Hi all,
Excuse my bad english because I am a french guy, new to the board.
I am fond of Binson echo, those wonderful pieces of italian technologies. I own a Binson PE603-t solid state and a 60's Binson Echorec 2 tube unit, model T6FA.
I search for informations on the net for years and, let alone the site where people sell the schematics and manual ( :evil: ), I came up with good information such as some operating manual and schematics (PE603 and echorec). I saw few topics on the net and on this forum about Binson, so if anybody is interested in some informations, let me know.
Here is the echorec schematic (just clic on the picture):
Now I have some problems with my Binson Echorec, and I am sure you guys can help me.
Here are some picture of my unit:
Now, the problem is that the drum and the macnetic heads are in bad conditions. I have been offered a complete new plate, with drum and heads, but the new heads have an impedabce of 340 ohms, while my heads are 640 ohms.
I tried one new reading head (of 340 ohms, the other reading heads and the recording one were the original one of 640 ohms) and the signal is nearly inaudible, there is a big drop in volume.
So I wonder if there is a possibility to adapt those new head to my machine. There should be a possibility to bias the heads, but I don't really know.
From the schematic, I understand that half of the tubes n°1 and 2 amplify the signal of each of the reading head. But what do I have to modify to make the new heads work with my binson? A resistor, a capacitor? Nothing (ie perhaps that there is an automatic offset with the recording head and there is nothing to change if the recording head is also 340 ohms, just a suggestion)?
I would be very grateful if someone can help me.
Thanks in advance.
