Single channel sub woofer amp w/slightly older NX 150 and older PS-3 = Post your Solid State pics here.

Sounds pretty good, too. ... Several hours under load = room temp heat sink and no sign of hot spots ...

Default Nxv200 listening impressions

Guys,

I have been using the NXv200 modules in a stereo amplifier everyday for the past 3 years and they continue to deliver.

Pros :

- Extremely neutral without being dry or analytical
- Tremendous bass authority. The sheer grip they have on dual bass Peerless
XXLS 12 inchers in a 3 way system is unrivalled.
-Revealing of the slightest change in an audio system. ( CD player etc)
- Superb soundstage

Cons:

-Lacks the warmth/lushness of a good valve amp

It is excellent partner to a warm sounding speaker.
Just be careful not to use them with overly siblant tweeters.

BEst Regards,
Chloro

I can only say good things about the NXV200 from Ausssie Amplifiers. The other day I had it playing for about 10 hrs straight at very high volume (party) and showed that the NXV200 can deliver a big beautiful punch with not sign of weakness at all. even though I pushed it really hard for many hrs the heatsink got just a little hot. I have had many amps and so far my favorites are LM3875 from Audiosector and the beast NXV200 from Aussie Amplifiers that is in my living room playing beautiful. Well done Anthony!

Default The amazing NXV200 story

I currently use 8 of these modules in a 2-way active system. Using a ballanced preamp and a ballanced active filter as well as 2 NXV200 for each speaker with a 1200Va power supply and 60mF buffercap per balanced set.

Compared with a top of the line power amp in passive mode its like removing a thick velvet curtain from your speakers. These modules are simply amaizing.

Next step is to use them in a 4 speaker active system where the modules are mounted on the magnet structure of each speaker, making the speaker wires as short as possible. The trails were promising.

What OPS devices do your amps use? L-MOSFETs seem to have evaporated from the market, I was curious what you're using. Are these the IRF switching transistors?

Hi tcpip

Currently I am using Toshiba Vertical MOSFETs 2sk1530 and 2sj201
However as these devices are now no longer in production I will be moving
back into Dual Die Lateral MOSFETs from Exicon.
The Toshiba devices are still in good supply as surplus supplies are everywhere
So it will be a slow transition into these Exicon devices which are in plentiful supply.
This is the first of the Exicon based amplifiers I am producing.

Even these Exicon devices seem to be available only with Profusion Plc. Findchips.com does not seem to be able to find any other reseller anywhere. Maybe I'm not looking widely enough? Can you point me to any online retailers?

And, if it's okay to ask, how much do the circuit design and component values change when you swap these devices? Can I move easily from the 2SK1530/2SJ201 to ECX10N20 and ECX10P20, for instance?

Profusion are the manufactures of the Exicon devices.
I buy directly from Profusion and can supply them.
They are not a direct replacement to the Toshiba devices and do require
modification to the Cdom compensation and output stage pinouts.
