Hello everyone.
I'm Ronny. I have known this forum for a long time and have been able to use the information in this forum several times in the past to solve problems in my own projects. Especially references of current transistor models to already discontinued transistors could help me a lot. Now I want to be part of this community to help others with their projects and maybe get some support for my own projects in the future too. I am particularly interested in integrated amplifiers, power amplifiers and tape decks.
In the past I have mainly restored various Harman/Kardon amplifiers. For example, a PM665 where one of the power amplifiers stopped working, or an HK6950R where only the switches and controls needed a good cleaning. I was also able to successfully repair a Harman Citation combo consisting of the 25 and the 22.
A less successful project was a Harman Kardon HK770, where the well-known corrosive glue had unfortunately attacked the circuit boards too much for my skills.
My current project is a power amplifier from Luxman (M-02). Here one of the two channels is defective and generates a DC voltage at the output. Let's see if I can find the fault there...
I hope my presentation didn't bore you too much.🙂
Greetings Ronny
