First off. Everything I've done can be UN-done, easily with some epoxy or plastic repair kit at body shops, etc. Repaint & voila!! The tuner leds, VU's etc. ALL can be removed again by even the most amateur hobbyist if they are familiar with boomboxes & tools. The chassis, cabinet & ALL other parts of the boomer are still very serviceable & the unit can be serviced as normal with a few extra connections to deal with. That's it.
If it was in minty shape when I got it, I wouldn't have gone so far. Since it was covered in grime but fully working, it was a prime candidate for a 'custom' restoration, as I call it, since it isn't a full restoration in the traditional sense. If it was a rare unicorn like the early Conions or an early MARANTZ, SILVER, National, etc, then I would not do it but M90's are like Firebirds or Corvettes. There are a million of them compared to other models, even tho they are kick ass cars. The m90 & m70 are like that to me & I did not hesitate to mod it fully. Its pre-sold to a friend anyway. 2 other guys on eBay are hot for 1 too & I had to turn them down for the time being. No joke.
Besides, whether you agree or not with what I've done, you can't deny it takes imagination, determination & a bit of artistic flair to pull this off the way I did & I could care less if traditional collectors would appreciate it. I can park that box anywhere & have an instant DISCO dance party.
