    Marantz 2230 Output Transistors overheating

    Hello, recently I finished a full recap of both the left and right p750 amp boards on my marantz 2230 as well as replaced the three small transistors on each board (not the snowflake heatsinked ones or output transistors.) This was about three days ago and I have used it a fair amount since with...

    First recap job with Sansui 8080

    Got a Sansui 8080 and already replaced all the fusible resistors on the driver board F2436. Trying to recap most of the electrolytics. Regarding the power supply filter caps... The existing ones (2 x 6800 uf) both measure good and are measuring above 7100 uf in-circuit. I would like to increase...

    2245 p800 problems

    Aloha AK, I was 96% done with a full recap of my 2245 with no problems. Phono board, preamp, and both power boards all done with no shorts on DBT, audio in both channels. I adjusted the idle current and DC offset on both boards just fine. I got to the main power p800 board, recapped it, good on...

    Another Sansui 4000 recap story...

    Well guys. Thought I'd share here my experience repairing and recapping a Sansui 4000 that was in dire need of attention. I bought this receiver several years ago (~$100) with the intention of rebuilding it. Actually, I bought two. One being specifically for parts. It came to me in fair...

    B&W dm4 speaker rattle, crackling noise at specific moments only?

    So I know next to nothing about speakers. I have a pair of dm4s that I haven't looked at for years. Today I tried them and noticed that one of the speakers sounds kinda rattly at certain points. I also feel like the volume drops at times but I cannot confirm this. I also find it very hard to...

    Thorens recap?

    There is a cap and a resistor in the thorens td165. How important is it to use mkt cap again in this circuit? I ordered a mkp and then saw somebody on eBay selling kits for the thorens and they used some mumbo jumbo about the importance of mkt in the circuit, which doesn't have to do with audio...

    Kenwood GE-1100 graphic equalizer repair (recap and analyzer issues)

    I've been using this beautiful unit for a little while now and thought everything was fine, although a bit crunchy when pressing buttons. The Sound has the 'warm' feeling from old caps and the power supply caps for sure need to be replaced, hence that thread. The first owner was my father, unit...

    Which To Keep And Refurbish

    Hey everyone, hope I am not breaking any rules with this first post, but I have just arrived, and I am still getting costumed (used to be more active around here, but the latest years draw my focus elsewhere!) to the AudioKarma way =) TLDR: I need help choosing which devices to keep and restore...

    DYNACO ST-120 Restore to former glory

    Dynaco stereo120a Restoration I have had this unit for many years. The last time it was in service was about 15 years ago. As far as I can remember, it was working well. I did not test the unit before I began working because I was worried about causing damage by powering up before some...

    How I Re-Stuffed Sansui Eight Main Caps

    Working on a restoration/re-cap of a Sansui Eight for a client. Since the main caps are such a large diameter, I wanted to re-stuff them with slightly larger and higher voltage caps (8200uF, 80V, 105C). At my regular place of work we have a small machine shop which includes a lathe. I chucked...

    I recapped the tuner on my HK 730 Twin - I was careful to ensure every cap was oriented correctly the right value. What's the best course of action to track down the issue?

    Merry Christmas AK'ers! I could use a little help solving a blown fuse problem on a SX-727. This unit was my first recap project, done 4 years ago. Following AK threads I bravely dug into a SX-727 to recap it, but little did I know how hard/easy it was! I figured even if it blew up it could...

    Help refurbishing Sherwood 7100A

    I was able to snag a cheap Sherwood 7100A after reading a ton of positive reviews about it on AK. It has a very weak left channel (seems to be common), so I decided to use that as my motivating factor to replace everything I can for my first project. Although, I've run into a few issues that I...

    ML-1C Dampening Material ?Question?

    I have a pair of ML-1C speakers acquired last year that I plan to recap the crossovers on. I have the caps and resistors and material to put the woofer back in with a proper air tight seal. When reading Roger Russell's page I saw that the speakers are an 'overdamped' design. I believe this has...

I'm really hoping to get it restored as I miss the man dearly and this keeps the memories going as some of his favorites play over it. I'm having a hard time finding a place that...
