Rockola stepper question

Hi all

Quick question, will a 1738 stepper work with a Rockola 1454 and wallbox 1546 or 1454 without the need to modify anything?

Thanks in advance for your assistance

From what I know stepper 1738 was backwards compatible, a 1725 not upwards without modification.
But make sure you have the extra scan wire for the scan impulse which connects stepper and power supply.
Wallbox 1546 was made for 1454 anyway.

Thank you Hildegard.
