Re: PSU alternative?
Has any progress been made with regards to offering an alternative QL PSU?
I seem to get asked every couple of weeks if I have any in stock - there must be plenty of QLs out there waiting for a PSU....

Re: PSU alternative?
Is someone registered in that forum?
I'd really be interested in five of these plugs.
Any help appreciated.
kind regards Paul

There are two possibilities,
1) ask for the data for 3D printer, and someone with 3D printer and enough time can print sufficient amount of connectors,
2) arrange a group buy (if Pavel will have sufficient time to print required amount).
Re: PSU alternative?
I have got response from the author:
"The model is not ready to be released, the printed piece was not tested on real QL already.
It will be released, but not now immediately. First it must be debugged (complex shape, small details).
Tell to all interested, that I'm working on it, just wait a moment.
They can also send e-mail to ..."

Re: PSU alternative?
On the contrary, the service manual says: "supplies 9 volts d.c. at 2 amps and 44 volts peak-to-peak a.c. to the board input on connector". Is this a mistake (or a big misunderstanding of mine)?1024MAK wrote:As I said above, you would need two transformers.

Re: PSU alternative?
44 volts peak to peak would be +22v and -22 v. Remember it's used to create a +12v and -12v rails. Also if I remember correctly to convert peak to peak to RMS (as the transformer would be specified in) you multiply by 0.707 which gives 15.554v. So I think the original quote should have been a transformer with a 15 - 0 - 15 secondary.Cristian wrote:On the contrary, the service manual says: "supplies 9 volts d.c. at 2 amps and 44 volts peak-to-peak a.c. to the board input on connector".
