Hello Robert.  My HW-101 uses Potter & Brumfield KH-4076-1 relays 
(manual says Heathkit PN is 69-35).  Coil resistance as measured with my 
VOM (relay out of the circuit) is 4.7K.  A search on the internet comes 
up with someone saying they are rated at 240V coil.  Don't know exactly 
where he came up with that.  I got a couple on that e-Bay site a couple 
of years ago.  Hope this helps a little.  Have to tear my HX-20 apart to 
see what is used there.
