I picked up an old Yamaha P2075 pro series power amp for $20 us. It's showing it's age on the exterior, but for $20 who can complain. I haven't tested it yet, but even if it's dead, the case and transformer is worth $20 for building something else. Since this is built with STK paks for the driver section and the output stages, I am going to have to decide it's long term fate.

Peace,

Dave

The last couple of weeks...

I found a couple of "camcorder" cables (4 conductor 3.5mm to triple RCA) for $2 each (less 40% discount) at a dollar store. These happen to be the cables needed to connect up an SB Audigy 2 ZS to the analog inputs of my surround receiver (or to get 5.1 in 3 PCM streams from the 3.5mm digital jack). The cheapest similar cables I'd found locally were $10. This should help stave off the temptation to upgrade to an HDMI receiver and audio/video card for a while for Blu-ray/HD-DVD playback.

Another $2 mini-DIN to RCA cable worked to connect the SVideo output of a DVD player to the chroma/luma input on a Commodore 1702 monitor.

While searching for cables for the Audigy at a local computer store, I was offered a Soundblaster "Live! Drive" that works with the venerable(ish) SB Live! cards, $15. It adds front panel S/PDIF in and out (RCA), MIDI, and 1/4" mic/line input and headphone out jacks. Looking at the board (and studying a block diagram I found using Google books), the headphone output uses a separate DAC that taps the S/PDIF output from the SB Live! using a CS8414. This suggests a possibility of modifying a Live! Drive to work as a standalone DAC.

$7.50 for a near-new "Wade Boggs" Louisville Slugger from the Salvation Army... this is doomed to be cut up to make a metal-shaping hammer. Not very audio, but DIY and noisy. See the thread on metal shaping tools at the H.A.M.B.

MTX Thunder 7801 Class D Monoblock, $75 (but as-is), also from Sal-mart. I haven't worked up the courage to test it yet. Hopefully it was donated by police, not a dead amp that someone tossed into the donation bin.

I didn't buy the Paisley Research "Reference Two" speakers at another thrift store. The surrounds were rotten, but a little research shows these have a respectable pedigree. It's tempting to replace the woofers with 8" Peerless drivers (currently in bad speakers of similar vintage), and turn the old woofers into bass shakers. Any Vancouver Islander reading this who wants to adopt some orphaned Canadian speakers, let me know.

An update on some previous treasures. The Black & Decker electric die grinder worked great after I replaced the power cord, and picked up a couple of cheap used metric wrenches to loosen the chuck. The 15" LCD monitor would only stay on for a few seconds. One power supply electrolytic looked suspicious, testing confirmed it was bad, and I had a replacement left over from the last LCD monitor I fixed, and it fixed this one too. Before final reassembly, I drilled a bunch of holes in the covers to improve cooling.

Went to look at a pair of Altec Model 15's today and wound up with these instead

Tascom PA-30 amps. 60W bridged. Very low mileage, very good price.

Hmmm, me thinks Cal has got a nice tri-amp system started there!
Nice score! Lucky.

Peace,

Dave

My score today wasn't nearly as impressive as Cal's. An 8" Sony active subwoofer.

Just picked up a 8" diameter x 13'5 long piece of plastic piping for $15. I know, I know, what is this doing on diyaudio?! I'm thinking of an el pipe-o variation! Was given a couple pieces of 4" dia, around 6 to 8 ft long, and one 3" dia piece, around 6-8 ft long also. Should be fun.

Peace,

Dave

Nice.

Didn't buy it, but the other day my neighbour landed on my doorstep with a near mint '70's Marantz 2230 receiver, cleaning out some stuff he said--
Not sure where it'll fit in, living in (another ) closet for now!

Glad this has been brought back up.
There's some pics of my 6x9s here
Cabinet - My Photo Gallery
Scroll across to see them all. They sound very nice, now that I've put them on an open baffle (the plastic cab was resonating like crazy, and the grill cut the treble).
And...
Eminence Beta 12A, for my guitar extension cab. The efficiency is matched to the one in the combo, and all is well.

I've been eying up some old speakers in the main hall for a while now. 12"+tweeter, used "before my time". They've got a pair, not used for years, good condition. The only problem is that I don't know who to ask if I want to buy them.
They're the ones with the metal dustcap, by Roamers of Rishton, if anyone else recognises them...

Chris
