[tab30]

I get this Amplifier, but I know nothing about it.

I serached the e-net, but : nothing.

Knows somebody something about it ?

The used Devices are IRFP240, IRFP9140

Hi Andi

Nice picture, but the name and model of the amp might help😉

 

[tab30]

Look on the picture on the pcb (right side).

The descripition is cuted out.

 

[tab30]

I forget

I should adtitional say,

This amp seams to be an selfmade amplifier.


As you can see at the front, it looks not professionel.

Hmm, the quality of construction on the PCBs looks commercial to me, is there anything written on the front underneath that white plastic?

Nice looking amp....I think its a kit myself.....main question here ....Does it work>???....can you give us a pic of the back panel?....if you dont see a UL or CSA approval then you know its a home brew and the boards were bought....its a definate keeper though...who ever built it did a great Job!!!

text on the front

No, nothing as you can see.


Maybe the amp ant the black chassie dont belong together.

 

[JOE DIRT®]

that looks like the front?? ....I wanna see the back..LOL
The chassis looks custom formed by the way not CNC stamped like most commercial products....how I know is from the look of the radius on the bends...( you tend to know custom work after owning a fab shop for years)

Could be some manufacturers prototype?

 

[Christer]

Not that I think I will be able to help you, but if you tell us
where you got it from and what country you are in, perhaps
it can give somebody else a better clue to what it is.

Looks to me like a commercial amp put into a DIY case.
Tab30 is a German speaker....😉

Cheers,

Yeh, possibly, but what makes me think it is more than that is the way the vent holes in the bottom line up perfectly with the heatsink, and it's not as if the vent is central, like you would expect in a chassis not custom made for that amp

Pinkmouse I missed that...your right...the cabinet was punched out....but I had a quite alot of tooling for my Iron worker and could do notching and punching.....😕 ...I`m debating now also LOL

Ahh, the highly trained, eagle eyes of a moderator never fail😀

Very true...

I don't know why, but it has a look of Britishness about it. 😕

It seems to have good components too.

It seems to have good components too.

Except for those trimming pots, they look nasty.

 

[mdlover]

what is those black stuff inside the toroidal transformer mounting? some kind of epoxy?

The trafo?

Looks like (if I see things correctly. . . ) the primary side of the trafo has the colors white, black, brown and gray. Would that indicate the source or country of origin or at least source voltage?

it looks like the amp made by the Sonus Faber, but i am not sure, because i don't have its photo now.

this amp not like a kit or DIY amp, it should be a phototype...

 

[rwagter]

It indeed is the sonus faber musica, I think even in it's original box but without the wooden front.

Here's the pic (sorry only small one)

An externally hosted image should be here but it was not working when we last tested it.

And the mystery is solved.
