Don't know where you buy them over there, but Philips (now BC compts) have
VR25 and VR37 5% ranges rated at .25W/1600VDC and .5W/3500VDC respectively.
Catalogue values here are 1.2-10M for VR25 and 1.2-33M for VR37. $.20 ea.,
sold in multiples of 10. If all else fails, I can get them and mail them to
you.
