David if you still need the manual, I'll scan it and forward it to you.
sorry for the late response but I've had no chance to get at the keyboard

Subject: [TechAssist] Technics - Integrated Amplifier - SU-V98 - Powers
Up - No Output
Hello All,
This unit turns "on", display is present and I can select different inputs
yet there is no output. Main output IC is one of those SVI-3205 (replaced by
SVI-3206), I've worked on a couple of these in the past, one where the
outputs were blown (this caused main fuse to blow), the other unit required
extensive resoldering. In this case I don't hear the speaker relay engaging,
this should occur a few seconds after power "on". I've resoldered all
questionable ring cracks in and around power resistors, diodes, etc. and
still the relay doesn't engage. I could use a service manual to further
debug this problem, unless of course one of you have experienced this same
problem, please do tell.
God bless you all,
David Lessard
