#62 Jamo Sub 200 modding

For background / context: https://mehlau.net/audio/multisub_geddes/

I had been off-and-on "hunting" for a twin, for my Jamo Sub 200 that i bought and revived years ago. Partially for SPL reasons, partially for the multi-sub approach mentioned above, and most recently, for actually sitting my couch on top of the subs.

At long last, a couple months back i finally found one locally, and in matching black finish. And with the 5.1 Jamo speakers it came in a set with, to boot! Those might get reused / repurposed later, (i'm thinking, in a manner similar to one of my previous projects).

#2 Amphion Impact 500 (DB Series DB5004) subwoofer amplifier autopsy (and repair, hopefully)


Right, so i've had this amplifier brought in last week (sans the subwoofer enclosure itself). When i noticed the brand, i remarked to the owner that, to the best of my knowledge, Amphion stuff is anything BUT cheap. He confirmed, this whole thing having costed him something over a grand(!!!), a couple years ago.


It had allegedly been serviced before, and he pointed at an electrolytic cap. A ChemiCon SXE - totally out of place on a board otherwise full of CapXons. Yep... Oh joy...
