Hi,
I recently bought an old ceramic element from the early eighties off ebay. I know you have to be careful when doing this, but it wasfrom music store clearing old stock, and was only £20. Anyway, the seller put two wires on for me, because of the risk of heat damage, but I've had to put a secondary negative wire on linked to the pot.
I have to say, as an owner of the 520DX and Bluesblaster, I am not overly impressed by this mic. I see many threads with people complaining that they've ruined their crystal elements. But how do I know if I've damaged by element with heat - would it stop working altogether? How much heat can ruin it?
Many Thanks, harpburn

When these elements are new they have comparable, if not greater output than your other mics. But unless you're a ham fisted solderer with a big iron, the chances are it went bad all by itself sitting on the shelf. There is no way to tell after the fact.

Thanks Greg. Ah, yes, the output does seem a little low. If I compare it to my green bullet, full volume on the JT-30 is like vol a quarter way on with the bullet. But it is a ceramic, aren't they significantly more durable than crystals?

Ceramics do not in fact seem to be any more durable than crystals. Again - they are really BOTH made from man-made crystals - what they call "ceramic" was just another formulation.

Thanks, Greg. I found your PDF very useful, btw, it was an eye-opener to someone who does not know much about elements. So am I right in thinking that there is no way to really tell whether or not mine has gone bad since it was built, unless it stops working altogether?
