Hello,
This is my first post on the Quadraphonic Corner and looking forward to absorbing some advice from people with the same interest and passion that I have for these old quads!
I bought a very nice looking Pioneer QX 8000A off of E-bay that was listed as "works great..I am listening to this unit as I write this listing".Well...it did come on and 2 out of the four channels were working!
I took the QX 8000A to an electronics repair shop that was recommended by a co-worker to get an evaluation.Got a call back from the shop and was told that a number of things needed to be done to bring her back to life.First all about 7 bulbs were burned out,no big deal,pots were dirty and needed cleaning,no big deal,tuning dial string needed adjusting,no biggie and then the bad news...the capacitors on the QX boards were dried out and needed replacing.He also told me that it would be a HUGE job to replace the caps in the QX boards and that he would charge around $500.00 to do it.Of course I said no...(kinda sounds like he just didn't wanna mess with it to me).He then said that he could "jump" the two amplifiers with an RCA cable at the tape record and monitor plugs and keep the selector in "2 channel" mode and I would have 4 strong sounding speakers.Well...I agreed and got it back a couple of months ago....been sounding pretty good until last night.
I went to listen to some vinyl and noticed that no sound was coming from the right rear speaker.I checked speaker connections,speaker fuse,changed speakers,with no difference.I turned off the Quad in dissapointment and left the room.I went back several hours later and tried it again.IT WORKS NOW!!!!!...for about 2 minutes and then the right rear channel slowly fades out with distortion and finally dissapears.All other speakers are loud and clear....
Could jumping of the amplifier have caused this?Why has just one speaker on the same side quit playing if the amps are jumped together?
I would really like to keep this quad because when it is working it sounds amazing.I would even consider paying hundreds to get her recapped if that would do the trick.
Any help would be appreciated:banana:
