Hello,
i'm the proud and first owner of the Technics set since 1992 and it has not been used since 5 to 7 years. I wanted to pass it on to my daughter and installed everything. At power on i noticed smoking coming from the amp and after 5 seconds i turned it off again. I opened and cleaned everything. Then i did another power on and i noticed smoke coming from the resistor marked with R573. It's located close to the fan, see pictures. I further cleaned that specific spot and switched in on again, and off when i noticed the resistor itself is burning and becoming black. In total i had 3 times power on, two times just for a second or so. As far as i noticed this is the only malfunction and the display and response was correct. I didn't play any music but i am confident it will.
I guess i am looking for the confirmation i can do without this resistor, than i would need to know what it is for. If it's critical for the planned usage i need to find a way to replace it. Though i'm a amateur (no engineer) i think i should be able to do the job myself.
The set will be played for playing streaming (spotify) from the an aux or dat input. No cassete, no cd, maybe radio. So i will only be using the amp and radio components. If it's only to operate the fan, than i could think of another way of cooling it or instruct my daughter not to use it at high volume... hmm this sounds very risky ;-)
Thank you very much for your support!!
cheers Wouter
