I brought this up before but it was in SER. Now I want the real gurus because I got a brand new plan. (kinda like Steve Earl - Copperhead Road, but I am not talking about THAT idea)
So I got one of them arm lights. I need about four of them but... Anyway, a while back I found that a CCFL bulb in there wreaked havoc on anything with gain. Seems like everything has gain.
So I replaced it with a halogen I had laying around. Normal socket conformant to the usual light bulb specifications. No more 35 KHz in everything. You should have seen what it did to scopes.
The problem now ? What am I yammering about ?
IT GETS TOO DAMN HOT !
So what I wonder now is just what do I have to put into a CCFL to get it to light ? I am willing to take one apart and rework it, and build a nice clean (EMI etc. wise) DC power supply for it.
Also remember I said I need like four ? So the next question is if I can use one power supply for multiple lights. Will that work or will they act like neons where only one of them in parallel wants to fire ? Or should I up the voltage and put them in series ? Would the load be balanced enough unit to unit for that to work ?
If I get something that really works hell I might start selling them. When I make the first hundred grand everybody here gets a 12 pack of beer. Or maybe the finest locally grown, grass fed filet mignon. Or maybe a couple of my special pork chops with rice. (usually it is BYOR - Bring Your Own Rice, I can't cook rice so I have to use the boil in the bag stuff, Ma tried to teach me how to cook it but I just don't get it, like when do I put in the 15 tablespoons of garlic powder ?)<not entirely true, I prefer to use fresh garlic and usually do...
Now, since I know this thread will be hijacked I might as well just do it now. You wanna go to Cuba or Libya or what ?
Anyway, I am not so sure resurrecting Thomas Edison would work though he was pretty fart smeller. Actually yes, he advocated that instead of borrowing the government should just print the money and take the losses, rather than be enslaved to interest payments.
The fucking liberals and their green shit. You know how hard it is to even find a bulb for my DBT ? These newcockfahglred fucks DO NOT WORK for that application.
Which brings us unfortunately for hijackers to a very related subject. The fucking green asshole liberals got it where sooner or later there will be no incandescent bulbs for sale at all.
I NEED a DBT. I work on high power audio and you NEED it. With the dynamic properties of the DBT it is perfect for amps. If nothing is shorted then the lamp is...dim. It loses almost no voltage on many amps at quiescence. See I am like, I mean I am THE person you want working on your mp and I am starting top get quite the reputation for it. My testing procedure is so fucking tough it has to be adjusted for each amp that crosses my bench. when I fix them the stay fixed. Let's put it this way, had an MCS in last week or so. threw in pair of outputs and all went well, OK. Thing is for this 25 WPC amp I put in MJ15023 and 15024. Seriously, the power transformer doesn't have the balls to blow those. The only, and I mean THE ONLY way to fuck them up is to get it up to a high temperature because as we all know everything needs to be derated on dissipation. You can have a transistor that can dissipate 200 watts, but what can they do at 170ÂşC ? It almost doesn't matter what transistor you got then.
It amazes me sometimes how much bullshit people go through to get output transistors. I KNOW what the ideal transistor is for almost any amp, and why. You want a good audio output, those MJs have a fairly flat HFE/Ic curve which is important for a high quality amp. Bandwidth is more than they'll ever ask.
Then for the flat pack I just go with 2SC5200 IIRC and its comp the (IIRC) 2SA1941. Also, and I ain't telling, I got a source for transistors like the 2SC2922. My source comes up with some hard to get ones, seems like some MF with money bought every semiconductor type ever made and sat on it for 30 years. The only ones I can't deal with by a retrofit are those Panasonic/Technics SVI type STK outputs. If I used normal techniques on those Technics they would not really be what they were anymore and that is not what I am selling.
Know what kinda scares me ? I have in a Flame Linear 400-2. Blown channel. It has been improperly serviced, the banks of outputs are totally mismatch in both channels and the client is going for changing them to a matched set in the working channel after I explained why I recommend it. But the scary part is IF the shorted outputs destroyed the current limiters - they are germanium. One day I might be in here asking how to adapt it to silicon. Look at the print and you can see it is easier said than done. It is the typical dual slope thing they got running off the Re s. But to meet the silicon threshold a bunch of circuit values have to be changed. Luckily though none of this affects the sound.
Many people LIKE the sound of their amp even if it isn't perfect. I understand. My bench receiver, bench - I mean I use it as a source for amps sometimes, or as a power amp for preamps, you might think of it s a simple utility. But I like the sound of it. It used to be a Pioneer SX-850. Been through hell, both a fire and a flood. Regulator board broken in three places. Also had a blown channel and the bias pot lit up so that is gone. And then in the preamp something happened and I never figured it out, partly because I didn't want to take the front of that apart. So I got a couple of 100K resistors to set the bias, it was clipped to the point of no sound. The glass in front is broken, the shaft for the tuning knob is bent. The regulator board will never be mounted again. I do not have the top or bottom covers. One metal sheath is off on of the switches, but I actually have one ! I just ain't putting it on this.
I got a problem with pictures on the net right now but I would gladly post a picture of this thing. You would say "What a piece of shit" until I turn it on. My real dilemma is that I want this stereo out in the garage AND down in the basement. And I need a PC with a good soundcard that will connect to the wifi so I got access to my media library. (there was a time I had a projection unit out there throwing at the one garage door, 3,500 lumens)
Now if that hijack wasn't enough...
You know I am almost ashamed to ask you guys shit. You are mostly so above me in knowledge of the subject I have very little to offer. I have come up with a couple things via omnidirectional thinking. (remember lateral thinking ? well this is that on steroids)
But then I could think of it a different way. You helping me is dues for having someone to call fucking stupid and crazy and all that shit. What - you thought that was free ?
So anyway, be well, have a good time in life. Find humor in life. I am mastering that. You put me in front of a TV I am NOT going to STFU. I mean some of the hapless folk I would never joke to their face because it would upset them and I have no reason to do that.
But without their presence... Take the show "My 600lb, Life". Here we got a broad who can't get out of bed even because she weighs 550 pounds. And gaining.
Now I am going to tell you one tenet of physics that people just do not apply to - - - whatever.
There is one FACT. When you are born you are what 8 pounds. Now you are maybe 200. Where the fuck did those 192 pounds come from ? Well your weight IS the EXACT amopunt that you ate, drank or got infused or the fuck whatever, subtract all you excrete, shit, piss sweat are the normal ways unless you are a cutter or some shit. (buddy of mine has a GF does that, she is moving out this month or next)
You could say, if you accept that mater is actually energy just formed right, then the law of conservation of energy applies to matter. That means you are what you eat, there is no fucking doubt.
Anyway I got into those shows a little with Ma, she is old and watches that and I don't mind spending a little time with her. I upped and said "What were these people thinking when they were 500 pounds, 400 pounds ?". I haven't pulled this one out on Ma yet but...hit that bong...
Now this broad can't get to the kitchen or anywhere. her boyfriend brings her five Big Macs and a few supersize fries. Now if he is connected to her and "loves" her, you know this is like giving an addict drugs. Overeating is one of the fucking hardest things to beat. Coke, booze, whatever, you can stop completely. (NEVER say "quit") You cannot stop eating.
LOL. Is this hijacked enough ? I wanna see somebody outdo it. This plane already landed and I got Castro on the phone. I go pick up my money tomorrow and luckily I got my gun. Can't fucking trust anyone in that kind of business. Yeah that few months of aerospace in school paid off. Only blew one tire landing and they got a spare !

Put paper on one it lights up quick.
