Flexinoodle Posted November 29, 2019 Report Share Posted November 29, 2019 Anybody know of a good supplier ? Everything I am looking at is switchmode or EU plug. Quote Link to comment Share on other sites More sharing options...

Hawkeye Posted December 3, 2019 Report Share Posted December 3, 2019 Here is a discussion with a similar question: so, from that thread, this here: http://www.buythis.co.uk/product/4927/genie-psu500-in-line-12v-dc-500ma-regulated-linear-power-supply might still work? You are probably fine with a high quality modern switching PSU as well, as long as the switching frequency is well above the audible range, especially as the SIDs are a bit noisy by themselves :).

Flexinoodle Posted December 4, 2019 Author Report Share Posted December 4, 2019 Tried a regulated switching supply, looks like it burnt out my backlight as per a ton of threads on here, but I dont think Wilba is around anymore to contact is he.

Flexinoodle Posted December 4, 2019 Author Report Share Posted December 4, 2019 (edited) Hahahah shipping on that is nearly twice the cost of the PSU :) I think i probably need to get a new screen too, OLEDs working on sammich yet ?

Noise-Generator Posted December 7, 2019 Report Share Posted December 7, 2019 I use a 12/5v Iomega PSU and it works pretty well. Quote Link to comment Share on other sites More sharing options...
Flexinoodle Posted December 7, 2019 Author Report Share Posted December 7, 2019 How can i test if that power supply is linear and regulated ? They sent one, but it isnt the one in the image and it is pretty small too. Quote Link to comment Share on other sites More sharing options...
latigid on Posted December 7, 2019 Report Share Posted December 7, 2019 If the PSU is heavy, then it has a wound transformer in it, so it is a linear PSU. If it is light, then it is switching as the components are much smaller (also sometimes containing a small transformer). Very few of linear ones are also regulated, but they do exist. You should measure something near the rated voltage with a multimeter. Better to load it with a 1k THT resistor. If the voltage is wildly different then it is not regulated. The current capacity of a switching PSU is much higher than for a linear PSU of the same size. Anything over a few hundred mA will be a switching PSU.

Flexinoodle Posted December 14, 2019 Author Report Share Posted December 14, 2019 Pricks sent a completely different switched supply, seems it is near impossible to get a supply for the Sammich now in the UK. Quote Link to comment Share on other sites More sharing options...
latigid on Posted December 14, 2019 Report Share Posted December 14, 2019 It is the same in much of Europe, I think because transformers draw some current even when the secondary is unloaded. The only way to kill the power is to switch off the mains (which I always do) or to unplug the wallwart. So it is seen as a power-saving scheme. Try rummaging through a second hand store or fleamarket for an old one. Alternatively you can still buy transformers and build your own, but need to be experienced with mains voltage and case it safely. https://www.reichelt.de/Transformers-toroid/2/index.html?ACTION=2&LA=2&GROUPID=8880 Quote Link to comment Share on other sites More sharing options...
Flexinoodle Posted December 14, 2019 Author Report Share Posted December 14, 2019 (edited) Yeah im not even chancing building my own, that is a recipe for death, it is time the Sammich went in the bin, it is of zero use to me now to be honest.

latigid on Posted December 14, 2019 Report Share Posted December 14, 2019 Before binning, just try the one you were sent. The sFM has linear regulators for both power rails, so the noise might not be at all bad! Quote Link to comment Share on other sites More sharing options...
Flexinoodle Posted December 14, 2019 Author Report Share Posted December 14, 2019 its a SID not an FM, but im burnt out on this, spending hours looking for a power supply after the last one killing my LCD seemingly, its just an outdated design that is no longer usable to be fair, everything is switchmode now.

Flexinoodle Posted December 14, 2019 Author Report Share Posted December 14, 2019 OK gave in and tried, the backlight is definiately dead, not sure if i should chance trying a new screen or if it is just gonna burn out that too LOL. Quote Link to comment Share on other sites More sharing options...

Hey flexi! Great to see you back. A discord server for MIDIbox is a great idea! Has so much more features than IRC, now why didn't I think of that!

Smithy Posted December 14, 2019 Report Share Posted December 14, 2019 Just now, Flexinoodle said: https://discord.gg/V3uK88p There is the MIDIbox Discord Great work. Now we just need to add channels and moderators. With Peter and Andys blessing we could push it on the midiphy facebook page also when its ready. We have quite a following on their already! ;) Quote Link to comment Share on other sites More sharing options...
