I watched Brads video of the replacement of some Bosch pick up coils with a Yam CY-7 replacement.
I know this was as replacement in an older Bosch pick up system but wondered whether it was an option in the Kokusan pick upped one.
The issue maybe that CY-7 coils have a 200 ohm resistance where the Kokusan have 100 ohm. Now I dont know whether that matters- maybe the Bosch units were also around 100 and the CY7s worked in that situation, so that coil resistance might not be critical. Anyone know what the Bosch units were?
But for 20 quid it might be worth a trial.
