Most amazing dumpster dive ever!!!!

closest thing i've gotten to a dumpster dive was saving some awesome vintage guitar amps when 2 years ago, after some renovations, my high school's music department was cleaning up and i was helping out. i was going through a back storage room when i came across a 1966 blackface Fender Bassman amp and a 1972 Traynor YGM-3 Guitar Mate Reverb...both are awesome vintage tube guitar amps and the Bassman also does well for bass, which it was originally intended of course, if a little underpowered. they wanted me to get rid of them! of course i "did"...i asked my mom to come pick me up that afternoon and i loaded them into the trunk of her car faster than anyone could ask me what the deal was.

upon looking at them at home, i found all the Traynor needed was a new 3-prong plug, so i got a really beefy one from the hardware store. upon further inspection it seems that it was full of old tubes... Philips 12AX7s and Westinghouse EL84s!!! it is one of my favourite amps ever now, especially since i replaced the speaker. the Bassman came with a pair of RCA 6L6s and a bunch of Sylvania 12AX7s, and needed a new output fuse. i must report it runs flawlessly and with a Tubescreamer pedal and the volume up, it lets me sound like Jimmy Page on "Rock & Roll".

if you want good heat sinks and caps, try finding your local computer recyler.
Ring a data center and ask the manager who recycles their mainframes or look it up in yellow pages. The power supplies in some of these things are good value if you can be bothered stripping them.

I like to call that a "pre-dumpster intervention."

Good thing you knew what they were. I wonder how much great gear is tossed out because no one knows how good it is. Of course, if these things weren't being tossed out, we wouldn't have great stuff to dive for. There's a catch-22 in there somewhere.

Best thing I found was two Altec cabs fitted with 6 Altec 755E drivers per cab. They look minty on the inside and sounded great when fired up.

I really envy those rare Tannoy and VOT horn finds, though. Those are on my "must-find-in-dumpster" list. 😉

Best,

Just cleaned out a dumpster that was full of stuff from an audiology lab, almost started shaking when I pulled out 2 scopes, a BWD and a 20MHz Gould digital storage, B+K mics, a LCD Capacitance meter, sine/squarewave generator, just 1 of the loose pcbs had about 10 OP27s 😀

Also found this self propelled mower ..... The blade was loose , common fault . So it wouldn't start , so dumb rich man throws away . Thrifty wise man takes home , tightens blade , starts first time. Oh and the drive belt had snapped !Sorry this was abit off topic , but im sure this is global if you happen to live in an affluent district/ region. More money than brains ...

Have been looking for old fluorescant light to salvage the chokes. Noticed that the local paper were having there offices refurbished and that all the lights were likely to go. Thought it would be soon, but had to go on holiday for a week. When I got back they were all gone. What a bummer:bawling:

At least half of all I have built has been from dumpster salvage.

I have so far in london had 2 dyson vacum cleaners (both perfect), a samsung 15" tft monitor ( perfect) 2 Arcam alpha 5cd plus CD players from the same shop within a month (really weird i know) which needed work but cost about £10 each to repair. A rotel 5 disc HDCD player which had a slightly noisey transformer , a teac cd player , a Project 1.2 turntable, several 100m rolls of cat 5e (solid core) the list just goes on. Three ibm latops pull from a skip

Countless usable pc's , it has to be said that Londener are very wastful but the quilty of what i have picked up seem to be declining so i think recycling schemes and the fact business cant just throw hardware in the rubbish seems to be really kicking in. Maybe better for the enviroment but it worse for my wombling. Oh well been a good run.

Hi there,
If looking for chokes in fluorsecent lights, you need to look at reasonably old ones as they have all gone switch mode now.
They can be found within the light fixture. They can be used as plate chokes in valve preamp circuits. The bigger ones can be used as plate chokes in parafeed output applications. I bought a pair for 100W lamps for £6.00 each from an old light supplier. These seem to indicate that they can handle 0.9A of current. Haven't tried them yet, but am planning on trying in a preamp and a parafeed amp.

I just went and pulled one. On to the bench, just give me a minute here..... haha.

240V / 40W
DCR 27 ohms

It reduces the voltage on a 10k resistor by 3dB at 2kHz. Predictable effect below this. Above this it rolls off to a minimum at 20kHz.

So, inductance is approximately 0H8 and interwinding capacitance is approx 80pF.

CRAP i missed a FREE pair of Macintosh MC30 amps on Craigslist today!


Apparantly the poor owner didnt know what they had and have been bombarded with emails all day even after they pulled the and and posted that they were gone!

Hell ya i would have left work to go get those! but i didnt see them until it was way too late. A single one just sold on ebay for $510.00!!!



Sigh....
