    The curious case of the oozing dope

    I got a pair of Pilot PSV-1s the other day from the thrift. Upon removing the grills(which was no small feat), I noticed that the dope on the woofer surrounds had oozed to the bottom of the speaker and onto the cabinet. This left me to wonder, what exactly did they dope the surrounds with that...

    Is it a sin to..

    So, I recently acquired at pair of beat to snot Mach One;s, the 4029s. Most would think I'm probably wasting my time rehabing them as the list of bads is kinda long, but I like a challenge and can make them respectable if not desirable at the end. As you know, these things are big, bulky and...

    Fried Speakers

    No, not "fried" like in Bud Fried, but Fried as in fried eggs. Have a pair of PSB Image B15 speakers that I picked up at auction, unfortunately I was unable to test them before purchasing. Apparently, the previous owner decided to hook them up to his SX-1980 and crank them(or sumthin') and...

    More of what were they thinking

    Saw these on facebook marketplace - rebuilt ESS - says they sound great but you do need the strap to keep the grills on because the top speakers are a little too big

    Hole in grill cloth

    There is a small hole, about the size of a BB, in the grill cloth of some Optimus speakers I just got. What's the best way to fix it? And No, I can't ignore it. Sew it, superglue? No, I don't want to put on new fabric either as it is nice shape otherwise

    Can't wait to be 90

    I received in the mail the other day the Music Direct catalog and was perusing the goodness in the pages thereof. Thinking, hmmm, I can't afford that, but rejoicing that in 30 years, some of that stuff can be had for a song(but probably not)

    Technics SL-B100 Runaway Speed

    I have an SL-B100 with runaway speed. I did all the standard checks, clean switches, adjust/clean the VR pots, checked solder connections(all good), to no avail. Also to note, the speed selector button broke off when I was changing the speed, - dammit. I then tried jumpering the switch to see if...

    So I picked up one of these the other day, all seems well except the arm lift isn't lifting.

    Ghost in the Machine

    Strange thing, I have a Technics SA303 - was playing off my phone through AUX and when I turned the receiver off, after a couple seconds, it played again for about a second then faded off, if that makes sense. Only happens in AUX, any idea what's happening here?
