    Harman Kardon Citation I - To Mod or Not To Mod?

    Fate has blessed me with two Harmon Kardon Citation I tube preamps. One was beautifully built but also "well loved." The other was drastically modified over the years and is missing a lot of original parts. The "well loved" unit had a pretty messed up face plate, broken balance pot...

    Nice inexpensive experiment, great results

    At my cabin I have a Panasonic SA-PMX9 micro stereo system that is a few years old. These systems were fairly good and fairly well reviewed at the time they came out (https://www.whathifi.com/panasonic/sc-pmx9db/review). I was never all that satisfied with the speakers though. They were a bit...

    Help request: MA6100 speaker switch and pre out questions

    I recently picked up a nice condition MA 6100 integrated amp that now works well with the following exceptions: 1. Front panel Speaker selector buttons seem to be bypassed as speakers work whether buttons are in our out. Status lights operate as they should - on/out, off/in. Even with the lights...

    Anyone ever modified PSB Image 2Bs? Worth it? What did you do?

    I'm looking at maybe purchasing a set of PSB Image 2Bs for a small system (20 WPC) I have at my cabin. From what I've read, they were decent speakers for the money. I don't intend to use a sub with them. I'm wondering if anyone here has tweaked/modified a set of these, what they did and what...

    Upgrading Vintage Marantz 1030 Power Supply to Zener Transistor

    Hi, First time poster. I've started cleaning up and recapping a Marantz 1030 as a summer project. It's going well. However, one of the things I'd like to do - due to its relative ease - is upgrade the power supply to a better level of regulation. To do this I'm going to replace the resistor to...

    Older Rega Planar 3 pulley upgrade?

    I recently purchased a metal pulley for my older model Planar 3 but noticed (before attempting to remove the plastic one!) that the metal one was decidedly larger in diameter. The pulley is from Analogue Seduction and listed as a Rega part, designed for the P3, but I am guessing that there is a...

    Beefed up speaker stands

    I have a pair of inexpensive speaker stands that needed a bigger base to set my speakers on, so I did my own mods on them. Used vinyl veneer coated mdf and attached cork board cushion on each shelf. Attached shelving to each stand with 4 stainless steel screws. Much better base for the...

    MCS Speaker Crossover rebuild

    I'm restoring a pair of JBL 4311b, and even with a few broken drivers my dad walks over and says, "these sound kinda like those MCS speakers we have upstairs". He's right. While the JBL's have much more coherency and clarity, the 12" woofer feels a lot like the MCS 683-8227 12" woofer. These...

    Anyone know how to disable the pitch fader on an 1200-mk2?

    I have a mk2 from 1979 that I've been fixing up that has a bit of a dodgy pitch fader. It doesn't solidly click when in the zero position and sometimes I have to wiggle it to get it to sit in the right spot. Since I'm not a DJ and only ever plan on listening to records at the proper speed I was...
