If you can mount one of those amps into a cabinet and use it as a powered box, fine.
Only thing that worries me somewhat is that it's specified *only* for 5 minutes continuous full power.
Fine for an audiophile listening to a Symphony at home; useless for a Rock Musician, even if playing in the basement.

Thank you for pointing that out, I didn't read if carefully before.
Here's the 7lb Peavey.. It's mostly box

But it's still large for a combo amp, and a kludge even if I wanted to go there.
What are the manufactures doing then in these inexpensive medium power combos? A fan and the whole chasis is the heat sink?

Well I went through all my Pearce docs and they have block diagrams but no schematics.  I could open them up and take pictures, scan the manual(?) if you feel it would be useful.

QuoteWhat about your soldering/mounting skills?
You can mount your power amp and PSU in the back of the speaker box, with only a power cable, switch and input jack(s) showing, together with a master volume if you wish so. ...

Yes, I have the skills, done a few Haffler kits along the way, good with tools and such but you see I'm not quite going into that mode. I'm searching for a small power amp package, and just been surprised to find how few have come up.. Likely I haven't looked in the right places.
Ironically, I was checking out one of my wife's bass amps- A GK MB200- It'd make for a tight fit (don't need tone controls), but 2lbs.. and I wonder if the price even can be beat.

Wow what are the odds. My first time here as well, poking around, looking for advice.

G2r, G2x, now recently a Mesa LoneStarSpecial Compact.
Cheers  :tu:

Hello everyone. My first post here, and I hope I've come to the right place.
I'm a long time musician, and have about 20 years in with a part time home studio.
My project here isn't exactly DIY.. More 'Assemble It Yourself perhaps.

I have a Pearce G2x preamp that was part of my rig along with the G2R head back when and I want to commission an open back combo' cab for it. I'm looking light preconfigured plug-in 120vac' SS power amp module to mount in the back.

I'm not looking to build a real high power rig, 1-10 or 12 inch, but given the light high efficiency amps available presumably I'd want to land on 'more than enough than come up short.
I also don't know whether I need to be concerned about the power amp's tone? The Pearce (in the G2R config at least) does real well in that regard, but this is new territory for me here.
So, Hello again. And thank you for any help and guidance.
