Kimberton HAM fest score! Model 2325 Marantz Stereophonic Receiver 1976 vintage. This is a big boy weighing in at over 50 lbs. I've been searching over the past few years for an affordable Marantz receiver with the gyro-tuning wheel on the front as I had a 2226B back in the day (25 watts/ channel)... little did I ever think I would find the flagship of the line (125 watts/channel) at the price point way below the lower powered units, WOW. View AttachmentHeavy duty stuff in there>>> View AttachmentHopefully it works......

Not tested yet. Detailed the interior and exterior. Received (eBay)a new replacement turned aluminum button that was missing for the loudness. Straightened a few of the larger potentiometer's aluminum shafts that were bent slightly.
There is a trick to this as the aluminum likes to snap off of these instead of bend back. Since the shafts are typically slotted, you must slightly insert a flat head screw driver to just fill that gap (not spread it) then gently bend back the shaft with a pair of needle nose pliers while squeezing against the screw driver in the slot. The screw driver in the slot helps to prevent over bending when you grab the shaft to bend it back. Sounds sexy.

Tested and working The FM "stereo" light bulb needs replaced and the speaker protection relay needs a bit of internal cleaning. This thing is powerful as I quickly blew out a 1" titanium tweeter on one of my small JBL studio monitor speakers. No biggy, I'll replace it and put some larger speakers in line haha.

I've got a pair of nice Pioneer CS-G403's I'm not using...

As an aside, because this is the opposite vintage, I recently picked up a bluetooth speaker. I never wanted/needed one, but now with all the streaming options from my phone I thought it was time. I absolutely loath those little "tinny" sounding speakers my kids have and wanted something with good range and low end response. I read/watched a ton of reviews and narrowed it down to two choices, a $300 Aiwa boombox and a smaller Aomais (pronounced "oh my") unit for $60-$70. (I picked up mine on eBay for $60) Being the fiscal conservative (tightwad) I am, I went with the Aomais and I'm glad I did. I'm amazed at the sound quality of this little thing and can't imagine how much better the more expensive Aiwa could sound. It's not too big, simple to operate/pair, a claimed 30 hours play time on a full charge, a mic input for PA use and you can charge your phone from it if needed. www.aomais.com/aomais-go-bluetooth-speakers-waterproof-portable-indoor-outdoor-30w-wireless-stereo-pairing-booming-bass-speaker-30-hour-playtime-with-8800mah-power-bank-durable-for-pool-party-beach-camping-black.html

Been dipping my toes back into the audio hobby and restored a pair of Altec Lansing Model 14's. Re-foamed, metalized poly re-caped and new 10 W resistors in the X-overs. Hooked them up to a '80s Yamaha "Natural Sound" CR-640 (40 wpc) then fiddled a bit with the EQ's on the Yamaha and the X-over.
Oh My GOD! These '70s vintage 100lb behemoths are super extreme accurate and reasonably loud. You can comprehend everything a singer says and even hear them breathing. Musicians appear right in front of you. WOW, a bit hard to describe until you wrap your ears around a set of speakers that sound as good as a 2-3K$ home set.

Well, it's been a minute but I'm still at it. Saw this "pandemic porch pickup" in it's original box for $25 and I couldn't resist. The owner said one channel was out, but I read on the internets that the speaker switch(s) on these were almost always to blame, and in this case that was true. It was filthy dirty with plenty of scratchy controls, but a little elbow grease and a couple LED replacement dial lights and she was looking MUCH better. Still, I felt it was a little too rough for display, so I flipped it on FleBay and cleared enough to cover a couple cases of beer. Harman Kardon hk 590i. At a conservative 45 watts per channel, it sold new in 1982 for $525, which is just under $1,400 in 2020 dollars.

Nice! Always liked the HK receivers, had a 900+ during the height of the quadraphonic craze. An interesting fact is that HK contracted Jim Fosgate (of Fosgate Amps for cars, good stuff!) to engineer the 4 channel decoding for Matrix stereo and SQ decoding to provide excellent separation on converting Stereo and SQ records.

Quad was interesting, but ultimately short lived. I think it was pretty much dead by 1974. I remember when WYSP proudly announced that it was broadcasting in quad, arounf 1973-ish....

I was dealing with it around 1974-75, if I recall correctly. The local CB shop also sold stereos and televisions, and I did an equipment setup for them at some local jazz festive. It was interesting, but since it relied on your specific placement within the 4 speakers it was tough for a group of people to enjoy. Expensive too, which probably didn't help.
