well another ex-auckland pick up and have not powered it on and wanted to check and clean it out first.. not a bad set of cards inside as well.

removed the cards and then the base board as like the other the shields were rusty and i need to clean them up..

so after getting the main unit out.. what a hassle to get the thin tin shields off the board..(well the top one) then there is the lets solder the switch on.. so you cant get it out option... ahhhhh.. well it's frozen like all the others so snip/snip...

then taking off the top shield and turning it over i see someone has been playing with it.. and cut and re-soldered tracks.. the shields are rusty top and bottom

so after a little elbow grease i cleaned the top and bottom case shells inside and out.. got almost all the rust stains off the inside.. and it looks a lot better.. as with the others i'm waiting for the nickel to re do them as well..

ok.. so waiting for the Nickle to arrive and while it crawls its way here i did the rust removal on the bad metal parts.. they came out a lot better than i could have hoped for..

the above were the before rust removal was done.. the below are after rust removal

after a quick clean in the sink with warm water and a dry with paper towel's i put them in the overn on 100 deg for about 15-20 mins to make sure they were dry.. i did try to electro plate them with nickel when it arrived as in my electro rust removal blog but it didn't come out that good ... well not to what i would like so i rust painted the main parts. where there was electrical contact i left the original chrome and didn't paint it..

the only part i did paint was the top cover for the 601 cartridge cover.. that i did in primer and then silver paint to make it look a little more original..

now to put on some push connectors and a new plug as these were soldered on so you could not replace them very easy..
