Summary

This is a model of the lamp housing that usually melts in many 70's era Marantz receivers.

Instructions

I haven't yet printed this, very soon....

It should be a direct replacement part for part #0917 in the 2250 service manual (available for download from audiokarma.org). If yours is melted like mine, you'll know exactly what part you're replacing.

Expect some updates as I print/adjust it to fit.

It could probably be cut on a CNC mill as well, but that's not a tool I have experience with.
