  • Kirsten’s Marantz 2010 Restoration

    I love these baby Marantz receivers so when this one was shipped to us for restoration I couldn’t help but take a few pictures. The 20xx series are built on a smaller chassis and are much more compact then the typical 22xx or 23xx receiver. They are Japanese like their big brothers and are usually […]

  • John’s Luxman L-507 Integrated Amp Restoration

    This is a rare amplifier from Luxman and was one of the finest pieces of audio from Japan in the 1970’s. The amp is in near flawless condition but was suffering some of the issues that come with 40yr old parts. The owner was describing distortion in one channel and on arrival we noticed a […]

  • Linn Lingo Turntable Power Supply Restoration / Upgrade

    One of our technicians purchased a Linn LP12 which came with a Linn Lingo external power supply. This unit being from 1990 and pushing the 30yr mark he decided to go ahead and swap out all the electrolytic capacitors in the power supply. Linn used high end parts in their gear and the new components […]

  • Dynaco Mark III restoration and modification

    Recently we had an original owner pair of Dynaco Mark III amplifiers brought to us for restoration and modification. The amps had been serviced recently elsewhere and the work done was trivial compared to what was actually needed. Both monoblocks had their original multisection can capacitors, tubes, coupling capacitors, and still utilizing the selenium rectifier […]

  • Rick’s Pioneer Spec 4 Power Amplifier

    It was a pleasure to do some restoration work on such a nice top of the line Pioneer power amp. This SPEC 4 amp was sent to HV HiFi from Virginia and on early visual inspection we found venting filter capacitors. This has been becoming the norm for many of these big amps from the […]

  • Rich’s Marantz 2285b Receiver Restoration

    This Marantz 2285b was flown in to HV HiFI for restoration and is a wonderful candidate. The entire dial lighting is out which will be replaced with our warm white LED package, and the normal component replacement on the signal path boards done. These are “dual power supply” receivers made in the late 70’s and […]

  • Ed’s Sansui 6060 Restoration

    This Sansui 6060 was purchased by Ed and he wanted the unit restored. After the work I’m glad he did since the receiver sounds as great as it looks. First up was the amplifier board. New Panasonic capacitors, low leakage caps replaced with stacked film, and bipolar caps replaces with Nichicon ES. The two pairs […]

  • Bruce’s Marantz 2270 Restoration

    Really happy to bring this poor 2270 back from the dead and then gave it the works. Receiver arrived completely dead blowing the main fuse. Powering up on a variable transformer it was drawing close to 1A at 25vAC. As expected shorted outputs on both sides. This unit was a 14xxx serial number so had […]

  • Doug’s Sansui 881 Receiver Restoration

    Just finishing up this excellent Sansui 881 that is a very well built piece of equipment. These receivers preceded the x0x0 and G series Sansui but I feel are every bit as good if not better. There is a large board next to the power transformer in which the power supply and protection circuit reside. […]

  • Sandy’s Marantz 3300 Preamp

    Another great piece of Marantz history a 3300 preamp. This unit has a power supply mounted in the middle of the chassis to the bottom plate and three boards that have pins to connect to the main board running behind the faceplate. The pins should be cleaned well and lubricated to remove any oxidation and […]
