Fridays are the days to hit yard and estate sales if one has the freedom
to do so. I just scored a Tekronix 2215 60Mhz scope in pristine condition with all manuals and two P6120 passive probes for $18. And with just an outlet adapter or Aussie cord, it'll work down under. Now all I have to do is learn how to use the darn thing! On the way home, found another yard sale and scored a 320Gb external USB HDD in original shrink wrap for $10. Jon |

Check on eBay, they seem to sell between about $50 and $150. Have a friend that does some real high end power supplies for scientific instrumentation that is going to check it out for me and make sure it's in good working order. And give me a quick run down on the basics. Jon |

Funny thing too, is that outside of the scope, the closest thing to
tools was some old school drafting stuff. I was about to head back out of the garage when I spotted the scope, packed with manuals, in a clear plastic package like what bed sheets come in. Jon |

Congrats, Jon, unless it was "only dropped (3 stories) once". It really and truly looks brand new. Not a trace of dust in any nooks and crannies. Plugged it in, and get 'blips' running left to right, so it's at least somewhat functional. I have no reason to believe it's other than pristine however. Will be getting it checked out week after next. And another score today. After winning $96 on the Lotto last week, and yesterday's scores, thought I'd hit the road today. Hit 10 yard sales all over hell's half acre today, nada. Until I hit the last one, where there was a set of Spikes Spiders, the replacements for snow chains you just clip onto a wheel adapter. They are bloody expensive. Only chains that will fit my Escort are cable chains and I -hate- them, as the rollers just want to, well, roll under the tire. From the size of the vinyl carrying case, I assumed them to be too big for my car, and wondered why nobody had bought them yet. Well, the zipper was buggered making it impossible to open. I did a bit of groping, and determined there were was a set, and gambled on the purchase, that I could resell and make some money. The cost? $3 Get home, and boy-oh-boy, it looks like they will fit my Escort! WooHoo! I guess I'm just getting to be a pussy in my old age, but crawling around on hands and knees in the snow chaining up sucks. Receipt shows they were purchased from the guy I get tires from and I'm due for rotation, so will have him do whatever it takes to properly fit them up. Jon |

Today...
Bought a pintle hook adapter for $5, similar to this: http://www.amazon.com/Buyers-Pintle-.../dp/B0000AX57E I needed it badly to tow that M105A2 that I won in the miiltary auction. Very happy about it. K.O. Lee valve grinder for $40, like this: http://ef.algebra.com/e/360254563637 but with a big box and a bunch of accessories. Super old phonograph with some kids music included for $15. This might not work and I may need to throw it out. Prestolite torch, a bunch of Victor tips including a #6 rosebud tip, Turbotorch, lots of igniters (most thrown out), propane torches, etc for $20. i |

If it is old enough, the most likely failure will be the spring which drives the turntable. (Wind up style.) The other thing is you will need some consumables (needles -- cactus needles work nicely -- steel ones have to be replaced more often or they start to grind away the music from the grooves. Of course this is purely deadly to stereo recordings. :-) But the playback is purely acoustic -- no electronics or electrics. Be warned -- the spring is a flat clock spring type, but 1" wide and thick -- a killer if it gets loose. Usually, the failure is where it hooks to either the center shaft or the outer cage, and it is possible to make a new hole at the cost of some play time by shortening the spring. Later -- you would find electric motors turning the turntable, but still an acoustic playback unit -- especially on kid's phonographs. Most likely failure here is the rubber tire which transfers motion from the motor shaft to the inner rim of the turntable. Then we get to electric motors and tube amplifiers. Tubes are the major failure mode here. Needles get a bit fancier -- but are only sometimes called "styli". Then to solid state amplifiers. Back to the needle/stylus and the drive rubber as the most likely failure modes. There is *one* out there somewhere -- built from a kid's portable phonograph to demonstrate a flexible mosfet power transistor printed on a mylar film. Full power for the amplifier was a single 1-1/2 V D cell. The speaker and the cartridge were hooked directly to the power mosfet. It was stolen from the research scientist's car, and he looked forward to the time the battery died and the thief took it in for repair, and the repairman would say "You have *got* to be kidding me.

several incorrect statements in Don Nichols review of phonograph technology
on older wind up units, the failure I have seen most often is hardened grease - it won't work because it's all glued togethr - clean and it's fine on tube units, most common failure is one or more capacitors, "DoN.

The problem is that the arm holding the needle seems to be a little loose and not balanced by any kind of a spring etc. It feels wrong. I would expect it to come down on the disk gently and to be relatively stable. I may post some pictures and a video. i |
