echolette

[newhallone]

I went to visit a friend to see if he had pulled out his dads old radios he was going to give me ( he hadn't) but he did give me an old bogen tube amp and a Klemt Echolette. the Klemt is a tape delay unit for guitar and voice. It has a bridge rectifier that says Semikron B300 C70. Not sure if its silicon or selenium. It's pretty tight quarters in there if it still works I would leave it if it was silicon. My big question is it's really dirty and dusty inside, A good candidate to hose it down except what about the motor? Can it stand being wet? Of course I would not attempt to energize till fully dry. I really don't want to tear the thing apart too much because of the fine wires inside the unit. I think I can change the caps without a whole lot of problems. Well made German unit but cramped and DIRTY. The dust is thick even in the motor. Break and electric motor cleaner?

First vacuum out as much as you can, especially from the motor. You might have to rig a small end hose to go on your vacuum cleaner hose to get into the tight spots. Then take it outside and blow it out with a can of computer keyboard cleaning "air." Then go to auto parts store and buy CRC Electronics Cleaner, NOT brake cleaner. Used on auto electronics and connectors so shouldn't hurt your machine. Take it outside and set it on a board over the garbage can and give it a bath.

I have a detailing kit that works pretty good for my vac. The dust is that sticky/gooy dust. I wonder how it gets that way? I have crc it helps but that stuff is tough. Looking closer I think with the detail kit and then air it should help the motor out quite a bit. then Ill use my crc with a very small brush to reach down inside.

Nicotine residue? That stuff will glue any other form of dirt together...
