2x150W Amp module for sale

If the bottom is thick enough, you can also drill a 2.5mm hole and use a 3mm x 0.5mm tap to make the threads in the case. That's what I did.

Example for illustration only, I don't know the quality.

Thank you very much

Eric,
Any progress on FFA003?

Hi, Bill

During mid of this month, the I/O buffer with DIP opamp/Volume control will be ready, then we can open the first -batch order for friends. Sounds a little delay than the schedule. while more resources are put into working on the universal FFA002V2

Thanks,Eric

i should have waited for this new IO board before asking you to send me the additional old IO board today....😩

 

[Erica.C]

Hi, Nick
Currently, we only design this for the FFA003 IO board, we have not re-designed the FFA001V3 IO buffer. So, no worry about your choice today.
If I do re-design the new IO buffer for FFA001V3, I'll announce it here 😉

Thanks,Eric

 

[zoom777]

Ahhh I see I see, 😂 thanks Eric

Eric,
Thanks, I have plenty projects to keep me busy for now but just letting you know I still have interest in the FFA003.

Hi. I bought and received an amp with unbalanced buffer board and am just now getting round to building a case. My question is how do I connect a volume pot to it, and what impedance pot should I use?

Well noted, thanks Bill.
I will PM you immediately once we're ready.

Thanks,Eric

For the current I/O buffer circuit design, I don't think there is a proper way to wire in the pot. It's better to have a pre-amplifier for your system.

Thanks,Eric

Anyone else using the FFA001V3 Hi/Lo version? How are you running two boards? In one case, or active speaker build? Do two boards play nice if sharing one power cord?

 

[CANNON-FODDER]

@Randy Bassinga you might go back and review the six channel by @von Ah (here and in other threads). IANA[EE] but if three boards coexist, changing the power limiter on one channel doesn't seem like it would make them fight. If you need more power than (whatever the base power line is there, it's ~15A here) you are now into breaker limits and separate lines run from the main power box anyway.

3 FFA001 modules (I ordered them way back near the beginning of this thread) drawing from one IEC mains connector works fine.

Hi, All

Announce this FFA003V1, universal power supply(85-264Vac), mono output amplifier;
8ohm -- 150W;
4ohm -- 300W;
With XLR balanced input, and volume control. 🙂

 

[bonjonno]

Hi Eric. How much? Does it come with the mounting plate? Dimensions? Can it handle a 2 ohm load? Thanks.

 

[Erica.C]

Hi, Jon
Thanks for your reaching out.
It can support the 2OHM load.
This new amplifier board is $64.9 Inc. I/O buffer and Al plate. Still, the mating cables are free of charge 🙂

Thanks,Eric

I’m very interested as well. I’d lost track of this thread but now my interest is rekindled. I really need to read through this again
Best

 

[Erica.C]

Yes, Please.
You'll find a lot of interesting things, and that may stimulate you to build your own lovely amp~

 

[CANNON-FODDER]

In for two (as before), will send PM.
