    I have a fender bronco. The little tweed amp.I live down hear in Florida, right on the ocean. The air. is very corrosive to metal.. Well on our back enclosed porch,I left it out there for only a few days. All the metal is rusted. Surface rust. To clean it up, I will destroy all the lettering on the chassis.Can I get a replacement chassis?I was also thinking about ,Converting it to a small tube amp. I see those kits advertised. 5f1 ,I think they are. Is there a way to clean up this chassis, Can I get a silk screen done to the cleaned up chassis? Or try to convert to a small tube amp? thanks.

    I don't think it would be worth it to try and do a restoration on something like that. The cost of cleaning up the silkscreen alone would easily exceed the replacement cost of the amp. But....that's just my opinion.

    I haven't seen the chassis out of one of these so I can't say for sure if it would be a good candidate for a tube amp conversion. I have seem people make adapter plates for the top cutout and a new rear panel in order to convert it to a hold a 5F1 style chassis.

    Try guitar polish. I used the Gibson in the orange bottle on my '58 Twin and it cleaned it up nicely.

    Then put some wax on it to protect the metal.

    I'm not familiar with the amp but I used to polish up the bumper bars on my dad's car with chrome polish - which took off the rust but left the chrome gleaming - and then apply a few coats of good wax polish to seal the surface. Might be worth a try?

    I agree auto chrome polish is worth a try. By the nature of chrome, these can't be too abrasive. Also wondering about naval jelly -- but it *might* eat the lettering.

    Chrome polish usually has an abrasive in it. I'd be very nervous about that.


    Really, try guitar polish.

    Wax. A little wax might just be what you need to get the surface rust off and it’ll protect it as well. I think anything else (except guitar polish) will take the letters off.

    Your amp is now reliced… enjoy!
    A little chrome polish would clean up the chrome I think. Silkscreen is pretty durable actually. Give it a try in a small section.

    I wouldn’t clean off surface rust unless you have a plan to prevent it as a light surface rust is actually preventing further rust at this point, and it’s basically maintenance free unlike oiling it up.

    I don't know if you get it over there but Solvol Autosol is pretty good and not too abrasive.

    Try some Coca Cola. With only small amounts of surface rust put a little on the rusted parts and let the corrosive nature do its thing. That would be Your less abbrasive option. Once you get it clean out a little car wax and you will be good.
    Also don’t convert that to a tube. I have one and I have to tell you since I opened the back panel it sounds almost tube like. For a SS amp it will suffice for a grab and jam amp.

    And if you have never played it as a head through a 4x10 cab. Try it!!

    So true, mine sounds tube like too. it's also very scaleable in volume for very quiet late night jamming -- plus it has a headphone out jack!
    I have 5f1 clone with a Jensen 12" speaker which also sounds nice, but there's a lot of volume involved.
    you gotta turn it up a bit.
    no silent headphone-out availlable either.

    Guys!...Guys!....what are you talking about?.....Coca Cola, CLR, guitar polish?....this is what WD-40 is great at. Use WD-40 and #0000 steel wool (gently) and it will take up light surface rust and won't harm the silkscreen lettering. Trust me!...(besides, it's not my amp) :)

    Car guys use crumpled aluminum foil and plain water. Alu is softer than chrome and harder than rust; the only abrasive is the micro fine alu dust that floats in the water.

    I've used bar-keepers friend to great avail on an amp chassis I was selling that had light surface pitting/rust. It worked like a charm. You probably have some under your sink. upload_2017-11-9_22-55-8.png
