View Full Version : 9900Z FM pre-sets lost on restart

Hello,

I just joined the list today, but have enjoyed reading it quietly for a few weeks. Your knowledge helps 'hidden' people out more than you can imagine!

Anyway, I have a Sansui 9900Z (and a 9090 with a 9090DB en route as I write, all recent buys off Ebay.

The 9900Z got bounced around a lot in the tender care of USPS, and needed some immediate attention, but now works very well, apart from one minor but irritating flaw...I get a strong FM signal using a Terk FM Pro antenna (I live in the boondocks here in Indiana), and store 6 strong stations into the pre-sets. If I switch the receiver off for a short time (e.g. 5 minutes), no problem - the presets are all still there. If I leave the receiver off much longer, the pre-sets are lost and pre-set number 6 resets to the lowest FM frequency of 87.5 The other pre-sets still show on the digital display the frequencies that I tuned each to. Now, re-tuning is pretty easy on the 9900Z, but I'd like to have it all working perfectly. You can appreciate that, for sure! Any advice will be gratefully received.

My equipment is quite eclectic:
First System:
Sansui 9900Z;
Speakers Gale 3020's (handle up to 100w but not much low end - used with 9900Z - in the market for a decent pair of high capacity speakers!!);
Garrard SL95B turntable;
DUAL 1218 turntable;
Nakamichi Cassette 2;
Marantz CD65DX

Second System:
Sansui 9090 (used as preamp due to blowing F03 and F04 fuses - have read excellent advice from Echowars on Vintage Solid State and will be following this advice);
Meridian M2 active loudspeakers (using 9090 as pre-amp - wonerful combination);
Linn LP12 Turntable/Linn Axis/Linn k9


Also have DUAL 1009, Arcam Alpha 9C pre-amp, a Sony MiniDisc player and another Marantz CD player, but these are never used at present and will probably be 'released' from contract shortly!

I used to work for B&W Loudspeakers in 1982-3, hence the Nakamichi, which I recently repaired with a new capstan motor and converted from 220V to 110V (easy to do on that model) following my permanent move to the US from the UK. However, I worked in the accounts department, not as a tech, so not much help for anyone there!

The 9090DB I just bought on Ebay is a fixer-upper. I just love those Sansui amps, which I lusted after as a teenager (in the 70's) but had no hope of owning! These 70's units are just plain ADDICTIVE! My wife does not share my enthusiasm, sadly...sigh. She dreads the next straining delivery man staggering up to our door under the weight of another 55lb receiver!

BTW: Does anyone know where I can get hold of a 9900Z owner's manual and service manual?

Happy Holidays everyone.

I should say that, whilst the 5 other 9900Z presets DISPLAY the tuned frequencies, the receiver is not actually TUNED to them - it is just off enough to present hiss/white noise, rather than the wonderful programming we get here in rural Indiana!

OscarEmmy,
Welcome to AK. It's good to get another lurker into the "official" fold. Many of us know the UPS/FedEx guys by their first names.

Don't know much about the 9900Z but it sounds like what ever power supply keeps the memory hot is not there. It may be a capacitor or battery backup. You can get the service manual on CD in PDF format from these (http://gallery.bcentral.com/GID4884061DD322074-Sansui/Literatures/Manuals/Receivers/Z-Series-like-9900Z-or-Z-9000.aspx) fine folks.

Did you replaace the 2 AA batteries that provide the preset memory with power? Look for a small door on the rear of the unit. Not particularly obvious.

Thanks for the welcome and advice, Pete and John. Will investigate the battery connections - I did renew the batteries on the unit (you're right John, not immediately noticeable), but there is likely a problem in that backup power line. Thanks for the link to the manual page Pete.

I am also looking into restoring the anodized aluminum faceplate, top edge is gouged a little. I have read that this can be repaired by re-machining the edge and 'brush anodizing' (a specialist job) the stripped area of ali. I will post a thread to see if anyone has attempted this before. If it looks to risky for the rest of the faceplate, I'll pass on this option. However, I also intend to build a new veneered case (edge damage during transit). I saw someone on Ebay selling Marantz cases (I think) for $100 each yesterday. I'd just as soon do that myself. I will keep the old case in storage (authenticity, etc). That way, the unit will look 'new' again. This restoration project will take some time. I'll post images later. Thanks again.

To Pete and John - Just to say that I cleaned the oxidized battery contacts on the 9900Z and gave them a coating of ProGold and now the pre-sets hold perfectly. Thanks for your advice!

O-Em:
Glad things worked out. I'm having a similar problem on one of my other Z's, a 3900Z (my very first Sansui purchased new in ca. 1981/2). I haven't really gotten serious about it yet. There is a lot of corrosion in the battery compartment on this one, as I let it sit too long and the batteries leaked. I hope you'll post your listening results for the 9900Z. My personal opinion is that the xx00Z series is a much better listen than one would assume based on the typical eBay prices (based only on my experience with the 3900Z and 5900Z, which I hope to expand with a 9900Z due next week...).

