Ampex 600/601 Mic Pre with a Input transformer..

This is a Ampex 600/601 Tube Record Playback electronics from a tape recorder .
 No input transformer, there is a metal plate where the input transformer can be added .
The transformers are good and the in sides are in very good condition.
I do not have the power cord for the unit , and is sold untested .  Sold As Is
I have been on the road for the past few months buying up large amounts of vintage tube audio gear.
I will not be able to test every piece so I am selling items under $500 untested.
This item looks good , but should have its caps re-placed as they are over 50 years old ..

I have received a lot of questions about the 600 series Ampex I have for auction .
 I hope this info helps clear up some of the questions.
These units are tape record playback electronics as I state in my auction. They have a built in mic preamp as well.
The hum adjust is just what it says to lower any hum. The Bias control is to change bias on different type of tape. The rec cal is the tape record calibration. The PB level is the playback level . The PB Equal is the playback equalization.
Unless you are using these with a tape transport they are meaningless..( except the hum) I have added a photo of the other end of the unit so you can see the AC power in and the line level out (1/4" jack) as well As the line level in(1/8" jack) ..
You plug in the mic in the front , use the mic level control and the line out for output. There are all kinds of mods done to these units, from just adding a input transformer ( this one has a  input transformer ) to adding different output transformers , using the headphone out as unbalance out signal to striping down the chassis and making it into a dual mono unit. This is a DIY dream machine.Do a Google search on, modify ampex 600 for mic pre, you will be reading for hours. I would not call these units plug and play. But great units to learn on and tinker with.. Read Read and read , as there are lethal voltages in these units...Be careful..
