The Acoustic Club

Recently acquired this 370/371 stack for $280!! Sounds and runs amazing, just need to build my own grille for the bottom. Also recently got the 230 for $100! Definitely needs some servicing done to it. Acoustic collection is growing!

As a chronic refurbisher of all manner of things, I envy your potential with these finds.

Soon, I will reveal modest mods made to my B100c - retro grille cloth, retro knobs and custom Tolex riser - when completed...

You got some deals there! I'm absolutely loving my 370. Just flat out one of the best bass amps made. I recently got a chance to do a side beside comparison with a Markbass head. I've heard so much about these amps.
The 370 totally blew the Maskbass away. I basically had to max the Markbass out to even get close to the Acoustic, with the 370s controls and graphic set flat!
Good luck with the refurbishments!
 
Just swapped out the OEM no-label speaker in my B100c for a new 12" Eminence Deltalite II - just what the doctor ordered!

As recommended by a forum guru here, it is a louder amp now going from a low end 4-ohm to a high end 8-ohm driver. Wasn't expecting that but the smoothness and depth of sound IS what I expected and that was deliverd. Pedal changes are much more evident too. All upgrades are complete...

Am building a duplicate style kickback cab to put the 12" OEM speaker into as a spare/monitor/whatever...

Haven't used my 370/301 rig in a while, using a 360+300 slave with some smaller cabs on recent shows. But I decided to use the 370 set-up instead of my Sunn or Hiwatt at rehearsal yesterday, and damn I forgot how great that rig sound. Hitting the front end with a Suncoast HD-1 and Chasetone Secret Pre slams the front end of the 370, and gets some of the best grunty overdrive you can get. Need to try out the 360/300 into the 301 to A/B the 360 and 370 front ends, but the cab certainly has a big influence on that grunt. I also usually use a 301 IR when recording into my DAW, in tandem with a Sunn 2x15 IR, which is a great combo.
 
According to the 370 manual, it does 205 - 230 watts rms at 4 ohms (5 and 10% distortion) and 325 - 365 watts at 2 ohms. The 220 is 125 watts rms at 4 ohms and 160 watts at 2 ohms at 5% distortion.

I'm wondering of there's a significant tone difference between the two at lower volumes.

I don't put much faith in those marketing numbers. The power sections in both amps are very similar with a slight nod to the 220 for its updated power transistors. They share the same power transformer, power supply specs, etc. The 320 added another pair of power transistors for greater power, but the architecture of the 220 more closely mirrors the 370.

Has anyone modded their 361 cabinet to accept standard output from a normal head (bypassing the power amp) as well as the normal 360/361 arrangement? One of the main reasons I picked up the 370 rig was to use the cab with any of my heads, but if I could reduce down to one 361 cabinet it would be a lot more versatile. I could always bypass the internal amp completely and just use the 300 to power the cab when using the 360 pre, but thought I'd ask. I'm thinking a toggle switch on the back of the cab connecting the input jack that routes either straight to the speaker, or to the power amp and then the speaker.
