[sdiy] tuner

[Rude 66]

hey magnus,

 i don't know about resistors, man.. they're scary.. all those colours.. ;-)

that doesn't sound like too much trouble. unfortunately i don't have any
schematics, but it's a lafayette lt78-c, looks like late 60's early 70's
design. is there a component or label i should be looking for on the board
to try and find the audio input? i have to clean this up first, there's so
much dust inside nothing is readable anymore..

thanks!

ruud
