1.7mm - it's the same for the various output current options.

Hi All,

The psu modules are obsolete and hard to find. That's why I decided to make one myself as alternative.
It contains a LM2676 regulator and two AP3418 regulators and all three voltages.

Works OK, only a small mechanical error I still have to fix.(that's why the red wires are fitted between JP1 and 2)
When finished I will try to post the artwork somewhere .

Hi

The required power modules for the Winterhill project are stocked by Farnell UK part no 1736768.
They have 175 in stock as of 19:30 on the 28/07/22 at £5.90 each.
I have not long received mine, so my Winterhill is now complete and working well.

Many thanks to the BATC team for a great DATV receiver.

Tried to order through farnell uk but they won,t send it to the netherlands. Farnell .nl doesnt sell to private customers. Now when you try to order in the Netherlands you are forwarde to a site from Sinuss.nl. Who has any experience with these people??
