Am surprised no one mentioned that the D104 was made with two types of 
elements, crystal, believe they were Rochelle salts or something like that 
and ceramic. If I remember correctly the ceramic was the D104C, had lower 
output and could withstand heat and rougher handling. I copied Tom's J310 
post and drew a diagram, it looks good and the values check with the J310 
specs. Time to get the old D104C back in service.
