Have you any experience with the HansPeter Roth (HPR) alignment test tapes?

"I would like to know when the V shaped head was replaced with the "32711" head by serial number. " Good question. What I have found so far is...
I'm still trying to find the serial #/dates of the transition from brown to green PCBs and the same for the Dolby chip change (20068 to 20218).
On those early PCBs with the 20068 Dolby chip, they appear to me to be brown on the component side but green on the solder side. Is that right?

Thanks for the info. Looks like the permalloy 35712 head came later than I thought. No clue about the 'E'. 'Europe'?
Well, that would be a question for a REAL expert on WM-D6Cs. Like Valentin. or Deb64.
In all my research, I have NEVER seen a serial number that high----highest has been in the 50xxxx range. Got a picture of it?
Thanks, I'm sure that will help. One problem, however, is that the Dolby chip change (and PCB update from -11 to -12) would only be visible if you...
For Sony Walkman WM-D6C, I am specifically trying to find the point of serial #s at which the PCB went from -11 (Dolby chip CX20068) to -12 (Dolby...
What are the serial #s of your units? I am specifically trying to find the point of serial #s at which the PCB went from -11 (Dolby chip CX20068)...
