Hey guys, so I recently acquired a 300DC off of that auction site. Seller didn't disclose the fact that it had been worked on at some point. Looks like it got a full recap, but some of the work seems a bit shoddy and the cap selection almost seems random. Figured I'd ask here about what you guys...
Hopefully this thread will provide some future person a point of reference the way that I have used other threads on this site for my own reference.
I'm going to put my questions in bold as I come across them. Hopefully there are a few people who can help me out. I recently picked up a...
Hi all! I have been restoring a set of Tannoy Lynx speakers from the Wildcat line from the mid/late '80s. It actually took me a while to figure out what I had as there are no model names on the cabinets and no part numbers on the drivers. Google image search helped a lot. The drivers are the K...
At the request of AK member @greymatter, a very nice Sansui CA-3000 was the subject of a complete restoration and upgrade.
Part 1: F-2486 Equalizer (Phono) Circuit Board
In the CA-3000, the phono stage consists of a pair of F-2486 boards, one for each channel.

Hello AK'ers,
I've really enjoyed reading up on incredible amount of information here at AK. Thanks to everyone for posting.
I recently obtained a set of rough JBL 4333a speakers and am about to restore them. Following some advice here I just installed new surrounds on the woofers and the...
So I said I would make a thread for this, just getting around to look at it. Never seen one with quite this issue, amp board looks like it got very very toasty.
There's melted plastic on the top above the amp board:
And the plastic caps on both main filters are rounded from heat, and there's...
Good evening everyone,
Having the chance to sit down after finishing tonight's project (which took nearly 7 hours), I was compelled that my experiences were worth writing about. Just before Christmas I found a pair of Pioneer CS 99A speakers on craigslist by some miracle for only $100 and...
Hi, all!
My wife gifted me a couple of vinyl records for Christmas along with an entry-level turntable. The turntable sounded absolutely terrible (we got what we paid for) so we sent it straight back, but I did like the idea of getting into vinyl so I've been on the lookout for a better...
Had tons of fun restoring an SX-780 and two 636s (one for my son and another for my daughter, who’s starting to spin vinyl). My friends and family had either forgotten or never knew, just how good music can sound. I was able to pick up an SX 737 from a local Salvation Army store. FYI they are...
Hello everyone,
First post here. I have been reading some posts here & elsewhere about who to send my good condition A-1000 to have it serviced & restored.
I had a local "service shop" work on it, they said they replaced some outputs, but when they stress tested the unit, they immediately blew...
Hello everyone,
First post here. I have been reading some posts here & elsewhere about who to send my average condition SX-1250 to to have it fully restored.
These are the guys I have found. I'm looking to find out who you recommend & why. I did talk to the guy at Many Moons. I put in...
Hey guys, so I recently picked up a set of technics SB-6000A off of a guy for $100. He also had a Marantz 2285B listed for $50 but by the time I contacted him, that was long gone.
They're not in too terrible shape:
Im planning on cleaning up the cabinets and drivers and getting that dust cap...
First, here is the finished product:
Here is the unit the day I bought it. I got it off a guy from Facebook Marketplace for $100. It turned on but wouldn't play any sound. It was a bit grimey and had a few dents in it but it was in good condition otherwise.
Lots of grime...
A few...
One of our outstanding local AK'ers, @nj pheonix , asked me to recap and restore his monster-of-a-receiver Heathkit AR-1515.
It is quite a beast, lots of power, an unusual design (on the inside), has the rare Dolby FM card, and was a lot of fun (read as "learning experience") to work on. This...
I could use some help from AK members. I own a couple of Concept 11.0 receivers and need to know what service and restoration choices are out there.
I am aware of a business that services Concept, but I was told they have a waiting list greater than four years!
A lot can happen in that time...
Hi,
I just received an old mixer from the eighties that has been stored away in a basement for more than 20 years.
It was stored in a flight case and all the pots and faders are "glued" and wont move at all. Of corse I dont use much strength to try to move them since that would totally damage...
Hello everyone!
I would like to restore my dad’s 1979 Accuphase P260. The amplifier has had a rather hard life. As of today, it is not fully functional.
The amplifier’s history:
It was bought in the 80’s as fully functional.
In the 90s, the amplifier got water damaged; it was repaired: the...
Mine are original owner speakers, stored in ideal condition for several years. Pots are in need of replacement or repair. Speaker serial numbers are FX-250128 and FX-246425. Strange, because they were purchased at the same time, of course.
So questions. The cloth surrounds look OK but the...
Hi, I came across these, heavy, looked cool. Did some research on Nestorovic. Not experienced with working on speakers. I live in Los Angeles and wondering if it's worth having these restored. Cabinets have a few small knicks, need some patching also. I have the grill, fabric needs replacing...
Hello everyone!
I just picked up a Grundig KS400 console. AM/FM works but the turntable doesnt turn. I can't find anyone near me (Massachusetts) who will even look at it. Is it really junk at this point? I was so excited thinking it could be restored but now its looking unlikely. Any...
Hey guys, so figured I'd document my fun that I'm going to have with my recent acquisition of a "for parts" 2270 from ye olde evil bay site. According to the seller he started recapping it, then ran out of time to finish it, although my bet is that he messed up somewhere and gave up. Apparently...

Figured I'd start posting the restorations/rebuilds that I am proud of here. I dont keep much of the equipment I get as I am happy with what I have and dont need a room full of marantz (though I'd like one).
This 3600 came off of ebay, along with a 250M with a destroyed channel for $700 or so...
Complete noob here so excuse my ignorance if this is obvious to others.
I had initially posted this here the "Exclusively Sansui" section, but perhaps this forum is a better fit.
I've replaced the faulty transisters in my 2000a and it got rid of the popcorn static. It still has a slight hum or...
