content: In this video we tear a Eico model 315 signal generator down. This was one of the items from video #29. We will take a look at the problems, disassemble and do a little cosmetic work.In part 2 we will test and replace faulty components and align the unit.See more pictures at:http://gokarters.com/smf/index.php?topic=2538.msg18255#msg18255Manualhttp://www.kevinchant.com/eico.html

content: Nice job! by the time you finished it looked like new.As for the TS-520 video, run it, not everyone has to sound like Walter Cronkite and the technical content is more important than the odd cough or sneeze.

content: Quote from: German_EE on March 06, 2016, 01:59:00 pmWas really surprised to see it look as good as it did. Have to get the case primed today before it rains again. Think I will use this piece to inject missing IF signals from old tube gear.Working on editing the 520 videos now.Thanks for commenting.

content: Nice video. Love that old gear. I am working on an EICO 214 VTVM (with a 7+inch meter face!)I usually don't turn on those old units with those wax cap in them. Always afraid they might damage something. I typically replace the caps first.I have learn to check meter movements FIRST on old meters. I wasted a lot of time restoring another EICO 214, only to find it had a movement beyond repair. Of course it was good practice for this one, and I am able to share parts now.

Things go bang in a hurry.I brought this one up on a variac with a current limiter when I first got it. Very surprised that the old caps still check good after all these years.Get lucky some times I guess.

content: Nice video as always, pleasantly surprised me with cutting to the clean up. A pretty case inside, you wouldn't believe it from how it looked outside, most of the times it's the opposite. I'm thinking about old gear I passed on now.
