Bought this QX949 after returning from duty overseas in 1975. My son uses it as his studio amp. Still a great sound. I have an SX737 that I bought in Germany. One channel no sound. Possibly the relay S1. Any idea what the cost of re-capping the 737 would be? Thanks, great site.

This 949 sounds fantastic. I use it as my benchmark for sound quality. I run it in stereo only.
Hi quality Caps used oem nichicon and enla's. Only 1 bad from 1974 in the low pass. it's cram packed so recapping take lots of time.
Mine sounds so good I will not recap.



re: QX-949 low pass filter button

Anybody experience problems with the low pass filter button and know a fix? Is it just dirty or more serious? Big pop and rumble when it is not pressed.

Pioneer QX-949 Owner's Manual

Can anyone please help with an owner's manual for this beautiful receiver. It is quite difficult as compared to most other non-quadrophonic receivers and because it is the Q version and not the S version it even makes it more difficult. eBay wants 60.00 for the manual and I will not pay the vulture a dime. Oh yea a knob will cost you $25.00, but at least its cheaper than the manual that he is photocopying and sending copies. I do not mind paying, but I will never pay vultures.
Thank you, John

AAAHHHG, The QX-949 I own, must be the "red headed step child" as far as Service Manuals for Quad Receivers is concerned. You have the QX-8000A and the QX-9900. You did save me some time though, because if you don't have one.....Nobody has one. Very Nice Website!!!! MIKE

re: QX 949

I recently did a complete QX-949 restoration for a local guy. I replaced and upgraded over 250-parts. After it was finished, it sounded great, but for the time and money, I's stay with 2Chan SX-series receivers.

I may have some additional qx 949 stuff I could add-I am new to the site and uploading scanned images so I will try to get something posted by the end of the week for this quadraphonic receiver.
