I mod'ed the Denon PMA 1500AE, by adding a loudness circuit. Thanks to @pcbwayofficial.bsky.social @queenelaine.bsky.social for sending and sponsoring me with PCBs. youtu.be/dBOXJuC_H-c?...

NAD 7120 Stereo Receiver from 1983. Fixed the dead radio. Blown transistor replaced supplying 12V. A nice feeling to be able to bring it back to life after 30 years.

Aaaand it works again. Re-flowed solder joints. Replaced output transistors. Adjusted quiescent current.

Re-assembling the stereo amp after fixing it. It's a puzzle to put the boards together with wires and screw.

The Wave 1981 Just recalled this movie name. Been thinking about it a lot lately, but could not recall it. My teacher showed it to us in secondary school. The movie sat with me for a long time. youtu.be/4qlBC45jk3I?...

My C64 keyboard PCBs just arrived. I was so excited, that I have cut my thumb, when I opened the package. The small pcb is for making it possible to use a ribbon cable as keyboard cable without crimping.

Measuring key parameters on MOSFETs. Vgs(th) and Rds(on). This should tell if it's the real part or not. Turns out, they're OK!

First homemade cherry mx keycaps. Laser engraved. It is not perfect, I would like it darker. But it looks quite clear and it is faster, than I thought it would be. I used standard (DSA profile) blank key caps from AliExpress.

Good news. My Denon PMA 1500R is now playing again. Reflowing solder joints in the night!

PetterHans @bwack77.bsky.social · 13/01/2025

While measuring, it kept coming back to life. Sure enough, cracked solderjoints seen in this area. Also tarnished resistors.

My colleagues laptop bios password reset. Another laptop from 2016 is not going to waste. The sane can't be said for newer laptops with bios locked and lost passwords?

Denon pma repair. Class AB amp. Scope shows positive and negative DC levels before push pull transistors. Good. Left channel, ok. Right channel dead. No dc levels, no signal. Seems to change when warming up.
