thanks kev for asking around on my behalf and thanks to all for your ideas especially chris for the very informative reply.
I have a 19 set in the Cromwell and was very keen to get the intercom working as we need comms to safely operate the tank, unfortunately my capacitor failed the first time it was powered up, no explosions but it got hot enough to start leaking brown fluid from the bottom of the case, I could have switched to vibrator but was advised not to by some guys who often use 19 sets as it was prone to failure. I have been trawling the net this evening and cam across the 19 set forum who are offering a solid state vibrator for £15 which I will order. I have also bought a 30uf capacitor from ebay which was rated at 450v A/C but could anyone confirm if this is ok with the dynamometer. ie does it produce AC or DC.
I look forward to hearing the replies as the radio is a really important bit of the tank which is often overlooked during restorations, plus in the short time that the capacitor worked we managed to get the world service on the headsets which was really cool, it sort of made the tank come alive in a strange kind of way.

cheers

rick

lol I have spent many hours pouring over the pics and trying to find all the ces. I have the "Cromwell tank vehicle history and specification" book which is the Cromwell bible, if you don't have one then get it

That will be a phase shift capacitor for an AC induction motor and will be perfectly OK for the job. The only things that matter are the capacitance value (and 30 is easily close enough to 32, especially as the electrolytic capacitor tolerance is something like -10/+50%) and the voltage rating.

The dynamotor produces DC with a certain amount of commutator ripple on top, and the capacitor is there to flatten that out and prevent a whine on the set audio.

Best,
Chris.
p.s: Nice tank! (If I didn't know better I'd have accused you of having pinched it off the production line.)

thanks chris, comms always seem to be a bit of a dark art to me, even when I was in the army I never really knew what I was doing !

the Cromwell is a real beauty to be sure, it's just a shame it nearly bankrupted me doing it
