Best cab to put into an old Markbass combo?

[Flipflop Mojo]

I can't seem to let go of my older Markbass CMD 115 (see my profile picture). The amp has survived 2 repairs in 4 years and still sounds farty so I need to move on. The speaker is just perfect in my home studio and it sounds good with a newer Gnome pro 600 that I recently bought off Talkbass. However now I want something class D or hybrid that would slide into the back of the MB combo cab with the fan in back. I am skeptical of Mark Bass amps because of the pain of those repairs, so an alternate brand would be best. Thanks for your wisdom! These are the amp specs:

1X15"
PIEZO TWEETER 3.5 KHZ

400W RMS
40HZ TO 18KHZ 100

8Ω

REAR

Spec's you need to give are; [with rear fan] for Amp I assume not Cab as your header states

HEIGHT: 2 rack units (3.27 in. / 83 mm)
WIDTH: 10.87 in. / 27.6 cm (19 in. / 48.3 cm with optional rack ears)
DEPTH: 9.84 in. / 25 cm

All Little Mark Amps will fit after removing top; since you don't want MarkBass Amps size is important with others and most likely you may have to be creative with modifications for stability.

I wouldn't waste the time money or effort.
The Gnome is class D.
Just Velcro it to the top of the cabinet and turn the empty pocket into a cable storage compartment..

If you decide you do want another MB amp, I just pulled a 2018 Combo Head II (Little Mark III 500w) from a CMD121 (literally today) and it's about to go up for sale. PM if interested. Looks and works excellent. (Top plate transplanted from the new head)

Good to know, thanks.
