Taramps MD8k Remote Circuit No Start Magic Smoke IC Repair

[@jakeclark3298]

Thx for your knowledge and vids. Learning amp repair is a pass down trade and guy like you and barevids are rare. People complaining about 75$ is the same reason us techs complain about Oscope, rework station, solder iron tip and test equipment prices I think it's fair and would pay.

[@ellensburgamplifier]

So true! Thank you for the channel support.

[@jordanciaramitaro6351]

I have repaired a few of these as well. My theory is the failure is related to shorting between the speaker output leads and the remote lead. What I haven't determined if it's internal arcing or external loose/strands. The latter is my strong suspicion though.

[@warthhoh]

Fantastic video

[@ellensburgamplifier]

Thank you for watching. These darn ICs, one day I will have a workaround to this problem for amps out of warranty.

[@awaazhoosein6565]

Nice work

[@ellensburgamplifier]

Thank you! I have a wide audience so maybe these videos will help others fix their amp. Thank you for the support!

@@THEBEST-vg5wt Thank you. Your box is marked for a video so I will do my best to record one or go live with it. There are 7 amplifiers ahead so soon I will have it on the bench.

[@THEBEST-vg5wt]

@@ellensburgamplifier thanks so much I would send you another from taramps thanks

[@ibntheibn]

I crossed the speaker wire with the remote wire when running no smoke no smell just won't power up please help same thing i think

[@michaelwaterman4827]

Reason I had was that ,my live remote wire touched the negitive speaker wire connection port and caused it to short out

[@ellensburgamplifier]

Yes, that will send rail voltage to the IC that the remote turns on. At that point, you will need a TPS7A6601, 4.7 ohm SMD resistor, and a 4148 SMD diode.

[@djbell9939]

what is ic 1 beside it and what it does

[@ellensburgamplifier]

IC1 is the 22v aux. power supply for the 5v regulator. UCC27524

[@basshead100]

anyone can advise SMD Capacitor C71 details?

[@ellensburgamplifier]

100nF 100v

[@basscaddy1449]

What would you charge to fix rca on a taramps md5k there loose rn I have something under the rca wire put upwards pressure on them to keep it from making awful noises lol same thing I used to do to phone charger that were going out!!

[@ellensburgamplifier]

RCA replacements usually fall within my minimum charge for most amplifiers. www.ellensburgamplifier.com/request-a-quote

[@erikhubbert942]

Where can I just buy the whole board? Or do repair amps I have to 8k one taras and one bravo

[@ellensburgamplifier]

You can contact Taramps and if they have enough stock they may sell you a board. If it's a remote circuit failure (IC9- TPS7A6601) then that is repairable.

[@wizorm]

I have the exact same amplifier and the exact same scenerio happened to mines . Whats an estimated cost of this repair ?

[@ellensburgamplifier]

At the time of this comment, the cost for this job is $75 www.ellensburgamplifier.com/request-a-quote if interested in sending it in.

[@isthathimforreal6961]

Hi can you please give me those part numbers for the ic

[@ellensburgamplifier]

It is the TPS7A6601 IC

[@jasdeepsingh2501]

Is there a place where I can purchase the repair parts ? Or liek the part numbers ? Got a bass 8k that has voltage to the remote wire but doesn’t turn on

[@ellensburgamplifier]

I see Mouser has the TPS7A6601 in stock and I would bet Digikey has them also if you are here in the States. You may also need to change the 4R7 supply resistor and L4148 diode. This is if NO LEDs come on or try to come on.

[@jasdeepsingh2501]

Yeah I got no leds or anything

[@ellensburgamplifier]

@@jasdeepsingh2501 Yup, typical remote circuit failure. I have noticed that these repairs have tapered off substantially compared to last year so hopefully, this issue is getting weeded out.

[@jasdeepsingh2501]

I appreciate the help thank you

[@cartycartyamplifiersalesrepair]

That little ic is a big problem in alot of the Taramps I need alot of them right now $35 wow

[@ellensburgamplifier]

Yes, $35 so far is the lowest quote I received. I too need a bunch of these. I am also looking into the TPS7A6650 that may work but I see those are just as expensive.

[@electronicengineer]

I have left comments on this channel in the past and they were not all "sunshine & roses", however please believe me when I say that I don't try to come off as a negative Nancy through all of my comments, honestly, I just call it as I see it and in that vein, here I go again; $35.00 USD for an (one piece) LDO regulator is absolute INSANITY. I hope that you and Todd can locate a more reasonably priced supplier for this particular component. As Todd alluded to in this video, clearly these regulators are being priced at ransom prices. It is just nuts to hear that this is taking place... I'm sorry guys. Good luck with finding a down-to-earth priced source for these voltage regulators. Fred

[@ellensburgamplifier]

@@electronicengineer Thank you Fred. I will never pay these prices unless I am forced to keep business rolling smooth. It is unfortunate that I have to pass this price gouging onto the customers when I have to pay such outrageous prices for something that just cost a few dollars in 2020.

I bought that ic from taramps, 3usd for 2 pcs plus 30usd international shipping, yet mine doesnt turn on anymore

[@ellensburgamplifier]

Do you have 5v out on R154? Did you replace R99 and D21? If you have all the voltages present then we need to look further down the circuit.

[@cheri758]

@@ellensburgamplifier hey, it is actually my fault, funny thing is that after flipping it arround and openingnit turned on and cycled by turning off and on, after pressing on the ic with my finger it turns on and runs, well there's my shat soldering for you

[@ellensburgamplifier]

@@cheri758 These MSOP ICs are small for sure. Good solder and flux make for a quick job.

[@brick2077]

So on my md8k it puts out very low sound but if I touch the rca inputs it gets really loud what's going on here and is it an easy fix.

[@ellensburgamplifier]

That is interesting. Almost like it is missing the reference ground. What are you using for your input signal? Most anything is easy to fix on these boards as long as the PIC is alive and well.

[@ellensburgamplifier]

@@brick2077 The RCA ground, or the shield needs to be grounded or the amplifier will see a floating input which will confuse the feedback circuit in the amplifier. With the RCAs disconnected from the amplifier do you read zero ohms from the RCA outer shield to the chassis ground?

Amen to that! Thank you for the channel support.

[@electronicengineer]

I couldn't agree more with you. Also, at least from what I have seen of Todd's work now for the last half year, you will not find a more thorough, methodical, and caring repair technician than this man, Todd, at Ellensburg Amplifier Repair. It is relatively easy to see that he really cares about every unit which runs through his repair shop. Todd takes pride in his work. Fred

[@FrankStPeter]

Where's the salt 8K where's the crossfire C7 tired of seeing Brazilian circuits,,, I'm joking

I have a completely cooked Salt12 in! Also a Crossfire 8k on the way. Soon-up is a Soundstream X3.14k just waiting for the owner to pay for the last repair I did before proceeding on this one.

[@FrankStPeter]

Yeah those amps you were talking about in the other video I want to see a challenge for you,,, I was cooking earlier while listening to the video and you were talking about your pricing on repairs not trying to cut my own throat here but PPI and Orion had a flat bench rate of 125 and then would call you if more money was needed and that was in the 1990s so don't let anybody fool you you're cheap

[@daveydave9884]

People are cheap. Your repair is inexpensive in my opinion

[@ellensburgamplifier]

Agreed. Finding the balance between customer expectations and repair costs is a fine balance to maintain a good business model.

[@emilyhouse9642]

im curious how any of your repairs fail. IDK why you're putting an iron on that chip. 🤦

It's all in the finesse.
