    SA-9100 Protection releasing too soon.

    I've been going through a very abused SA-9100. To cut a long story short, I looked through a number of threads dealing with them and rebuilt the power supply and all the other boards, powered on and everything is great except for this one problem. I read that the protection shouldn't disengage...

    B&W Matrix 803 series 1

    So today I got myself a pair of massive B&W floorstanders which look like they had a very, very rough life at the hands of people who did not care for good quality speakers which they are supposed to be. Unfortunately I was not informed about the missing tweeters which seem to be kind of...

    Howard's Restor-A-Finish Question

    I'm restoring a set of Large Advent's with the beveled edge that I bought new in 1973. The question: What color? Dark Walnut or Walnut? The cabinets are in very good shape but need a little TLC. I've never used the Restor-A-Finish (heard it is great stuff) before and I'm looking for advice...

    Marantz 1122DC Restoration

    Well I'm always a sucker for a new project. Next up on the list (at least worth posting about) is my first integrated, a Marantz 1122DC. It looks kinda pretty on the outside which is what attracted me in the first place. But boy the inside is sure a dirty, dusty mess. I think this thing was...

    Marantz 1060 : complete overhaul

    Hello again, This is my first 1060, bought off our local auction site, knowing it was defective. This time it wasn't an easy fix.... It turns out the amp board had been badly hacked in attempted repairs, the rest is fine and untouched. See this thread about how I built a whole new P700 amp board...

    Sansui 1000a restoration advice

    I got a fully functional sansui1000a a couple of years ago. It's in great shape, but has never been serviced. Every knob turn is scratchy and although it plays, I don't really want to even plug it in with all those old caps waiting to crap out (it being of the ancient tube sort of gear)...

    Leestereo's Restoration & Upgrade of a Rotel RA-970BX

    On the bench for restoration and upgrade is a Rotel RA-970BX integrated amplifier. Although consensus is relatively rare in the audio press, the RA-970BX has managed to garner praise in the Stereophile Recommended Components list, the HiFi World Buying Guide and What HiFi? magazine; it is also...

    New to Me Akai GX-220D

    Just bought an Akai GX-220D from an estate sale. It was filthy, and probably hadn't been played in 20+ years. Spent the afternoon tearing it down, cleaning and lubing it, then cleaning all of the pots/switches/buttons. Just hooked it up, and it sounds and looks like it just rolled off the...

    I finally found a 1060, since everybody raves so much about them, it will be here next week and I would like to recap this unit. I was wondering if there is a stock list (value for value as, or close as possible) for this unit. I have seen some threads on upgrades and modifications, but I...

    Is it the IC or something else?

    I've been working on an SX-V80 I picked up a month ago or so. Giving it a recap, replacing very worn trimmers and some resistors. I finished the job and powered it on for a test to find the left channel was very weak. After a lot of probing, I've found that the signal remains strong all the way...

    Sanded through veneer. Repair options?

    Hey everybody, I recently picked up this Telechron 602 clock and wanted to restore it. It wasn't running and I quickly found out that nobody had worked on the internals in many decades; perhaps never since it left the factory. The B2 rotor was locked up with tar-like grease, but I was able to...

Three output transistors are not original. The relay clicks after two seconds once powered on despite the DC...
