    Covid, RSA, RSV, Flu, cold, 2024

    :rflmao:I used to carpool, did that for 12 years. Other people being sick in the van didn't bother me, but it did bother my boss who rode with us. One of my sinus cavities is deformed from something that was growing in my head for 30 years, it took out the back of my eye socket and reshaped that...

    Covid, RSA, RSV, Flu, cold, 2024

    This cool season has been rough on my wife and I. I think I probably caught Flu, cold and one of the RS things. My wife did too, plus she had a very short, mild bout of COVID. Me, I never became sick enough to stay in bed or feel sluggish. It was all congestion type annoyances. No headaches or...

    Longevity of CD/DVD players..

    Just had this happen to my Japanese-made Pioneer 300 disc. It has low hours on it, and when I asked it to switch discs whilst it was in the process of playing a disc, it jammed and then the disc grabbing arm popped off of it's track. I had to unload over 200 discs, take it apart and figure it...

    Untamed Vintage Pioneer HPM-100?

    Thanks! The sound is far better than before. To me, HPM-100's in stock form become very tiring to listen to after one or two tracks. Now I can listen all day, the clarity is much improved, everything seems more detailed. I will say, the upper range seems "bright", I don't dare turn the treble...

    Untamed Vintage Pioneer HPM-100?

    Some final pics of an installed PCB: Mounted to the enclosure bottom using nylon spacers and particle board screws Interfacing with the original terminal cup required metal spacers to prevent the screws from going too deep into the OEM binding posts, the thickness of the metal spacers is the...

    Untamed Vintage Pioneer HPM-100?

    Just looking at the construction of the supertweeter, I can see it is mostly a gimmick that Pioneer did not put much effort into. All plastic construction. Looks like a metalized plastic film transducer that might be constructed somewhat like a sheet capacitor and is energized by higher audio...

    Just how popular were Bose bookshelf speakers?

    I'll add that Bose "traditional" speakers were still popular until at least the mid-90's. I bought a set of 201's for my Mom in 1992 from Circuit City. I remember at that time, Bose were a solid choice. I believe Bose still allowed their speakers to be in the same demo room/shelves as other...

    Untamed Vintage Pioneer HPM-100?

    Well, I finally installed the "untamed vintage" MAV crossover breadboard into one of my HPM-100 so I could A-B against the original HPM. Sounds way better to me, I could definitely pick up not-so-subtle improvements, harshness was significantly dialed down, separation between similar sounds...

    HPM-100 woofer needs repair.....conundrum maybe

    I ended up paying an arm and a leg for a used woofer in good condition and have since put my speakers back together. I am also building the MV Audio Labs crossovers for them as I really like these speakers. GordonW has me figured out, yes I do have Pendulum in my CD changer, and I also have...

    Is capacitor break-in a thing...

    As a practicing electronics engineer and hobbyist, I'd like to add a few points to these debates about "break-in" of caps. Regarding modern passive components, very few (actually, I can't think of any, besides rechargeable or standby batteries) are actually rated to "change within a few...

    Another thread about Realistic Nova 7B

    A while ago I was able to repair the cabs on my 7B's. Woofers and tweets are in perfect looking condition and check out electrically. I recapped the crossover with new 15uF MPT caps. My previous observation of my Bose 201's blowing them away stands for the most part..... unless I sit directly in...

    HPM-100 woofer needs repair.....conundrum maybe

    Well, I decided to pull the dust cap off and investigate the issue, and I was hoping that it was just the solder joints from the tinsel leads to the VC needing to be reflowed, but unfortunately one of the tinsel leads is intermittently open in the area where it passes through the cone, and since...

    HPM-100 woofer needs repair.....conundrum maybe

    One woofer of my HPM-100's went open circuit. I diagnosed it as the tinsel leads disconnecting at the voice coil under the cap. I really don't want to pick up a new skill set, so I looked around for someone who can repair this woofer. Found a guy on eBay with excellent feedback, but after 48...

    HPM-100 ruh-roh shaggy

    Jamming out to my SX-1050 with HPM-100's today, I noticed one woofer stopped moving. Did some quick troubleshooting, confirmed that the woofer VC circuit is open. Since I noticed it right about when it happened (I noticed the woofer working moments before, I play them without their grilles) I...

    SL-1500 low freq feedback, feet are no good

    I have a Technics SL-1500 that is becoming more sensitive to LF feedback. Even though my receiver has a sub-freq HPF, it doesn't help as much as I'd like. When I refurbed the TT, I noticed the OEM feet are rotted away and likely not doing their job anymore. Unfortunately, the overall height of...

    Are lower EV prices tempting?

    This is like my home power tools. Corded, cordless, air and gas powered are all well represented. Although I use almost entirely cordless at work as we have the budget for the best battery systems (Hilti) possible, as a balance of trade-offs and value, I do prefer a corded circular saw, router...

    Are lower EV prices tempting?

    The main improvement in big box battery tools was just manufacturers finally adopted better battery chemistries. They avoided that for the longest time, they only wanted to use NiCad up until a few years ago. Even then, I have nice B&D and Makita Li-Ion tools, and one of my B&D Li-Ion battery...

    Are lower EV prices tempting?

    As cynical as I am, I do acknowledge that autonomous cars will generally be better drivers than 75% of what I see nowadays. I work in the transportation industry, I see way too much disappointing actions from the driving public. it's ridiculous how bad so many people are. Sometimes I'm not...

    Are lower EV prices tempting?

    I don't know if it's this way everywhere, but in AZ and WA state, you can't even BE in your car when drunk, even if it's not moving, not running, is parked. Only if you have a designated driver can you be in it. So, the laws will need to evolve around this, as EVERY manufacturer currently has a...
