    Boston Acoustics A100 speakers

    Well, I kinda been slowing down on the vintage stereo front. However, I sold the HD8 and A60, picked up a set of A70, another set of A150 (that I then gifted to a friend), and most recently a pair of VR970's for the theater room. These have all needed repair too.

    "Custom" subwoofer

    Yeah, before I took a close look at the driver I thought there would be 2 voice coils, an upper and a lower. It appears that they are connected together with only 1 set of leads to connect to. Made it easy! Hopefully my Bose 1800 amp will have enough power for it.....

    "Custom" subwoofer

    It's an interesting driver where there is an upper and lower voice coil that is used in an attempt to lower distortion.

    "Custom" subwoofer

    Hi all! I have an old Velodyne HGS10 subwoofer. The amp is shot, which seems to be a common problem even after the amp is repaired. I am attempting to make use of it with an external amp and a Minidsp of eq'ing the low end roll off. It has a dual voice coil setup in a push pull configuration...

    Nikko Alpha 440 repair with schematic

    Well, if it's super important to you, one could always PM the poster and ask what's up.... Things get in the way, such as life, new stereo equipment, family, etc. Anyways I took it in for repair and it was (I was told) a bad op-amp. Replaced and she works like a charm!

    One headlight out

    It was told to me that they use 1 headlight on low beam for safety reasons. 2 headlights illuminated close together (like on a motorcycle) may fool some drivers that it's a car that seems farther away. At least that's my understanding...

    Wonder Chems (D5 & F5) Deoxit

    I'm glad the deoxit worked out for you. I do think that the d5 and the f5 are both intended to be used on the pots and switches, not on transistors and circuit boards. We have a sticky here that reviews the proper use of deoxit and such...

    Completely rebuilding the cabinet on a Yamaha 1020...Foil Tape?

    My guess would be something like a heatsheild to protect the wood from hot components beneath. Probably don't "need" it, but wouldn't be a bad idea to replace. You could probably use some HVAC aluminum tape.....

    Yet another "I love my SX1010" thread

    With the lists available here, and if you have the ability to solder, why not refresh it yourself? I had one that the faceplate was in OK shape, but the case was missing a big chuck of veneer. I rebuilt it and was happy to have a rebuilt, reliable classic that sounded amazing, regardless of...

    SX1010 Transistor subs on 2 boards

    Awesome, thanks so much!

    SX1010 Transistor subs on 2 boards

    Hi all! I have a SX1010 that I'm in the process of refurbing. I've been using the rebuild list that is available here and it has been an amazing resource. I had one before that I sold foolishly and have missed it ever since. I have a few substitution questions as follows: On the muting...

    SX-1010 Dimmer circuit

    As always, it pays to do your research. Checking at the fuses, I had the correct voltages. When I got to the dimmer board, I was missing voltage at pin 1. Did a continuity check between the fuse pin and pin 1 on the dimmer board and it checked ok. I ended up finding that the fuse holder was...

    SX-1010 Dimmer circuit

    I have a 1010 that I've been bringing back from the dead. All I need now is the STV-3H I ordered from germany. For the meantime, I'm using one I made following others instructions using 3 uf diodes in series. Anyways, The hi/low/-20db, selector, and stereo lights aren't working. The dimmer...

    SX-1010 and the STV3H for bias compensation

    Yeah, I realize that the voltage didn't test right, but it was higher than the 3h that I also tested, so I assumed 4h. I think I'll order some thermal epoxy and give the diodes a shot. Hopefully it will work out...

    SX-1010 and the STV3H for bias compensation

    I have a SX-1010 that I bought (actually a 2fer deal) that didn't work. Upon opening it up, some work needed to be done (some to repair work already done). My question is that it has a STV3H horshoe diode attached to the right channel heat sink, and what I believe is a STV4H horshoe diode...
