Rob, The best place for help with the 7603 is the Tekscopes group at yahoo. I have a tek 7603 myself. I got it at a Junk yard 24 years ago and it still works very well. I only had to clean it. It even came with the cover :) One of this days I will open it to clean it again. |

Most amazing results! robrenz procedures should be of help to all, the photos show it all. I've highlighted the key equipment used. --- Quote from: robrenz on December 16, 2012, 08:20:07 pm ---The main cosmetic issue was serious corrosion under the nickel plating on the front and rear frame bezels. The main covers were just dirty and needed some body hammer work from heavy items that gently bowed the tops in the perforated areas and some light dents. Magic sponges and simple green were extremely effective at removing the dust that very firmly attached itself to everything. Armor all was used on all the exterior plastic and vinyl parts. The plastic CRT filter needed a wet sand and plastic polish treatment to remove some mild scratches. The main functional issues were the very dirty and corroded bnc connectors and the normal scratchy pots and switches. I disassembled the pots that were bad and ultrasonic cleaned all the parts in IPA. Then cleaned all the contacts and wipe areas with Deoxoit D100L on a soft wood stick. Clean with IPA again and lube the gold wipe areas with Deoxit G100l and the actual pot wiper with Caig Faderlube. The mechanicals were lubed with Triflow grease. The gang switches were flushed with IPA and then Deoxit D100L was blasted thru them with compressed air. The drum switches in the amplifier and timebase were disassembled and all the gold finger contacts were individually cleaned with D100L on paper pulled thru the contact area, cleaned with IPA and lubed with G100L. I also replaced the power cord that was pretty stiff. --- End quote --- |