Hi John,

I agree that the sound of the 9900Z is not reflected in current prices. Out of interest (nothing more - not going to bid!) I am watching a new Ebay listing of a 9900Z. The 9900Z's provision of two phono inputs is a great advantage to someone who wants to use two phono turntable setups (as I do, listening to 33.3 and 78 rpm discs). A disadvantage is that it does not seem sraightforward to use the 9900Z as a pre-amp only, so I am using the 9090 as a pre-amp (at which job it is excellent, by the way) for my Meridian active loudpeakers, which sound better than the Gale 3020's (especially bass response and 'warmth') until such time as I can get the pre-power amp drivers sorted on the 9090, (following advice for another AK member from the very knowledgeable EchoWars - I noted the G9000DB that he had sorted failed to attract any bids, largely due to a combinagtion of lousy Holiday Timing for the listing and an overly challenging $500 starting bid). I would love a pair of Sansui speakers capable of handling 160-200 watts, but am under a strict wife-imposed embargo on further purchases until I sell some items on Ebay (mainly DUAL turntables, plus my ARCAM Alpha 9C pre-amp and a Gibson Les Paul Studio guitar).

The 9900Z has a start of $99 and can be viewed here:

I paid not much more than that start price for mine and I find it an excellent powerful receiver with amazing sensitivity - it pulls in 5/5 signals all over the dial using my TERK FM Pro antenna (I would get another one of these antennae...but for the embargo :( ).

I have read of volume motor issues for this receiver, but the motor connections and type look very straightforward, so I cannot see a replacement of a defunct motor being any big deal - I could be wrong, of course! I think overall I prefer the simplicity of a simple volume control pot with rotary dial, but I can see that some would admire the very 80's styling of square up/down buttons. I know you will enjoy the 9900Z when it arrives. Mine works perfectly and was an absolute steal. The one on Ebay looks in even better physical shape and deserves snapping up by someone who loves Sansui stuff, so it will be well cared for.

I note you also require 'wife's permission to buy more' - ah, there must be many of us straining at leashes as we write! LOL All the best!

It's funny, guys, but it ain't funny. I have labored under these restraints for years, ever since I lost my field service job. (I had my own cash-flow and checking account) Now, I simply squirrel away some of my lunch money until I have enough to make a new acquisition, and have it shipped, sometimes, to my son's house. It gets tricky. I even built my two current PC's this way. Wive's just can't understand our love for gadgets. And not just any gadget, only the best. Here's a clue: buy her something nice. She deserves it.

Ya'lls talk of this series of Sansui receivers has prompted me to get out my 5900Z and give it some more consideration for use. Thanks guys.

Hi O-Em:
I saw the current 9900Z listing, too. If one puts these into a category even remotely related to the big G's (which I think are the immediate predecessors? G8700, G9700?), then the $99 start price is still massively low. I'd love to be able to do an A-B comparison but would want them in equal condition (so recapped and aligned, etc.) and that takes a big investment. I must say that looks alone would have me pay more for a big G, though the xx00Z's are tolerable compared to some of the even later Sansui's with gaudy (useless?) lighting. I think the push button volume and tuning on some of these models is undesireable and likely to fail. That is one reason I want a 9900Z, as I think it has knobs for both, and I'm nothing if not a fan of knobs! :D

I pulled the 5900Z out. It always had a power button issue. I took it apart and addressed the issue and have been listening to it all afternoon. Certainly not the best looking Sansui, it does sound pretty good and the tuner works very well. A nice match for my BA A70's. It looks like the 9900Z has a knob for tuning but not the volume. I doubt it will get much rotation into use but it did give me something to do for the afternoon.

Yer right Bob! But for woman who already has several Sansui receivers about the place, what more can she possibly need???? I ask you! I relate to your off-site deliveries...mine have always been 'ordered ages before the embargo, but took a long time to arrive' - how long that string will stretch is anybody's guess. If she ever reads these posts, I'm in BIG TROUBLE! Now to make matters worse, I just broke the stylus off my Linn K9 and note to my dismay that these are fieldishly hard to get hold of...looks like its back to Ebay for a cartridge upgrade (at least the small packages look less obtrusive arriving compared with 9900Z's and 9090DB's Haha

I too have a beautiful 9900Z, It sounds great and rattles the walls driving a pair of Sansui SP-X9900 speakers and a pair of Infinity SM-122 studio monitors. These 2 sets of speakers sound completely different but really complement each other really well. The low and highs of the Infinitys are the bomb, but the mid-range of the Sansuis really fills in and gives awesome depth to the sound. Altho I will be watching what the 9900Z brings on Ebay as i just purchased a McIntosh MAC-4100 receiver, and if the 9900Z will bring close to what it is worth mine may follow on Ebay as well. Its good to hear people talking about the 9900Z as you really never hear much about that series, and a good series it was. Dave
