>1) Make sure the unit is unpowered. Don't ask me how I know this. >2) Spray contact cleaner on contacts while working them. Yeah. It took a couple of weeks for my eyebrows to grow back after cleaning some powered contacts several decades ago. Lesson learned.

Re: [MBZ] Contact Cleaner
You need a Dim Bulb Tester for this -- put a incandescent light bulb in series with the hot side of the power plug. Unlike a Variac (which reduces the voltage) the light bulb will limit the current, allowing you to troubleshoot without frying anything. The lamp should go bright as the filter capacitors charge, then go fairly to very dim with no inputs and the volume all the way down. if it stays bright or only slightly dims, you have a short somewhere. Electrolytic capacitors have a defined life, and a Philco console is what, 55 or so years old now, or older? All the electrolytic caps need to be replaced -- as they dry out they become resistors (or worse, shorts) and not only do not do what they are supposed to but can actually cause current drains or damage transistors. I just revived my 1980 Kenwood KA-80 this year, at long last, had several blown zener diodes and a shorted Darlington Power Pak output module. Couple of the transistors driving the output module were bad too, and I still have issues with the phono pre-amp I will need an oscilloscope figure out. If you don't have good electronics skills, best to have a professional work on it. A lot of those transistors (especially germanium ones) are no longer around, even on eBay and the dark recesses of old parts supply places. It would be a shame to fry something by accident that's unobtanium, rendering the console useless. ___ http://www.okiebenz.com To search list archives http://www.okiebenz.com/archive/ To Unsubscribe or change delivery options go to: http://mail.okiebenz.com/mailman/listinfo/mercedes_okiebenz.com

Re: [MBZ] Contact Cleaner
It's usually the old, dried up electrolytic capacitors, and they are easy to see - the bottom is usually pushed out. IIRC, you have replaced those in MB boards - the big old console will be easier to work on.

Re: [MBZ] Contact Cleaner
I am also somewhat into old console stereos. I have one I bought at a thrift store we i was about 14. It is a fancy maganvox and as far as I know still works. Have not fired it up in many years. I also have my grandmothers RCA from about 1968 that I used to listen to when I was at her house. I was playing it one time back in about 1991 when it made a loud popping sound and no longer worked after that. She had it checked out and it needed some transistors replaced I believe. She didn’t want to spend the money on it so it’s not been used since. I would really like to get it fixed but do not know anything about replacing transistors and not sure where to find anybody to work on it.

[MBZ] Contact Cleaner
On my truck swap trip with my pops, we picked up a few things languishing in Illinois that we’ve wanted in AZ for quite awhile. One thing in particular is my wife’s grandmother’s console stereo. It’s a Philco. I’m having trouble finding info on it. It hasn’t been energized in probably 40 years, but it works well. All i’ve done so far is take the back off, vacuumed the schmutz out, took some canned air to it. The tuning for the FM is a little staticky so i suppose contact cleaner is in order? Do i just unplug it, spray as many contacts as i see, let it dry overnight and try again tomorrow? I’m going to get a new needle/cartridge, even though Queen News of The World sounded just fine. Good source? Oh, my new 2005 Dodge 2500 SLT 4x4 Cummins 5.9 ram like a scalded dog...after I got after it in the mountains...Eye-talian tuneups galore. 24mpg , took it up over Wolf Creek pass, didn’t miss a beat.
