    This is the 2nd Sansui 9090db I have had on the bench in the last 6 months, as well as a complete rebuild of a G-9700 in between. This 9090db is very strange. After complete cleaning and deox i powered it up on Variac and was thrilled to see it come out of protection mode right away! I have...

    9090DB, only tape 2 works

    I've got a Sansui 9090DB that all the inputs are quiet except tape 2. Tape 2 sounds great. Is this still a Dolby board issue? What I've done: de-oxed switches multiple times and connections in back, audio is better every time but only in tape 2. Dolby board pass-throughs reflowed with...

    Sansui 8080db hum in Dolby only

    Hello everyone. I'm working on Sansui 8080db. Originally, it was (you've guessed it) stuck in protection mode. Resistor replacement on the driver board and all 4 outputs took care of that. Next problem found once out of protection was no Left channel. Sound was there just barely. Found it to be...
