Newbie question , can I modify the armageddon power supply to spin my LP12 at forty five r p m or just stick with thirty three and just be happy I found on stateside?
Welcome Chris.
The Armageddon only does 33 1/3rpm. If you want 45rpm then you will need to use the Linn 45rpm adapter on the drive pulley. It’s a fiddle though and worth using a different belt too so your 33 1/3 one doesn’t get stretched out of shape.
