    Hi, recently the left channel of my Dared SL -2000A became noisy, it sounds like deep frying. My tech friend can't seem to isolate the problem. I would appreciate it much if someone could tell me where to find spare boards or maybe used units for sale. Thanks very much.

    Auction sites.
    Try new tubes?

    Hi, tried new tubes, still noisy. Nothing on ebay. Will call Mike of Deltronics for a spare board. Thanks for the comment.

    Hi,
    Need assistance, if anyone comes across a used Dared SL-2000a or a circuit board for sale please let me know, I will appreciate it much. Thanks.

    I’m going to pull this from the grave…

    Does anyone have the schematic for the SL2000A?

    I can’t find one online.

    I emailed Dared, no response.

    I also tried to get in touch with Deltronics, in Chicago as they were an authorized repair center for Dared in the past.

    No response to email and no one seems to answer the phone.

    My SL2000A developed a hiss and static in the left channel.

    Thanks in advance!

    Yeah, I was worried that was going to be the answer.

    I'd run into a problem with uploading the file, but it now looks like it has posted properly. If not, let me know and I can try sending it to you another way.

    Quick update, couldn't really figure it out on my own and I ended up hearing back from Deltronics.

    Ended up sending it into them, they called about a week later that they found some poor capacitors.

    Gave the okay to repair and I hope to get it back within a few weeks.

    Follow up, received back from Deltronics.

    Absolutely not a quick process…

    They had it for 3 full months.

    Either way, it’s home and back up and running.

    They did a full re-cap on it and it’s sounding better than ever!

    I’ll run this for now, till I find my “forever” preamp!

    I have always liked the look of that preamp.

    For what's its worth, 3 months for service work is beyond normal. 3 to 6 months is normal for any type of service work in 2025

    Posting some hopefully higher res pics under the hood for you reference.

    This is the Audience cap version. Would still love to find out what type of remote this uses for the remote volume control, I believe it uses RF (Radio Frequency) signal for the remote control volume? You can see a red wire coiled up, marked ANT. on the board.

    Anybody here, can you look inside your remote and see if there is a FCC ID code inside the remote in the battery compartment and post it? That would help a massive amount. Thnx

    PS: Its sounds nice and quiet with vintage USA tubes & 5Y3G Rect.

    This is one of the last ones made I believe. I think 2012. SMD resistors mostly. Different amount of Electro's & Poly caps.

    Mines a mess & quite dusty. Took it apart a couple months ago to get all the values (never had a schematic)..so I ordered & received all the caps about a month ago & just haven't found the time. They've all been desoldered & are hanging by a string. I have some V-cap Odams from another project I'll put on the input.

    It's still a great preamp. I had the earlier model but this one didn't give me the gain issues the older Dared gave me. I've had a few tube preamps, the one I'm currently using probably close to $3k with upgrades & the sound of the little Dared is just kinda special to me. I feel like you can't find this type of sound or presentation in modern gear.

    My favorite tubes were the Tungsram 5z4g & the German made Amperex e81cc PQ gold pins. I preferred the bass of the Tungsram over the soundstage of the Brimar rectifier. Rectifier really affects the presentation on this preamp.

    Thank You HalfOhm for the reply, all the info and wonderful pic of the inside of remote; its very useful. And looking forward to seeing pics when you've finished servicing your 2000a

    I've been going down the rabbit hole about RF remotes and programming; it's a deep hole (and not my forte). The Dared has the PT2272-M4 Integrated Circuit chip in the amp, and a HS2262A-R4 in your remote. If this is the case, then the key fob freq could maybe be 433MHz, or a 315MHz; but there's more to it than just the frequency, theirs data streams, output flows.....etc.

    They're super cheap enough on the _Bay to try both. I'll report back, if one of them works.

    There are pictures on the net from days past where folks used a key fob to fix their original Dared remote. It fit right in the factory hold IIRC.

    Thanks pitdogg2. I'll try a key fob, and if the preamp sounds as good as described with some of the recommended NOS tube & rectifier (I think I may have some stashed away). I may make a remote control case with my mill with key fob board inside.
