Hello,
I live in British Columbia, Canada. I have been learning about electronics for the last few years, mainly focusing on audio amplifiers. I am fairly comfortable with tube technology, but solid state is still relatively new to me. Here to expand my knowledge and experience.Comment

Hello, I am new, and I would like to introduce myself as Illbbe.
I am a relative novice who like to tinker and to recycle or repurpose all types of typical retail machines that have been thrown away.
Many machines that are discarded require repairs or have an issue, and so I seek to resolve these as I come across them.
In my research I have stumbled onto this forum and I appreciate the conversations and contributions from the many talented and knowledgeable contributors.
I will in good faith also contribute if I have something to add.
Thank you

Hello friends, it’s James here, have been lurking around this site for some excellent repair information. I was unfortunate enough to have some water damage in my house. This resulted in a little bit of water in some of my Apple computers. Hoping to share some repair information I gathered over the years and also gain insights on how to check the A2485 logic board and fan PSU for issues.Comment
