Ricky,

I did a quick search and did not find any information on this transistor. I hope someone else can help. Maybe I should run a contest or something. The first one that finds a datasheet wins something… It’s an idea to ponder.

Do you have any details or knowledge on the NPN 04S49 Transistors? I cannot find them listed or referenced anywhere but this site. I was building a fuzz box and the AC127 and BC108 transistors supplied sounded very poor. I replaced the Q1 with a 04S49 I found in an old electronics stash box my dad had from the 60s-70s. The 04S49 (Motorola logo) tranny really sweetened up the sound of this pedal. I is amazing. Just curious… Thanks -Rick

Sam,

I have made a nice sheet of labels. I plan to do an quick article about them very soon. I will send you what I have in an email. Let us know what you think.

Just building up my parts kit, and realized that labels for each bin with resistor color code + value would be usefull. Can’t believe there’s not one already on the net. If I make one (using the avery template), I’ll definitely publish it.

dfowler, is your label sheet available?

NT7S, I just ordered the Analyzer kit. I suspect it will be the best $70 I have spent recently. I had a simular automatic transistor tester project planned so you spoiled my fun on that…

sysadmn, I made a full sheet of color labels for parts bins which I figured might be a good thing to publish. I was wondering if anyone else had done something simular. I do have some small mailing labels wich I can try.

What kind of pre-made label sheet or a graphics file are you looking for?

I use Avery labels – they’re a little expensive, but they come in many sizes (check out address and file folder labels). If you use MS Word, there are downloadable templates; if you use OpenOffice, create a table with cells the size of the labels, and leave generous margins on all sides.
If you use a graphics program to create your labels, generate a layer that outlines each cell, create each cell, then zap the outlines.

All of these work better if you print a sheet at a time. I use a laser printer capable sheet (http://www.avery.com/us/Main?action=product.Details&catalogcode=WEB01&productcode=5260) and my printers “straight-through” path.

I want some grab bags too:D can you show us some bigger pictures of the mystery items?

If you get seriously into appropriating semiconductors from grab bags and what-not, you might want to look into the M3 Semiconductor Analyzer:

Just hook up the clip leads to the pins of the unknown device, and it will tell you what type of device it is and many useful parameters. The usual disclaimer applies, I’m not affiliated with the company, just an interested ham radio op.
