Any old school pioneer experts left ?

Hello
Going back to the early 80s a head unit called a pioneer Kex-73 was at the time the nuts , now I know you can use an amp called a Gm-120 and a Gm-4 BUT does anyone know of any other compatable amps that will work.
Thanks Paul

Any of the gm range from that era had the din plug that connect's to your head unit.

Or you can get the din to phono adapter and use any modern amp that you want. There are also a number of amp's all different makes that accept high level input (speaker out from your head).

yep argee with zaust get the din to phono about £3-5 and run a moden amp , there still are a few amps that still run the din plug ,

Cheers Fellas ,
I thought the large type 8-pin din plug on these old pioneer sets is different to all other din plugs because of it's size ?

like on volvos head units , there amp out have 4 pins for audio and 2 for power (+12 , rem) test with a meter or look for pin out on google

Thanks for helping fellas but this time it seems these old units are different......or so I am told.
Apparently these early pioneer head units get ther power through the amp and not the other way round,so that makes a specific pioneer lead from that era necesary and in this case a normal din to phono wont work ?
What do you think ?

well it is possible to make a din lead , that the frist i heard of a headunit that gets it power from the amp. as i had a look at that unit and it ready has power leads cumming from it.

blue wire is auto antenna (remote turn on)
yellow is + 12volts consant
orange is + 12volts key live

the system is grounded via the antenna plug or better still run a wire from the body of the system to ground.

once system is running check the din plug for voltage anything around 0.2 volts DC is output. how many pins are they? 4?

Sati
You are right but all these units only work / power up once connected to the amp.
Strange but true.
Thanks anyway mate.
