I am trying to locate a schematic for an old (possibly pre-WWII) Executone intercom. I am unable to find a model number but the tube lineup is 35Z5, 12SJ7, 50L6. The cabinet is wood and the Amplifer sits atop a line selector switch which contains the ring tone buzzer and pushbutton switches to select between 11 lines.
Do you have an archive of these early units or, if not, could you suggest anyone I could contact who might?
I might be able to help. I have an exutone intercom amplifier as well and I was looking all over for schematics for a while. Then I decided to open the thing up. To my amazement a schematic was glued to the bottom plate inside the chassis. Other than that if you know the model number perhaps we have the same one, in which case I can scan mine and send it to you.

My question is, do you hear music when you play a record, or is only "wind" coming out of the speakers?
The player was build in 1964 with Germanium transistors. These transistors are known for their noise level. But in those days nobody noticed this, because all transistor amplifies had noise.
If there is no sound at all, only noise, it can't be that difficult to repair the amplifier. There must be some schematics around on the net. Be aware you need a Xtal PU element and it won't be easy to get one of these.
I found an interesting page on the net. It is a pity the schematic is not 100% clear. 3006 Mk Player Ferguson Radio Corporation Ltd London
It's possible that there's a broken wire in the cable that connects the foot control to the machine. This usually happens near the plug that plugs into the machine, or by the end that goes into the foot control.
You can usually duplicate it if you put the auto-backspace up a bit and then hold down the play pedal on the foot control. While holding down the play pedal, try moving the cable near the machine or near the foot control in a circular motion. If the machine stops, rewinds or fast forwards, then odds are that the problem is with the cable.
I have found conflicting information on this recorder. According to product specs on Amazon.comUK This recorder has no computer connection.
If this product description is wrong you should see a USB connection somewhere on the recorder. Just connect the USB cable from recorder to your computer. If you did not receive a USB cable with your recorder you will have to buy one. You will have to determine if you need a mini or regular USB cable. Then double click on my computer. You should see the device listed there. Double click on the Sony device icon. The files on your recorder should now be showing. You should then be able to drag the files to a folder of your choosing on your computer.
