    Technics SL-1600MKII Manual Arm Lift Lever Issue

    Hey all, I have a SL-1600MK2 that has a lingering issue that I would really like to correct. The manual arm lift lever does not properly lower the arm after the lever is returned to it's down position, it only goes part way. To get the arm to lower fully, the lever must be moved slightly up...

    Howard County MD Hamfest is this Sunday May 30th - Anyone else going?

    I plan to be there and will setup a table if anyone wants to stop by and BS. I plan to bring lots of cheap CDs and whatever random gear that needs to find a new home. I know there are a few of us that usually go to this event and figured I would post this as a reminder. It will be a tailgate...

    Hey Altec and JBL nuts, Was cleaning the basement a little this afternoon and decided to box up some Altec stuff to make it stackable, which lead me to finding this... After removing the driver from the horn I heard a faint tinkle noise and popped off the cover. That certainly explains...

    Carver M500t faceplate reproductions - thoughts, comments before I buy...

    Hey all, I have a Carver M500 that has a trashed face plate with scratches, deep dings, and the silk screened writing under the Plexiglas lens is nearly washed off from water damage. I've had this amp for many years but recently decided to get it working to see how it would push my Shahinian...

    Bracing Altec 825/828 horn flares and cabinets

    I'm working on a pair of Altec 825 cabinets to get them sounding better and just started looking at bracing the horns since they vibrate like crazy during frequency sweeps and during midrange heavy passages where the music sounds congested. This pair of cabinets are constructed from ¾ ply and...

    I forgot how heavy MDF and particle board can be.... Altec 9844A

    I picked up pair of 9844a a few weeks ago and haven't had much time to play until the holidays. I gave them a quick visual the evening that I brought them home and they looked good and measured generally as expected given that the crossovers were modified. Getting the cabinets into the car and...

    MC-30 Can Capacitor

    Looking for some input, I just recapped a dead MC-30 and had a CE 100uf/100uf 500V cap laying around that I used to replace the old unserviceable can. I fired it up and the voltages look good but the rectifier is quite noisy. After thinking about it, I am a little concerned about exceeding...

    Nytone NS-4000 Integrated el84 amplifier

    I picked this up locally from a buddy a few months ago and I'm just getting around to planning out a quick refresh as it has a bit of PS hum and sounds a bit thin and distorted. The amp clearly has had some work done but they left the selenium rectifier and some older caps that will be the...

    Repairing output transformer wires with damaged insulation - Seeking advice

    Hello All, I'm working on a Fisher 400 that had a tube go nuclear at some time turning the 1.2k resistor into a fire bomb. Someone had replaced the flamed out resistor with a new one before I received the unit. I ohm'd out the transformer and it matched the readings from the tranny in...

    Woofer cone repair options on older Philips driver

    This woofer is a 15 inch Philips out of a Heathkit 1348 speaker. At some point in this speakers life, the paper cone was damaged around the area where the voice coil is glued in. I have no history on the damage but found it while diagnosing voice coil rubbing noises. I've attempted to...

    Fisher 800b bias issues

    Morning all, I wired this up last night and quit working on it after I had a smoking 15 ohm 6.5 watt resistor while I was beginning to check voltages with my meter (on the dim bulb). I powered it down and left it alone until this morning. I went back to the bench to check it out and take...

    Looking for an audio rack wide enough for Sansui G8000/9000 and Pioneer SX-1250

    I'm in the market for a new audio rack for my main setup. So far I have been unable to source a rack that will fit components that are just over 22 inches. The large majority of racks will fit this size component on their top shelf only and that is where I prefer to place my turntable that...

    Another Denon Dl-301 II Problem, it fell apart...

    When to listen to some tunes yesterday and was greeted with a dl-301 II that looked like a road kill in rigor mortis.... My first thought was the cat, but then it dawned on me that the dust cover has been on the table with the same LP that I left there days ago, and I rarely leave it off due...

    Hello Kenwood gang, I finally found a Kenwood integrated to match my KD-750 turntable that I restored a few years back. A few weekends ago I found the 907 with the KT-815 tuner at a flea market hooked up to a power inverter off of a beat up truck jamming Van Halen on the radio through a set...
