Most of it is over my head so can't comment, you've made me think though, I have a good quality ( I think) multimeter I'll have to look to see if it measures frequency.

Bob, I've got a frequency meter and other meters. If you ever need a hand ....

Thanks Rog I'll remember that though I'd have to learn how to use one. My voltmeter is an aging Megger AVO 310 and these days I have to get the instruction book out when I need to use it.

Whereabouts in the 110v world are you?

Thank you for your kind words. I have learned a lot about woodwork from these forums and the assistance I try and give in return is in the form of using my electronic/electrical knowledge to provide information and support like this. It has a second benefit to me as it helps keep my mind active in retirement after a career of problem solving in an electronics research company http://www.roke.co.uk
As for the 110v version, the motor and its capacitor will be designed for 110v but the controller I would expect it to be very similar to the 230v design simply with a different value of R4. This is a component most likely to fail due to heat dissipation and when it fails the resistance, marked with coloured bands, becomes difficult to read.
If you are willing to open yours up, just four screws, and take a nice sharp photo of the circuit board I would be able to look of any differences in design and possible update my paper to assist Hegner owners in the 110v world. Without that I'm unlikely to get access to a 110v machine from here in UK.
When opening it, the leads from the tacho generator (thin black & brown) may be quite short and may well disconnect from the circuit board. In fact to take a clear photo, these need to be removed.They are simple push on connectors onto pins on the board and can be replaced either way round.
If you do take some photos, please mail them to <motors@minchin.org.uk>
