Remove rust / paint top grill 1200B

[ocdecio]

Just finished recapping an otherwise pristine 1200B. It sounds incredible, but its physical appearance is not making it justice.

Any recommendations on removing rust or maybe also painting the black grille? My biggest concern is preserving the original stickers.

Also - what could fit as slider knob replacements? It came missing 3 of them.

Put it in a WC1 wood case and you won’t have to worry about the condition of the metal

Hi @Steven Tate I have mixed feelings about WC's. I am always concerned it will make the thing run hotter than necessary. But damn it looks good!

I’ve never had trouble, but I rarely run it for more than one side of an LP - 20 minutes or so.

I can't stop listening to mine. It is too good! And I have to say it runs leaps around the other 1200 I restored. It has basically ALL original transistors and diodes. I just recapped and left the other stuff alone just to have a taste of how it sounds. I have to say it sounds better than the 240 too.

There are rust killing products. Just mask off the sticker first. Once the rust is killed and the cover is cleaned, just repaint it with the sticker masked off. Or use a.wire brush or steel wool to k ock down the rust and repaint. I've never had a problem using the wood cabinets. They are vented at the bottom and top with space on the sides of the amps that have side vents.

I think I can use painter's tape to mask off the stickers - I don't want them to peel off. I'll try my hand at the wire brush and paint - thanks!

If the cover is really pitted, you can use a hammered finish spray paint. It's kind of bumpy and hides imperfections well.

That's a great idea! And it is how the first Marantz made used to be painted.

I had a cosmetic problem like that (or at least my 250M had) - I had an industrial painter of very high quality - a really good one to mask the labels nicely and spraysanded (sp?) the metal. After that he used a special technique he called flake-spray-painting - he sprayed the vent with that and the result was absolutely stunning. First he measured by computer and optical gear how dense the flaking should be- how high -and how big ... to make the flake paint look exactly like original. I can't see the difference...

The painter usually was doing paint jobs on new Bang & Olufsen gear -

flake-spray-paint should be the keyword - but don't do it with metal flakes to make it look like candycolors - use opaque black paint with small flakes in it - the shine should also be considered. . ask a pro..they probably know the right technique.....

Wow that sounds great - I wonder if I can find a similar process around here.
