Genuine Cetron 572B's are out of production. There may be some new old stock out there, but expect to pay a king's ransom if and when they surface.

The clone 572B's come in a range of quality, mostly mediocre, and none are as good as the original. Here's an article you may find interesting:

You can buy chinese 572B's  from  CTR engineering..which is owned by  W8JI.   He tests them, and weeds out any duds.

Read through the detailed info.  This is as good as it gets.

I have a -2100Z and a few Cubic 1500Z-series amps. May pick up a couple sets for future use even though these are all still full output.
