OT: cleaning pots on my vintage audio amp

by acme_ent＠bellsouth.net

> From: Chad Fernandez <fernande(a)internet1.net> After posting I realized that I neglected to mention that the humidity here in Florida most likely contributes to the problem. > Tuner cleaner? Okay, I'll look for it at Radio Shack. I don't know > else where to look around here. Also known as "contact cleaner." MCM sells a dozen different ones, including Rawn Contact Cleaner at $4.99 for the 9 oz. can. Or, you could visit a TV repair shop and ask if they'd sell you a can or two. I use a lot of the stuff as it works well for cleaning the contacts on computer expansion cards and slots, etc. > Your speaking of the line level connections? Yup, and the headphone jack if there's one present on your amp or other device. > I for got how heavy this monster is..... it's got to be about 40 lbs!! Yeah, my Fisher 404 quadraphonic tuner/amp out in the living-room contains massive transformers and is *not fun* to move. That sucker really rocks, though -- I can't turn it up much past 2 1/2 and still stay in the room ;>) The AM tuner's starting to drift so I'll have to deal with that some day. Glen 0/0

Tandon TM100 (was Destructive charities (was: STAPLES STORES...))

by mhstein＠usa.net

Oooh,Oooh!!! <Jumping up & down 'cause it's the first, and no doubt the last, time that I've got a manual that Tony doesn't> I'VE got a TM100 Technical Manual !!!! (and a pile of TM100's, although not many, if any, to spare). In fact, I recently sent someone scans of the three main schematics, so if anybody needs 'em, no problemo, still got 'em (tif format) A popular source for stepper projects, and there are quite a few tech articles on the web by people who've built camera & telescope mounts, etc. with 'em & interfaced to printer ports. mike ----------Original Message------------- From: ard(a)p850ug1.demon.co.uk (Tony Duell) Subject: Re: Destructive charities (was: STAPLES STORES...) > > and the schematics are easy to get. > > Oh? Now that would be a help, where from? IBM Options and Adapters TechRef, TRS-80 Model 3 service manual. To name but 2 manuals I have that contain said schematics. I guess there would have been an official Tandon service manual, but I've not seen it (yet).

Average lifting weight

At 12:12 PM 2/19/02 -0600, you wrote: > >My question is, does anyone know how many people it takes >to lift this comfortably? The amount of allowable lift weight has gone steadily down. When I was in the USAF (mid '70s) it was 75 lbs for a man. It's since been lowered to 50 lbs and about 10 -12 years ago was lowered again to 40 lbs. I'd say that you'll need *at least* six big strong guys. If they're not big and strong, you'll need up to twice as many. Joe

Radio Shack

by ceby2＠csc.com

If you go motoring in the DeLorean, just remember to bring heavy weather gear. DeLoreans have many less than admirable qualities to compliment their geek-appeal. They leak from every passenger compartment related gasket and seal -- especially the windscreen. They have the go of a Volvo wagon -- because that's where they got the engine (not that this was such a bad thing in 1981-2) just don't try any Porche slaying. They also have unreliable cooling systems. This has nothing to do with the location of the engine. It's because the radiators up front and the lines running back to front corrode with breath-taking speed and performance.... almost that of a Volvo wagon. I became overly intimate with the long dead marque, when a flatmate ( full time truck mechanic) took such a beast on as a side project. It haunted the driveway for six months, making it damned awkward to get my Kawasaki in and out of it's paddock. Can't say he ever had a kind word for the stainless steel lawn ornament. He was just glad someone was giddy enough to want it fixed up. The DeLorean's owner got well and truly milked. My flatmate used is ne're do well gains to got well and truly sauced. I can, as a result, say that if you wanted to get a computer into a DeLorean -- you'll require the upgraded shink-a-matic ray gun. The standard model would never hack it.

Real computer or not, it is one of the most impressive cars I've ever sat in. One of my geek friends owns one, and has promised me that the next time he runs it He'll give me a ride. I have every hope of upgrading that ticket to a chance to drive it. Just getting in the driver's seat is sweet. In the immortal words of my auto-dealer grandfather, "It makes yer butt laugh just sittin in it!" Doc, who didn't see any straw-holder either.

STAPLES STORES WILL TAKE OLD COMPUTERS

by mythtech＠Mac.com

>I'd not thought of there being a con trick where you return an >essentially worthless box full of junk for resale (I assume that's what >happened here). I check the contents of boxes in case the manufacturer >made a genuine mistake. And sometimes the manufacturer DOES make mistakes, or at least have packing mishaps. I bought a VCR from PC Richards (actually 6 identical ones, don't ask...). All were fine, except for one... it looked like a car that had been wrapped around a tree. The entire front of the VCR was smashed, and obviously against some round object. The front was rolled back almost halfway thru the VCR... it was actually quiet funny (and I am bummed I didn't think of taking a picture). The box was in perfect condition, and so was the styrofoam shell. Which means the damage occured BEFORE being boxed (with this degree of damage, I would think it would have been caught in packaging... so it might have been deliberate from a disgruntled employee). Fortunatly, the staff at PC Richards got as much of a laugh about the damage as I did... and didn't hesitate to allow me to exchange it for another identical unit (but only after calling almost every sales person over to take a look at it) Ever since then, right before a store sticks that "you opened the box" sticker on it... I slice the boxes open, and give a quick look over what I just bought. (And since then, the local PC Richard has started opening all electronics and showing them to the customer before they leave... I think that was probably just coincidental timing of a company policy however... I can't believe my $60 VCR had any sweeping effects on store policy). -chris <http://www.mythtech.net>

Anybody need a couple of Redstones?

by rigdonj＠cfl.rr.com

Spotted at a scrap place today. Two Redstone computers. They look like Apple IIs. Steve Roberts will be stopping by the place Wednesday. I suspect he can pick them up if anyone is willing to pay him a few bucks to cover the gas and packing and shipping. These are a bit rough. The covers are off and all the cards removed (I dont know if they'll run without cards or not), one cover is there but I didn't see the other. Also some keys missing. I din't dig all the way to the bottom of the bin so there may be moreof them there. Joe

Average lifting weight

by uban＠ubanproductions.com

Generally, taking these large machines apart is the best solution. Then you can handle the individual pieces yourself... --tom At 12:12 PM 2/19/02 -0600, you wrote: >Ok, maybe some people with more experience lifting classic >hardware can help me out here.
