    Getting a high voltage reading on the F-2619 board of my 9090DB

    Initially this 9090db was getting no FM or AM reception, and after doing some research found that the F-2619 board supplies 12.5V to the tuner section which wasn’t being supplied because of poor solder connections on the heat sink and TR01. After resoldering the connections properly I made the...

    Fear the 4ohm speakers i just brought are not a 100 percent match with my 9090db

    From the reading I've done I don't have a good feeling hooking up my recent purchase of Ar3a speakers to my 9090db .  I recently found a brand new Adcom GFA 6002 Power Amp. for sale at 300.00 dollars. Would buying the Adcom solve the problem to run the 4ohm speakers with my 9090db ? Does the...

    Hi everyone, I am looking for an AK tech to help me get my 9090DB repaired. I got the receiver about a year or so ago and replaced all caps with the exception of the filter caps. The common issue of one channel not working because of the Dolby board is too much for my expertise. I tried...

    This is the craziest 9090db on my bench. I have done around 40 of these in last couple of years. Rebuilt this one and shipped it to client, who, after a couple of weeks realized it was playing only right channel. It is not the Dolby board, again I have rebuilt 40 of these boards. I have never...

    Sansui 9090DB + QS-500?

    Right now, running a 9090DB through NLAs and have no complaints. But I’ve got a line on some Heresy IIs and don’t think I can resist. So: if I’m not all that interested in looking for quad vinyl, etc., would a QS-500 add all that much beyond four more cool VU meters? Also, given the 30 wpc...
