Title: Schematic Diagram for Amps: Where to Buy?
Post by: C.O.2 on Nov 22, 2005 at 09:13 AM

 ??? Hi bros. at Pinoy DVD! Ask ko lang where to buy schematic diagrams for amplifiers especially vintage amps.  I am planning to restore a vintage Sansui qrx 3500 at my neighborhood repair service but he's asking me for such.  Can anybody there help me please...  :'(

During the 80s, I used to get some schematic diagrams of amps and TVs from a shop in Raon.  Don't ask me exactly where, as I've totally forgotten.  But if you can scout the Raon stretch and ask around, I'm pretty confident there's one or two who still have them.  The Sansui Qrx model is rather old, maybe in the late 70s, but they may still have them.  Good luck.

HI.

They still sell Schematics at Deeco in Raon. A few months ago, i was able to get a copy of the schematics of my Pioneer SX1250 for 50 bucks. The copy was clear enough for me to adjust DC and Bias of the receiver. You might get lucky and find the schematics for your sansui quadrsonic amp.

regards,
Lordfoo.

I also bought some diagram few months ago lang, i think eto nga ung tindahan.  You must have the board
number as reference. Kung wla ung model number.

Para syang isang bahay lang na may maliit na bintana(Chinese ung bantay) na maraming tao na bumibili araw-araw... Pero inside napakalaking library ng mga old and new schematic diagram....
