Hi Guys
I'm new here and hailing from Cape Town, South Africa.
I recently acquired an SCA-35 so I guess this is the right place to learn all about them.
My amp was totally unabused and must have been stored in dry conditions for quite a few decades as it shows little usage.
Since I also own other tube equipment (a Leak Stereo 20), I was careful about connecting it to our 220V ac and did so gradually through some 40, 60 and 100W lightbulbs.
I have not replaced any caps or resistors but have given it a thorough dusting, fitted a new ac cord, a new flush-fit fuseholder,replaced the panelmount on/off switch, repaired the balance pot and replaced the amber power light lens with a little blue number.
Its performance in my system is good enough for now but there are two issues which bug me:
If it is connected to the ac and switched off, I can feel a slight 'vibration' if I touch the chassis or faceplace. On switching on, the 'vibration' disappears.
The other issue is a bit weird. If I pick up the amp and move it fairly vigorously from side to side, I can 'feel' something heavyish moving around. Could this be loose transformer bobbins?
During initial cleanup and inspection, I also checked for loose screws everywhere and found virtually all of them needed re-torqueing.
Happy and prosperous New Year to All
