Hi KI
Many Thanks, Attached is a wiring list for the Head block 25 pin dsub Socket on the deck.
I have wired a staggered erase head as per the list, I took it that Blue on socket = Brown on headblock & Black on socket = Black on headblock.
So Yes, Blk on 13 Brn on 12 Channel 1 & Blk on 25 & Brn on 24.
This now works fine, and yes the EEEC1 & 2 errors have now disappeared, and is recording perfectly.
All I need to do now is re-align the electronics as the output is now noticeably higher than with the 317 2mm heads.
Next is to remove the R/H TC head and both TC pcbs.
Thanks KI for the info. lucky I had staggered Erase Head!!
Will report more later
