Anything new now? And the amp replacement? Anything new?

I would be very interested in a replacement amp. I too have developed the hum of death in the original amp.

 You could definitely put me down for one.

Ever thought of modding one of those dayton 1000s to run two otherwise stock MFWs since you have most of that stuff in house?  There are a lot of us out there with two or more MFWs looking for amp options.

Or a combination of SA1000 dayton amp with (2)upgraded drivers?

At least you could move some amps since your still waiting on drivers.....

Hey everyone...  Have 2 MWF15's.  One amp replaced in January '10 (still functioning) and one with an August '09 original amp that just started humming tonight.

I really only NEED one amp but, depending on price, would consider two to have a standby...

Any new news?

My MFW-15 amp (updated version) just started humming.  Count me in for one if/when available!

Definitely in for 1.  I have a v3 that was sent to me as a replacement this year before all the legal stuff started.  Now that just hums very loudly and wont work. 

I will check this thread daily and order ASAP as its available.

Is this the V3 that does not use the top control panel?
I havent heard of that many of these failing yet.

Sorry Kevin, My bad that was a typo, I have an V2 amp that was sent as a replacement early this year.  That has crapped out also just like the first one.

If you want visual or schematic differences, the best person to ask might be Murrell since he's repaired some of the v1 and v2 amps and IIRC, may even be reselling the v3 leftovers. He's posted here and on other audio forums, so shouldn't be too hard to track down and he's a nice guy if you have any questions.

Operationally, one difference between the v1 and v2 amps was the soft pop made by the v2 amps when going automatically from On to Standby (perhaps at other state changes as well, but you get the idea). The change was inaudible on the v1's.

I haven't seen one, but understand the v3 amps are a complete redesign and obsoleted the separate control panel for Gain, Phase, and Crossover by relocation to the back plate on the amp itself.

Others have mentioned differences in performance, but I don't recall seeing any details to confirm what's actually different.

Thanks T.T
I purchased a b stock late 2008 and a "new??" inmid 2009.
I've had no problems with the b stock till recently and the new one had the hum right out of the box. Was curious whether the b stock may have the newer amp v2 though I bought it first.
I cured the hum in the new one by pulling the amp and re routing some wires as was suggested in the av123 forum. The b stock now has some hum but both seem to work (though not dialed in) Thinking of just replacing both with either a v3 (though I don't understand the lack of controls or is it just moving them??) or waiting for the new offering coming up here.

doug067,

they just integrated the controls into the amp. in fact the V3 amp is completely redesigned.

With a V3 amp, you might see the upper controls (aka knobs) still in place but there maybe a label that sayes "These control inoperable"

For the humming v2 amp guys, I did the capacitor fix over the weekend and my baby is back to normal. I used the capacitors listed with the exception of the one I could not find at Radioshak. I got a TV repair shop to solder them in for me, and he replaced the 22uf 150 volt one with and even higher volt rating, so hopefully it does not hurt anything. FWIW, only one of the caps looked bad, and it was one of the two identical ones.
Thanks Murrel

My v1 amp blew out tonight.  I had minor issues earlier and had contacted AV123 for a replacement that was still in the box.  Tonight I worked on swapping out the v2 version.  It didn't exactly fit well.  I find myself trying to hunt down my mallet.  Anyone else have this experience?

I'm posting because I would definitely be interested in a replacement amp.  Sign me up.

Thanks,

Nowell

I put a V2 amp into a V3 opening. It was a tight fit. It didn't snug down into the opening until I tightened up all of the screws. Just FYI, I didn't went around to each screw and tightened it a little, move to the next screw and tightened it a little and so on. I did about 3 rounds to fully tighten all of the screws. Be gentle or you can strip out the MDF.

Anyone attempting a DIY cap replacement per Murrell's documentation should note his recommended replacements already include a 1-step increase in voltage rating compared to the OEM caps.

Parts Express carries all 3 values if you want to replace the entire set of 4 caps noted.

Are there any issues with the v3 amp?  I've been without my beloved mfw-15 since July/Aug.  I'd really like to get the new one supposedly coming out soon, but I'm getting a little impatient and not getting any warm fuzzies that it will, in fact, come out "soon".  Are there any other options out there that could work well?

Thanks,

I am in the same boat as Carp. My amp has been out since July and don't want to want any longer.

Any updates on when this amp will be available?

Or are there any alternatives?

Folks......

Developing a new amp to work in this application takes time, there is a reason most manufactures dont anounce new product till its in production.  I havent had time to talk to mark about it as we both have been very busy.  I will talk to him later this week and post up.

If you can operate a soldering iron, I would recommend Murrels short term cap fix, its cheap and easy to do, its not a long time solution, but it does work for now.  This will get your subs back up and running till we can get a new amp fully sorted and working properly.

Just found this thread and all of my ??'s could've been answered by reading here instead of pestering you via PMs.

I am interested in two MFW amps.  Thanks!
