I am happy to have a look at it if you want to send it. Although the PSUs seem to be more reliable than the power amps. Quote Link to comment Share on other sites More sharing options...

There is a 15” one for sale as spares or repairs on eBay, which powers up, but has another intermittent fault. Wondering if it’s the same PSU?

Wondering if it’s the same PSU? Almost certainly, although they claim 1400 watts for the 15 as opposed to 1200 for the 12. Probably just marketing BS anyway.

Chienmortbb Posted November 25, 2023 Share Posted November 25, 2023 This is from the User Manual, so the they have the same power supply specs. Quote Link to comment Share on other sites More sharing options...
Hacksawbob Posted November 25, 2023 Share Posted November 25, 2023 (edited) There is a solderable jumper on your ladt picture that you connect for the 15, and presumably desolder for yours. It says '115 jump' on the pcb Edited November 25, 2023 by Hacksawbob 1 Quote Link to comment Share on other sites More sharing options...

agedhorse Posted December 11, 2023 Share Posted December 11, 2023 Good grief, if you don’t know what you’re doing, leave it alone!!! The 115 refers to the line voltage configuration of the SMPS, not the speaker model. To the comment about SMPS being too noisy for audio applications, look around at the highest quality audio applications and you will see SMPS. Limited experience results in limited knowledge. 1 Quote Link to comment Share on other sites More sharing options...
Hacksawbob Posted December 12, 2023 Share Posted December 12, 2023 Still learning and trying to help. Thanks for your input. Do you think 115 refers to the 110v mains input? Back in the thread it was suggested to get a board from a 115 model and swap it in as there was one on ebay. Quote Link to comment Share on other sites More sharing options...

No, it’s part of the 115V/230V configuration circuitry. Hook the 115V version up to 230V and the power supply will fail spectacularly. There may be other differences in addition to the jumper(s), so be aware of this before making any assumptions. 1 Quote Link to comment Share on other sites More sharing options...
