terrible but the taste was so grate !!!!! ha ha ha )

Looks ike the producers found this thread? Your link at the top is gone.

[sakis]

with me

this was my opinion about the specific device ....i see nothing wrong with that

very often you hear things in the forum about this design or that design ....

no probs .... i have nothing against the designer ( personaly ) i would like though greek designers to be really inovative and use new techonolgy and most of everything to be honest with their costumers ...
