"Gilbert Bates"

Look at it from an engineering perspective Skipp.


** The lying cretin has no idea what that is.


High potting in the commercial / manufacturing environment is
typically used for design and compliance *verification* and not pass /
fail *testing*.


** Correct.


The max rating for a 6L6GC is 500V.


** No it is not.

That is a max *plate supply voltage* figure for a particular set of
operating conditions.

It is based on NOT exceeding the plate or screen *dissipation* figures in
normal amplifier service.


The EL34 has an 800V max rating.


** Again, that is a *plate supply voltage* for a particular set of operating
conditions.


If any tube does not perform to it's published specs, then don't use
it. I don't care if it was manufactured 60 years ago or yesterday. A
6L6 or EL34 should perform to its published specs, even if those specs
come off a datasheet that is older than your grandmother, otherwise it
is not a 6L6GC, EL34 or it is simply junk. That's the point Phil is
making.



** Skipp is hung up on the term " high-pot" - he does not understand it
PLUS it is being misused by shonky tube vendors like LV to make a fast buck
from gullible musicians.

In any case, no matter what electrical test a tube passes when it is brand
new - it likely will fail in host of horrible ways after months or years
of service in a guitar amp.

This is the INHERENT problem for the MM transistor drive circuit.

It is not FAIL SAFE when a tube fails.
