The good thing about this speaker is that it comes with passive crossover for the midrange and tweeter. This make it relatively easy to replace the electronics with generic class-D amp modules. If it came with full DSP/electronic crossover (as in later versions) then it would be a lot harder.

Thanks, I’ve had an early Zeppelin in pieces awaiting some action for a few years now - similar symptoms with blown supply plus the FETS on ch1 of the amp board blown to bits - both the 25V and 5V fuses on the PSU board toast which was going to be my first port of call before even thinking of tackling the amp etc - but after what you’ve found I’m inclined to try the amp transplant - useful to know it has 3 channels as the amp seems to have 4 channels with the sub being bridged somehow from the left and right as it passes back up to the outputs 🤔 Could be interesting 🤨

Thanks for the video, Andy.I had a similar experience with a friend's Sony Bluetooth subwoofer. The little 3.3V DC-DC buck regulator had gone faulty. I replaced the chip ok and the 3.3V was fine, but sadly when it went it took the Bluetooth module and sound processor with it. I'm currently converting it to an analogue subwoofer with a sino-tat* class-D amp and a homebrew low-pass filter. *My name for "cheap Chinesium"

Hi Andy, been here done that many times, hence why they changed the design quite early in production. good video again Buddy

Good effort, a real shame it didn't work out. And it would be a very interesting project to try and get it going with that Chinese control board, especially if you could add in a Bluetooth module. Thanks for sharing! 👍

the later ones aren't much better. An overload in the amp can make the SMPSU board explode.

Hi Andy, did you make any progress in that retrofit-project with that different amplifier? Best greetings 🙂
