Hey Carverites,

 

I have a TL-3200 that i simply love (more then my Emotiva ERC-4). The problem I am seeing now 9after getting the display lights replaced) is that when i play a CD, most of the discs will skip at some point on track 2 and then later in the disc (perhaps track 5, track 8, etc). I suspect it has something to do with the position of the pickup wrt the position on the CD (closest analog i can think of is how a tonearm/cartridge tracks on a vinyl recording). The tech I took it to said 'the laser pickup is shot. And i cant get heads anymore.' I would hate to think I cant play this jewel reliably any longer. I am the original owner and i want to keep it in the system.

Does anyone have any DIY fix suggestions or parts source?

Thank you kindly,

Joe

P.S. - located another thread that lists replacement lasers, so hopefully THEY are still available.

I've had 3 Carver CD players from the early years (TL3300, DTL-100, DTL-200 MkII) and I've seen a variety of issues.  One I was able to get working to about 95% reliability (still skipped every so often) and I gave that one to another member on this site.  One I chose to give up on...and scrapped.  The last one I have is the one I'm still using DTL 200 MkII.  It came relatively new in box a few years ago and works great.

 

I've learned a few things in playing with these units.  1. The belt drives go bad in some of them.  They are little rubber bands that like to deteriorate over time. Check for belt slippage.  You can get replacement belts on line for pretty cheap and it's not too bad to fix.  2. There are thin metal rails that the transport moves on perpendicular to the disk grooves.  Lubing these rails with a light silicone oil (real light so as not to get goop in any other parts) and cycling through a few complete disk travels can help.  Sometimes they get dry or slightly corroded and cause the laser to hang up or stick a little.  I've also noticed that the skipping can be more prevalent on a cold start up, which I think is related to this issue.  3.  The pickup lens can get dirty.  Clean the lens gently with alcohol and a lens cleaning paper.

 

Those are the "easy" things to do.... and they may help your situation.

 

If you are still skipping after all that, then you are likely into the transport mechanism and/or a new pickup .  I think that's much more difficult repair, so I've never attempted it.

 

Somewhere on this site is a list of which manufacturers made those Carver CD players.  Other than the DTL feature, the CD players were the same design built by other companies for Carver corp to badge as their own.  I think one is an AIWA design, I can't remember.  Do some searching here. You may be able to find components from the sister units built by the original manufacturers.

Thank you Kurt!

 

When I took the unit in to be serviced 3 mos ago (4 shaky fingers, 2 old eyes and one solder bridge later), the tech had lubed the sled and did his best to adjust/clean the lens. I cant recall if they did anything to the belts. I will take a flyer on a replacement lens (ChatGPT/Gemini/Google) all said the Sony KSS-152A is a direct/cross-matched replacement for the DLBA-1. I figure $32 is a small enough risk to take, cuz damn, I really LIKE the 3200! Funny, as I write this, I am into track 3 of "The Gershwin Connection" by Dave Grusin. Not a single hiccup/skip (I know.. I know... famous last words).

This may not be relevant to the mechanics specifically. I have been re-ripping my CDs to FLAC lately, and I have uncovered quite a few of them that just could not be read and fail. Ever hear of CD deterioration? Yes, it exists, see these discs. Consider your test media. However, you did mention specific track failure points.

YOWZER! That is indeed deterioration! I can honestly say I have not seen any of my CDs look like that. I will keep an eye out on the age of my CDs. I have some new ones (purchased in the last year or so) that I will give a play to on the Carver and see what happens. Thank you for the suggestion, Brian!

EDIT: Following up to this, I played two(2) CDs that I purchased last May and only been played a couple of times in the Emotiva. Both played completely from begin->end without a skip, bobble, hiccup. That is indeed another data point on this thread.

EDIT 2: Well, THAT was short-lived. I replayed the 2nd disc and found a couple of skips (which is a shame, cause I really like "The Milagro Beanfield War" by Dave Grusin). "New" pickup ordered. Should be here by Monday and off to High-Tech Audio in Stevenson, WA same day.

Alas,

 

I followed the reference to order a replacement for my DLBA1 on my TL-3200 and ordered a KSS-152A. The laser head arrived Tues, and I drove out to High-Tech Audio in Stevenson, WA. Roland took my Carver and the new head and set to work on it today. Sadly, I received a call from him this evening about 4 pm PDT. The laser pickup wont fit! The body of the new pickup is too big! It would get past the large cogged wheel (sadly, the images are too big to be loaded). The suggested replacement is a bit of a miss (KSS-152A). If some found a way to get this unit to work, I would love to know. Otherwise, I think the suggested table is erroneous.

I saw your pics in the diyaudio site. Definitely not a drop in replacement part. The laser diode is not even close to position. A quick search reveals that the DLBA1 part is in a NAD 5340 player, according to the links below. The second link is to that NAD 5340 for sale on eBay. I dont know what you paid for the new part, but you could take a chance on the NAD 5340 as a part source.

Thank you Brian!

I may just purchase the NAD (since a working unit is going to approx $90 from the cursory search I performed).  The one laser pickup I DID see is $156 located in Germany. I can get a working unit for that. 😆 The good news is since I purchased it on amazon, I can get my money back (all of $40 USD). 

I have some decisions to make.

 Joe,
Just know that NAD player listed in the link above is not verified by me. You may want to grab its service manual, look up the part. Let us know if you will go for the cannibalization direction 🙂

Looked at the Service Manual for the 5340. In the NAD manual it references a "Laser Pick-Up, TOPH-7830" (Toshiba). Cross-referencing further I learned the direct replacement is: KSS-152 (🙄).

At this point I wonder if by some (irritating) chance the part that was pulled is the wrong part. Granted, it isnt as if I were to order an engine for a 1962 Chevy small-block 6 cyl and I was delivered a 6.2L V8 for a GMC 1500. Wait a minute...

I am in for 2 hrs of tech time and I have no desire to try and try and try for a working laser pickup. I do have questions as to who determined the KSS-152 is a viable replacement. The parts were not even close to mating. Ok, rant off.

Its the price we pay to keep old mechanical devices working. If I were trying to fix the deck to add to my Carver Stack, at least for working, AND MATCHING component, I would risk the 5340, ONCE!

Best of luck. Dont allow this is to irritate. Some of the best car restorations have to wait it out to find the right part, searching every corner of the world 🙂
