I just bought a Pioneer Stereo Integrated Non-Swiching Amplifier A-7. Very good for Pioneer tremendous sound machine, power, very low distortion, very complete, does not heat up almost nothing to operate and beautiful design to delight the eyes. A very well built strong amplifier with its 37 years does not have any noise when operating its controls. Speaker connectors are excellent professional Banana type. As it does not separate the Pre-amplifier from the power stage, if you want to insert an equalizer, you must do it using one of the two inputs and outputs for cassette deck and it will work perfectly (Pioneer included 2 connections for Deck with that intention) The system Protection Power output works very effectively and shields this equipment from almost any damage due to improper speaker connection. The pictographic panel includes all the information of the state of the equipment and in very beautiful and easy to understand. It includes a great pre-amplifier for MC cartridges, sub-low frequency filter, mute control, direct output selector and a simple and intelligent power output indicator with 7 LEDs per channel that indicates output powers as low as the one used to listen with headphones and as high as 70 watts per maximum output channel, without having to select power ranges. In conclusion a magnificent amplifier that Pioneer designed 37 years ago to last much longer ...

I have this amp and love it. But is it possible to hook up a Pioneer equalizer to this amp? The amp does not seem to have EQ in/out. But it does have play/rec phono plug inputs in the back for two different tape recorders.

Im a long term tube guy and i was really surprised how good this amp is. Large sound stage. Natural sounding and not dry. Clean, fast, tight and extended. Tight bass. Midrange is not up to best tube amps but its good. Most of all musically involving and easy to live with. Purchased used, mine worked perfectly, but its a complicated circuit and i wonder what experience others have had with this 1980 unit.

re: A-7

@jazmaan ask yourself this question . "Do you really need an equalizer ?"
I too own a pioneer A-7 and it's a remarkable amplifier . The sound is pleasant warm like and has good punch for bass . .I brought back mine from the dead . It was blown on both channels (output transistors) and seemed trouble some to fix as pre amp board was not diagnosed thoroughly. I sent it to a technician . He fixed it up well it's back to life and still sounds great . Maybe a recap will make it sound even better as this unit is 37 years old
Yes it is possible to connect an equalizer to this amp but many of us have been there tried it (buying and equalizer ) and most of the equalizers are just put aside and neglected later .
Your amp is the equalizer . The sound it gives is just great with the basic tone controls .
Think about it . Do you really need one ? You won't stop playing with the adjustment levels if u do go in for one . Just my honest opinion. Cheers

re: A-7

Very lovely warm sounding amp . You can even enjoy the sound at low volume and moderate levels . Very beautiful natural sound . I have never heard a tube amp but some say here that this amp feels like tube and I am therefore happy to have it . Currently it's undergoing major repair s . Cannot wait to get it back. Goes perfect with my pioneer hpm 700's

re: A-7

six months listened to the pioneer amplifier Pioneer A7, before using the electrolytic capacitors checked, all normal. volume controls , tone controls and switches were cleaned and lubricated with silicone grease .the sound source C. E. C. CD3300 and Technics SL 1200 . the sound is decent . built-in Phono stage beat homemade tube Phono stage .
