PRINTING
Wix (bless 'em 😖) have changed their image format - again - to avif just to make them awkward to print. Unless you want to buy a converter, the easiest way to make a hard copy is:
-
Left click when the magnifying glass icon appears and wait for the picture to clear.
(On a touch screen, tap on the image). This will display a higher res file. -
Right click and 'save image as' to somewhere as an avif file.
(On a touch screen, touch and hold down to view the menu) -
Upload the saved file to your Google Drive.
-
Open the file and use the print menu to make a hard copy or save as a pdf.
The flanger is designed around a Reticon SAD512D (8 pin) bucket brigade delay chip, £50 to £60 if you can find one. If the Flanger doesn't work (very quiet or no signal with the effect switched on) then Murphy's Law says it's going to be the 512. The only good news is that it's in a socket. It's possible to buy a 16 pin SAD512 (without the D) a lot cheaper, but they're not a drop-in replacement.

Watch out for IC6. It faces the opposite direction to all the others.
