Home Tube DIY Asylum

Do It Yourself (DIY) paradise for tube and SET project builders.

RE: thanks DF ...

You got it!

Incidentally, there are reports of early failures
regarding the use of 12BZ7 tubes.

Plug-and-try, it seems, is not doing the job.
People have simply plugged these into circuits
designed for 12AX7, etc., and see if they
hear something-- different. Trouble is, what are
the new operating points now? DID THEY CHECK THAT
against 12BZ7 Design-Center values? AND, try to
operate UNDER THOSE?

Just plunking a different tube into another tube's
circuit isn't useful tube life data!

The tube is no different in build quality than similar
types made by the same tube factories. Why would one
age faster than another?
It's operating points and nothing else.
