Gamut D200 clone !!!

[ANALOG GUY]

Does anybody interested this amp.
I have just seen boards of them on my DIY market but they don't have a schematic

If I have an opinion I'll photograph them for compare with original Gamut D200

I belive that Gamut power amps employs custom output devices.

custom?

I've been told they are exactly the same as in some welding- machine...(can't remember name).

Sorry for my missing word ToT

I'll wrote opportunity not opinion.
Gamut used power module mosfet with PWM technology.
I quite new about solidstate but I can find details of them soon.

When I modified GAMUT D200 !!!

I got this GAMUT D200 from secondhand market 2000USD, it's too complexity schematic !!!

2SK389BL for convert balanced input to single ended input, super mosfet quasi complementary output !!! and ...

Thanks

RIFA capacitor

It used computer grade RIFA capacitor and bicap with 0.22uF Vishay.

Completely module

D200 module with protection circuit and 2 layers plate through hole PCB.

Good thermal compensation control

Take a look at heatsink of driver board !!!

FR-4 COPPER PCB

I think it used FR4 COPPER PCB with TEFLON technology.

Big size zobel network wire

12AWG OFC copper wire for zobel network.

Good regulation

Good sub voltage regulation for drive unit (left bottom)

 

[ANALOG GUY]

Bottom layer

Bottom layer and single phase mosfet (very expensive parts)

 

[ANALOG GUY]

Rear view

Rearview (WBT !!!) and dual mono power supply

 

[ANALOG GUY]

Front view

Simple design but look so hi-end.

 

[ANALOG GUY]

Balanced position design

I like its chassis positioning design, but take a look at heatsink connection together it's very simple (now I searching for a new haetsink)

Dual 700VA toroidal transformer

Dual 700VA toroidal transformer with +/-70V power supply rails, I'll modify to 1000VA transformer and use Spargue powerlytic instead of RIFA.

Good binding post

I'll change to Eichman RCA and biding post, ummm WBT nextgen ?

My GAMUT D200 MKIII cloned version

Thanks Mr.Koran (my friend) for cloned them, I have some problem about single mosfet power output it's very expensive : 75USD each.

Now,I think it will work very well with Pass X2 : next step of cloned project. I don't like class-a schematic power amplifier because it's too much of heatsink and a lot of power consumtion, I think only GAMUT D200 MKIII Cloned best for me now.

Thanks

Hi Analog guy,

I dont understand your posts. You say you have found a source of diy boards and then you bought one cos its too complex to diy and then you thank your friend for building you one. Are the pics a clone or the real deal?

Pls check my first posted

If I have an opportunity I'll photograph them for compare with original Gamut D200

The PCB that I had told is "DIY MARKET" not this PCB (HOME MADE)
This PCB (3"*5") is input & driver module not included power mosfet, OK ?

I waiting for 6-7 months for buy them from secondhand hifi market (REAL GAMUT) ,Pls check a date of my first post.

Thanks
