Free: "Wandering box of laser goods" USA only

Well said Isaac!

Box shipped. Tracking: 13122830000025738373
Expected: Saturday
Got 200 dollar insurance for $3.30
Flat rate shipping: 17.45
Total: 20.75

Hope that helps people know what to expect. You get 50 dollars insurance free but the extra wasn't much.

Wow. so much stuff! It only took me a bout half hour to unpack and chose the few things i wanted but repacking was a biatch...I am really not sure how much longer those amps will survive. i took the caps off of one (they werent soldered on) so i could lay it flat in the box (i put the caps back in its bag).

I was pleasantly surprised to see what you all so far have contributed! I got a few things i have been wanting for a while, so that was pretty nice. Bubonic, pm me your shipping address, i will get this out to you sometime next week.

Really sorry to hold you all up, but I don't think i will be able to ship this until early next week Sorry!

Trash bags are great at generating ESD. Laser diodes and anything CMOS should be in metallized ESD
bags.

Woops :/

I may be able to get it out today. Ill try.

Well, I'm sending my laptop into the manufacturer for service tomorrow. I will be without it for three weeks. I purchased a tablet and keyboard which are scheduled to get here a week from tomorrow. So, this will be my last post until then. I'm sure I will be back on the forum within a week. Bye for now.

BTW, I've stocked up on all wavelengths and output power of red laser diodes. Got over 15 in total. I'm sure I'll send some of these out, along with 532nm DPSSLs with drivers, too.

Make sure you get and give addresses haha.

WBS, will do

Hey one step closer! Lol I'm excited to see the goods !

I had put the notebook in there originally to help keep the sig poster straight. Enjoy the free paper :beer:

I was kind of interested in the vacuum tube amp hardware. PM me.

If there are no objections I'd kinda like to call dibs on that vacuum tube amp board. If no one objects I'd like to have Flaminpyro redirect it my way when he gets the box. I'm pretty far down on the list so I'll understand if there are others who are interested who would like to have the opportunity to check it out for themselves.

Thanks,

@Wizard- email me sometimes using the forum email tool so we can discuss the tube line drive preamp. There are some things you'll need to know about it if you end up taking it. I can't recall what tubes it uses but they are a Chinese or Russian new production equivalent to one of the common current drive preamp tubes like a 5645, 12AU7, or similar. It can be modified to accept different tube types pretty easily as long as the pin out is the same (filament heater, anode, cathode, screen, etc). There is a great website you can cross reference tube types to find out what other tubes have the same pin relations. From that you can make a list of tubes you can experiment with. Some are drop in substitutes and others will require a little adjustment to the cathode resistor value. It's a great platform for testing and modifying a simple tube circuit of this kind. I believe it is a zero voltage gain circuit and only increases the current forward (decreased Z-out for driving low impedance inputs like certain amplifiers and headphones). IIRC its a really nice circuit with low odd-order harmonic distortion and a small amount of second order harmonic distortion. It's this second order harmonic distortion that is what some say gives certain tube circuits their "tube like" or "warm" quality. I don't want to wade in too deep here on this topic, there is much controversy on audio forums about this subject. So, if you're not much into tube audio this is a great starter circuit that should prove to offer hours of tweaking fun. You may have more knowledge about this subject than me but I wouldn't assume it. If you're a tube virgin then the best place to plan on using this is between a digital signal source like an iPod or CDP, and your amplifier. It should add some character to your sound system, whether it's good or bad only you will decide.

I've got some old transformers laying around too that would probably work for this. If you need one holler at me and I'll see what I can dig up. You'll need to build an ultra quiet power supply too. I can whip up a circuit on paper for you if you need one, I've got a software program that models power supplies for tube circuits. That and a 50-100k stereo pot and a little wire and some connectors and you'll have a very cool little tube line drive preamp that will be a great conversation piece.

Let me know if you get it!

I think someone calling dibs is the best possible solution.
