Introduction
Hi I have used the forum on many occasions and I guess now may be a good time to introduce myself. I have been in to electronics for more years than I care to mention, having managed an engineering technology centre for more than 30 years. My current interests are more on the musical side of electronics particularly amplifiers,digital mixers, electronic keyboards and organs including church organs. If you think I can help contact me any time. Cheers Shawy

I know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.
For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

We're going to try to focus this as a Turntable setup (his turntable is a seemingly cheapo from like 10 years ago...but it does have a phono out), which is at least comforting because the amp has a phono input. It also had a USB port, looks pretty cheap
I'm trying to go for an all analog here. What is the likely problematic caps? Power? I've never dealt with amps this old and of this type. I replaced them in a cheap yamaha... -
I am not ashamed to say this is my first FM alignment I have ever done. I am well versed in electronics and repair. Been doing it for many years on Pro Audio Live sound equipment. Worked on Power amps EQ's musical gear and Large format Mixing Live consoles Etc. But now I can see this is a whole different world when it comes to tweaking this kind of gear. I do have the proper gear like the SENCORE SG 80 and HP Generators and Scopes Etc.
Look below at Adjustment 12:8. The Null adjustment. I have a Heathkit IM-28 VTVM that was rebuilt and has new Burned in tubes that I used for this...12-30-2024, 03:18 PM -
Dear all,
For a friend I'm trying to repair an Acer Swift 3 laptop (SF314-42). I'm not a professional, but have some experience (both as amateur and professional) in working with electronic design and repair of musical instruments.

It was bought new and used (not heavily) at home for about three years. After normal use, it was put to sleep, connected to charger and left over night (just like any other day). The next morning, the laptop would not wake up from sleep. Instead, when pressing the power button, the power... -
