Sold Commodore 64 PSU replacement/upgrade board (rebuild kit)

I have an auto-voltage thing that does everything on it's own.
Should be ok as commodore is working.
What would fail if the 9v ac weren't going through?

I think that the datasette and the SID chip uses the 9VAC from the PSU. If your C64 is working as expected, maybe it's just your measurement tool that doesn't show the (AC) voltage correctly.
 
New batch available

Two boards reserved for pauljh (PM:ed interest)

EDIT: payment for two boards received from pauljh

EDIT2: another two boards sold outside Amibay

I will try it shortly!
 
Received last week (Incoming post seems to be delayed on Spain)
Assembled and tested OK. Measuring 5V on datassette port is 4.9V, is a bit low but all is working OK.

Positive feedback left (y)

Thanks for the feedback! Yes, the 5V can be a bit lower due to voltage drop in cables and traces. It should be no issue though.

Hi there,

will the pcb fit into a 251053-11 PSU, too?

Here's a picture from inside:

Probably not as the positions of the cables (and the dimensions of the board) are different.
