PLEASE PLEASE NOTE! This is a listing for my stereo rebuild service only, not for sale of any
unit! See pictures of a typical rebuild below. A detailed photo CD is included with every rebuild to show work done! I have
now done over 250 rebuilds of Sansui, Pioneer, Marantz, and Kenwood
Receivers. I specialize in the Sansui 9090db, and the Pioneer SX-1250, along
with the rest of the Pioneer line. I have rebuilt most of the common Marantz
units, from the 2230, thru 2285, several of the 2300’s, all the 4400(Quads),
and even the 2385, 2500 and 2600! I also specialize in a very unique rebuild on the 9090. I rebuild and modernize the Power Amp, bringing back incredible sound, see last 4 pictures above. The db came in at least 3 configurations during its lifetime, I rebuild them all to the last configuration re the Power Supply. The Power Amp has 2 configurations. I don't change them, and replace all parts with the best.
These
are all over 45 years old now, obviously they need to be recapped, but consider
the 4 year old transistors! I fully rebuild all boards except the FM board. This is truly a rebuild, I replace capacitors, transistors, many diodes, many resistors. I fully rebuilt the Power Amp board with all new transistors, all new caps, and I replace all 14 of the fusible resistors. Those are what fail on this board. My rebuilds come with a Full One Year Service
Warranty! Photo CD with some video is included with the rebuild. I must do 4 or 5 units every year that have already been rebuilt, and I see incomplete jobs. That's why I get them.
I do around one rebuild a week, and I get to hear the before and after
sound on every rebuild! Most I rebuild arrive in “working” condition, even
these are revived, restoring their clarity and nuance! Check my 2360 Positive

You are buying what I consider a full service on Sansui 9090db and 9090, both pictured in this listing. This will be a partial rebuild and major recapping. It will including disassembly down to the chassis to gain access for cleaning and deoxing all tone controls, and inspection. A complete cleaning including faceplate and knobs. Includes recapping of all 3 power supplies, tone boards and Phono/EQ, and of course the power amp boards. I use all Nichicon Fine Gold and Muse Audio Caps, where possible, and Nichicon 105c caps where higher temps are an issue. All caps are preconditioned before installation. Does not include replacing the large filter caps, if needed. There are also troublesome diodes, and some fusible resistors on the PA boards that are routinely replaced. On the 9090db, I rebuild the Dolby board and repair all of the flow through connections. I have totally restored the Dolby function in over 90% of units. I don't replace any caps on the FM Board unless I see an issue. After rebuild, the DC offsets and Bias are set as close to factory spec as possible. Dead on arrival units may be more. On average between 60-70 caps and 20-30 transistors are replaced.
I guarantee my work for 1 year, not including additional parts, or shipping. I also will be happy to service your Sansui again in the future, if necessary, labor, parts, and shipping not included. Warranty includes labor, except in extreme cases. After I am done your system will be good for another 40 years! I sell many of my rebuilds on ebay where I have 2360positve feedbacks.
