The Acoustic Club

I'm not sure if I've joined this club yet, but here's my credentials at any rate. (There's a 361 power amp behind the 301 powering it - I should probably try to trade my 320 for a 370 at some point).

My goodness it occurs to me that I've lost track of who our last club number official was. Been a while since I've observed that function. Was it @Nick901 ?
Any way, anybody besides me noticing that 1 ACC rig is never enough and most here have multiple pieces of ACC gear?

I started a 'living archive' list a bunch of pages back and that could benefit from the addition of these fine examples.

Wonder how much operational ACC gear still lurks in the hands of bassists and guitarists that haven't found TB yet?

Indeed we should update. I can add a 408 to the list, and a 126

I just got myself Invalid Link Removed. $100 in GC.
I was between Fender 25 and Acoustic 25. Oh, well if something is wrong, I can return it or just throw the crap out in dumpster.
Anyhow. It works fine. For 25 W it pumps out nice amount of sound.
Room practice or super small coffee shop amp.

Good news - the MkII has worthy updates from the B100 in the video. The board is now better supported (who would think you'd need to worry about vibration - in a bass amp!) and they put an actual connector on the speaker out. Progress!

The bad news is it's not likely the kind of failure seen in the video. May have to work some for this fix.

Anyway I'll update what I find, both with the failure and with Acoustic's support. They've been cordial and professional (when you can get someone), and I do understand about "no user serviceable parts inside" from their (or their lawyer's) perspective.

Update - Acoustic Amplification did send the schematic to my tech buddy, and he did find the problem - broken trace at the input connector to PC Board. They use a single sided board, with all through-hole components. All front-panel bits mount only by the solder joints, so any shock/vibe action puts stress on the solder land-to-board "peel strength" (I'm a PCB guy by trade) - this one sheared off and broke the trace. So, for other new-gen folks, if your board looks like the one in the video I posted (#4955) and you get failure my bet is that's where you'll find it. And if anyone from Acoustic Amplification drops in here, if you go to plated-thru holes (even staying 1-sided) your solder joints will be "supported" and not subject to this particular issue.

Meanwhile he found the first stage op-amp (buffer, really) showing 50mV of offset (within spec, but...) so he changed that out "just because".

In other news my buddy reports the power amp device is capable of 70w, but the supply is (wisely) derated slightly (as it should be). I'll bet the 100w rear panel marking really is the line draw.

Back in my younger/bachelor days, I almost always had my amp in the living room.

Heh - I recently snuck my old Bassman Ten into the living room for practice access near my stereo, and am hoping that doesn't cause me to become a bachelor (yet again)...

Cheers,

Anyone know if a 301 cab will fit in the back seat of a 2003 Chevy Malibu?

Hard to say. Car are over all smaller these days. I used to put mine in the back seat of my 1965 Buick Special. 2 dr coupe. By myself. I can't believe that I got it past the fold down front seat into the rear seat. My cabinet still looks great.
Cars might not be as wide as they were.
Measure. The rear doors probably aren't big enough.
I say probably not.

Edited a cropped image from the catalog.

Also put my cab in the back seat of a 1940 Chevrolet. Suicide doors. It was an easy fit.

I usually had station wagons though. PU truck now.
My dad probably cringed when I took it upstairs in our 1880's house....surprised, come to think of it, that my parents let me bring it in the house.
