So bought a HK 930 and have been using it for several months. Given the superb shape of the thing, I wanted to make sure it would sing for another 40+ years and wanted to dip my toes in receiver restoration. I work in turntable currently but receivers are a lot more electrically technically...

Picked up this console today with a very serviceable hk ta-224 and some really cool Jensen 12” duax Alnico speakers. Does anyone know if this has built in multiplex? I can’t find a definitive answer online. The receiver is chock full of telefunken 12ax7 tubes! And before you get mad at me for...

I have a HK330i. Had it for years. Use in my garage "cave"... it's been great, except for one quirk... when adjusting the balance the sound will cut in and out and sometimes becomes muffled. I have to very delicately adjust it to get the full stereo sound back. Any idea what is causing this and...

Hello: This is a total newbie question… I am just now trying to get into collecting vintage audio gear, including receivers. There is a Harmon receiver (TA 260) on sale nearby. However, it doesn’t have a cover (cabinet). Would it be smart to purchase this with no wood cover? Are covers...

So I've got myself into a bit of a jam and hoping someone here may be able to help me out. My citation ii recently had a bit of a meltdown while I was attempting to set the bias on my tubes while switch from triode back to ultra linear. The first 2 tubes biased no problem but when I switch to...

Hi everyone, i am new here. I am looking to buy a secondary receiver to always have an option and i found these two models. HK385i vs Technics SA R277 ..Any idea why HK is the best option ? its a 45$ difference in price. Is it that worthy ? I keep hearing sooo many good things about these. and...

Hi all- I'm a newbie here, just started collecting vintage gear. Picked up an HK 430 yesterday, and ran into a not small problem that it will not power up at all. No lights, nothing. I opened it up and didn't see any blown fuses or other obvious signs of failure. Anyone have any ideas about...

Hey there I have a HK230e I'm trying to clean up. How to I remover the plexi wraparound cover? Cant find much about this one.

Somebody on my local Craigslist is selling a nice looking little receiver with the brand name Sound, model R-700. Made by Nippon Sound Company. Wood case. Really pretty. Elements of it seem like similar vintage HK or Rotel. Anybody know who sold this brand at the time? Some store brand...

Hey team, I’m moving! unfortunately I’m going to be scaling down my current tube system running on my Tannoys, I’m moving out of Missouri to the east coast in a few months and will be living in a smaller living space. I’m absolutely committed to keeping my tannoy 12 golds speakers….but I now...

This HK AVR 1700 was a curbside find last year. Initially when I took it home and tested it out I was amazed to find a working HK receiver that was new enough to have HDMI ports. The receiver worked fine and I put it into service. Then I learned why it got thrown away. It works perfectly...

Hi...I have a Harmon Kardon Signature Series 2.1amplifier, and the inputs appear to be single RCA jacks. This is probably a stupid question, but if it's a single RCA, how do you hook up a stereo input? Is there a special RCA cable that takes both left and right and channels them via a Y...

When I power the unit the am and fm has no sound initially. A couple minutes later the sounds starts to increase. Then after a couple power on/off's the sound is fine. All other functions/switches/inputs work fine. It is 70 degrees here now. The problem was worse during the winter. The...

I have a 730 with a problem. One of the channels keeps blowing a fuse. Sometimes a new one will last a second, sometimes a week. I've taken it to a couple shops, and they will think they fixed it. They will test and everything, but within a week, it always blows the fuse again. Any ideas what...

I have a Phillips sub that’s decent , I’ll show it and model # it’s definitely better then speakers that are with it . Get pics soon But the speakers that with it are a weak link. Anyway to attach my Hk pc speakers I found at goodwill for $4.

First of all, Hello! Recently joined this forum and this is my first post. I recently picked up a pair of Polk Monitor 7s and was looking to find a receiver that would go well with those. My listening space is medium sized with carpets, a popcorn ceiling and some couches. As luck would have it...

Hey everyone, lately I've been having issues with one speaker overheating and I'm worried it might be an issue with my receiver. I have a budget set up of a Fluance turn table which is connected to a Harmon Kardon 590i and c100 Energy speakers. The issue started yesterday when my left speaker...

I rescued a Harmon Kardon Citation Eleven pre-amp and Citation Twelve amp from a basement in Massachusetts. After a thorough surface cleaning, a few blasts of canned air and some De-Oxit attention, I have a functional, and quite loud, system up-and-running. I have my Technics SL-1100A running...

I picked up an HK 330B that I LOVE. I'm running my KHL Model sixes thru it and it sounds great. After some different reading on the net here and their, I got worried thinking maybe that I'm underpowering the speakers and causing damage... Anybody's thoughts on this? Is a Harmon Kardon 330...

Does anybody know what size the retaining clip and washer are for holding the platter in place on a ST-8. I just recently acquired one and it came without these two pieces. The table runs fine without them but it would be nice to have things as they were meant to be. Also, any suggestions on...

Hi guys, Have been enjoying the site, the helpful members, and the massive amount of info available. I'm going to dip my toes in the tube world for the first time however my pockets arent very deep at the moment. My repair guy has a Harmon Kardon Trio tube amp that he is selling for 150.00. I...

Ok so I got the amp given to me. And it needs repairs. Its missing a power amp transistor. Needs two resistors and this other part not sure what it it tho. I'm having a hard time finding replacements. The little silver one I'm not sure what it is. Any help sourcing parts? Thanks in advance...

I have the entire HK Slimline system at a shop for repair, he's recapped the tuner/amp, new belts for the tape deck, belts for the BSR sourced turntable. But we've hit a roadblock and hoping the AK gurus can help. He's tested and determined the ceramic cartridge itself is bad outputting one...

I recently purchased a Harmon Kardon 730 receiver. It arrived damaged and the seller told me that there's "Nothing he can do about it". I want to try to fix the tuner myself and am hoping that someone can provide helpful information. Here's the problem: All inputs work fine, except the...

I just finished a complete recap on this HK 930, 1972. I have done dozens of rebuilds on newer and bigger receivers. I also did and HK 730 in the past. My client wanted this rebuilt, even though it sounded pretty good to me, and I advised against it at this time. But jobs are hard to come by, so...
