I agree, just make one out of a thin piece of tin with a 90 deg angle. The one nice thing by us is the local dump. They park a pickup next to the dumpsters and people toss there junk into it.
Using the top of an old vcr comes to mind. Slice the top rear section of the cover and belt sand your cut marks. Line it up and drill out the screw holes..
I have the one off of my 2275 right now, waiting for me to put vellum paper in. I can trace the shape and send it to you. There is always a certain pride in making things yourself and its great to see you are not one to half ass something.
Owning a Nice receiver like yours is a true joy and it deserves respect.
With your permission i would like to post this statement i came across today about a 2325, that i think of as the 2275's bigger brother. They mirror each other in detail to excellent construction.
This is from a review/comment section.
"How do you start to review a classic piece of iconic audio from the mid '70s? Sometimes I sit in my darkened living room with the Marantz 2325 showing its muscle AND characteristic blue glow, listening to Sara MacLaughlin's "Angel", Ravel's "Bolero", or Mike Oldfield's "Tubular Bells". This beast delivers pure listening enjjoyment with a damping factor that gives one of the tightest basses you'll ever hear from a receiver. (It might as well be blue-faced Marantz amp. for you can't tell the difference with your ears).
You know it's powerful when you turn it on and for just a few milliseconds the lamps in the room on the same circuit dim while the massive power transformer powers up.
It's been 31 years and I wouldn't trade the 2325 for anything today! As a matter of fact it's stipulated that when I die, the 2325 must stay in the family, to be handed down like a diamond ring (I'm not sure the younger generations would understand why but when those of you who, like me, grew up with low-fi noise producing trash and were then introduced to hi-fi audiophile components like Marantz, you DO understand) Now excuse me, while I wipe away a tear and subdue the lights and listen to the sweet, pure, distinct, hair-raising sounds and looks of my friend, the Marantz 2325!"
That was well said.
