Well, I do suspect it would be easier to do the mod than to populate the boards myself whole without error.
Also, I intend to test it out pre-mod so that if something fails I know it's the modding attempt (this will simplify debugging if needed)
As for the transformer, yes, I did notice that one of the voltages is "over spec", but also, it's being sold for pennies so I decided to ask if it will work okay or would cause issues
If you are going for the 48v method by Catear, why not do the assemble yourself? Buying from Vulkan35, Tindie or anyone else is not the best option since they have to test it and unless both parties agree to send you a pcb untested and unfinished (No MOSFETs , regulator etc ).
You will have to change the MOSFETs and do other mods to support the 48V as described in previous chats by Catear himself however he shared not many instructions on how to do this.
Please note that your secondary voltages are wrong since it has to be 24v and not 28v.
I have something to do these days, I will sort it out and send it to you when I have time.
Thank you very much!
edit---
P.S.: if possible, please also photo how it's wired up to the transformer, just to make sure I don't screw up something when connecting it
P.P.S.: Would a custom transformer with three secondaries (12v/1A, 28v/6A and 48v/6A) do the trick? The company I plan to order from has such a unit as "leftover" and I might grab it with discount
Hi! I am not affiliated with any tindie seller (that place was just the only one I googled up where populated Unisolder PCBs were on sale)
I am now wary of tindie (thanks for the warning!) and would very much appreciate pointers as to where to buy a fully populated Unisolder kit (I'm not cool enough to properly populate one myself, I'm pretty sure I'll end up buggering something up, potentially destructively)
Maybe Catear would be so kind as to sell a set with the 48v/C470 mod already "baked in" ?
Hello Alexandra, you have a nice plan and gift ahead. 1) I am still waiting a reply from LoveDIY for my faulty PCB. 2) I am still waiting for the parts I have ordered to maybe fix my new Tindie PCB at my expense.
I read a post similar to yours from JANE and that what triggered me to buy a ready one. Today I can confirm it was a mistake, unless you here to promote lovediy pcb I would suggest to ask if you can buy something better even if u pay little more from other members.
I plan on getting a Unisolder readymade (from tindle) and a good custom transformer (I know a good factory that makes toroidal transformers in my country).
It is going to be a gift.
Modding it so it can properly "do" 48v + C470 cartridges would make it even more awesome gift, methinks, and from reading the thread (okay, most of it ) I've gathered you've succeeded at doing exactly that.
Unfortunately from reading your posts I didn't quite comprehend the full scope of such mod (which components need to be replaced? etc.)
When you have time, would you be so kind as to document / explain / photo your mod, so I can reproduce it, hopefully without breaking anything?
In fact, the 48V C470 current is not much larger than 245, but smaller, 250/48=5.2A, the circuit board can withstand this current, and there is a 36V voltage regulator in the front of the voltage regulator chip, which can ensure the main The power supply of the control board circuit is normal, but you need to pay attention to the withstand voltage value of the resistance in front of the Zener tube, and the withstand voltage value of some devices that have passed the voltage of 48V. It needs to have a withstand voltage of 80V or above to ensure that the circuit can be under 48V. Work normally without being burnt
