Hi Ulli,
Look through the fins.
4CX1000A fins are internally flat.
4CX1500B fins have small convolutions in each fin.

Hi there,
Can someone tell me, how to distinguish visually a 4CX1000A from a
4CX1500B from outside ?!?
There is no printed label anymore visible. The tube in question is used
and comes from a marine equipment manufacturer DEBEC (Germany)
Is there any difference, so that looking on the tube we can definitely
say that it is a 4CX1000A or 4CX1500B ?!
Is there a sinple electrical test probably so we can find out ?
Please let me know.
Thanks for info.
Ulli, ON5KQ
