The Nagras were, of course, the KING of field recorders. Nothing else even comes close. BUT....they were prohibitively expensive, being at least...
The very BEST noise reduction system was Dolby SR, a professional-use system issued in 1986.
"The 35712 head in the manual that I have...." What manual is that? None of the manuals or supplements I have seen show that head number.
dotneck335: "The highest serial # with a "pointy" head I have found is #53613. The next serial # I have found is #72265 and that has the rounded...
The highest serial # with a "pointy" head I have found is # 71236 :. The next serial # I have found is #72265 and that has the rounded 35711 head....
Does anyone know the WM-D6C serial numbers affected by the Dolby circuit changes specified in Supplement 1 (January 1985)?
"However none of these supplements say anything about the 3 head versions." HOLD THE PHONE!! There's a 3-head version of the WM-D6C??
Also, the WM-D6C gen 3 is listed as release year 1996 and gen 4 as 2001. These are incorrect. Supplement 2 was issued in March 1994 featuring the...
I have noticed that, in your timeline for WM-D6Cs, you gave versions 2 and 3 with the same serial # range and everything else the same. What then...
Good to know that the tantalums on the WM-D6C are not problematic. But the other concern is that tantalums are also known to color the sound. I'd...
Thanks for the info. I was also wondering about the bias frequency of the WM-D6C. I read somewhere that it is 75KHz, but the bias trap on the...
So what is the difference between the "pointy" amorphous heads used on early Sony WM-D6C Walkmans and the "regular" amorphous heads? Is there a...
What I would propose for the WM-D6C is to cut that trace which leads to the jumper wire that feeds the CX20084 just where it joins down from the...
Valentin: "In regard to the diode I attached a picture. The simplest way I see is remove that jumper wire and add the diode there (it may require...
Sticker color change was made in 1988.
Thanks for the replies! Has anyone measured the inductance of an amorphous head on a Sony WM-D6C?
So EXACTLY what is the difference between an amorphous head and a permalloy head?
So I have been watching WM-D6Cs for sale for a while now. Seller don't always post the serial #s, but I have noticed that the ones with WHITE...
Yes, I see that the 15Ω resistor will influence the output impedance greatly. But, 100uF still has ~53Ω of reactance @ 30 Hz so it will still...
For C607, I found this one: a Kemet ESS476M016AC2AA; 47uF 16V electrolytic, 105C 1K hr; 5 mm D x 7mm H x 2 mm LS @~ 92¢ each. C138 gets confusing...
