I have a philips 22ga 418 vinyl player and it’s not a standard shell. I’ll attach a photo. Please tell me which cartridge is suitable for this shell.
The Philips 22GA 418 uses a proprietary cartridge mount, not the standard half-inch type. You’ll likely need a Philips GP400 or GP401 series cartridge, which were originally made for these tonearms. If you’re unable to find one, consider looking for compatible NOS (new old stock) or refurbished units online or in vintage audio forums.
