Hi Dave,
Yes the line time base looks pretty similar as for the PYE LV30 except the noval PY and PL types. They dont re-invent too much on this
For radiograham hereafter the link to Conrad UK, for the resistance wire I used for my restoration.
https://www.conrad-electronic.co.uk/...=mainSearchBar
In case this link doesn't work, the item no. is :429031-89 resistance wire 28 Ohms/m for 5 meters delivery. I recommend not choosing an higher Ohmic value, cause the wire will be too thin and will not survive for long the heat.
This one seems to support the stress. So good luck foro the rewinding
Hope that help .
Roger
