That new-old Farnell TOPS 3D looks familiar, I remember using one of these at my first job in the mid-'80s, it's good to see an old beast like that still happily chugging along 😁

Hi sam brilliant video, i use this method to power up professional power amplifiers before i connect the mains after repair and during troubleshooting, much safer and with current limiting it really helps not make things any worse when some sneaky components are still bad !! 👍🏻

I have one small class AB modified running from a swtiching power supply from a small hifi system, the power supply is 220 AC to 35-0-35 DC, i took off the rectifier diodes, change some caps, modify some current sensing, and the thing works very well in my house, i use a pioneer subwoofer with it, permanently set up in my house. Greetings from Argentina.

Great video very educational keep up the good work Sam nuff respect 👍 👍 🙏 🙏 🇯🇲 🇺🇸

Like always, you're the man! Have you ever had one of these Korean amps pass oudio with a screeching sound? Can't seem to get rid of it no matter what I do. Looked at op amps and caps, all votages to card are spot on...

I was so confused watching this vid until I realized it said run instead of ruin.

Hi I have a orion cobalt 1200.4,changed all the transistors,MOSFETs and tl494 but no power ,can you help?

Hi there, I have a DLS a5 car amplifier on my bench, it's a 3 channel amplifier. The problem is the sub channel doesn't work, therefore when turn the gain up of the sub channel the amp goes protect mode. Mosfets seem ok but rail voltages are +28. -19.5 +32. -23 Any ideas?

Farnell psu? Looks like the one I have

Found my good tweezers. D~id you find yours yet? lol

on this video, what dc power supply you used?

You do this with virtually any electronic device while diagnosing/debugging ;)

buen video amigo barevids por favor me podrias indicar cual es el reemplazo del ic smd 77a524a taramps md8000.1 plis

Mejor que mires en foros en brasil... asi te puedes informar mejor sobre estos detalles, el mejor metodo es buscar igual es pajinas web mouser or Rs components, los dos son pajinas de web de inglaterra. si necesitas que te envie communica conmigo saludos amigo

Alright bet

Sam. How much would you charge to mail me the mosfets and transistors to replace ALL of them on a audiopipe 1800.1? New or used, don't care as long as working well! I live in Tallahassee, FL USA. Plesee humor me, and lemme know what you'd charge, bottom line.

Just buy them from mouser dude, why you wanna pay a fortune for the same parts from the UK 😂

@@barevids I'll check it out. Because I heard you mention you had tons of them. Amazon I felt was a rip off. Plus you have the general know how as go which mosfets and transistors will be equal to or acceptable without compromising performance, and I don't 😎. I've heard you mention there's other mosfets and such that someone could use interchangeably like I just mentioned.
