Just replacing the capacitors on the turn table motor of my D33A and was just wondering if I have the reading and convertion right I think the big one is 1.1mf and the little one 0.2mf does thisconvert to 1.1mf = 1100μF 0.2mf = 200μF

1.1mF will be 1.1μF in today's units. So 0.2mF will be 0.2μF (or 200nF).

Thanks for the advice just wondering if anybody knows where to get 1.1μF capacitors for HMV model D33A Turntable or is there an equvilant ?
As all I can find is 1μF

You will find 1μF is ok. My email is unhidden.

I would be using mains rated caps for this particular application & also the exact value too.

So I would use a 1μF & .1μF in parallel. Don't worry about the size - the new ones are much smaller than the original.

I'm guessing the original caps are encapsulated in wax on the motor unit?

Yes they are the wax coated ones thanks for the advice I will go the parallel option as 1.1μF is an unusual value and had to find
Thanks again
