[DIY] OT: Tube amp disaster

[Martin Czech]

When building some low power stuff with a circuit flaw: no problem.
A PA will explode. Therefore I use some metall film resistors in the
drain/collector/anode circuitry, I choose them so that the quiescent
current plus some tolerance will just not blow the resistors.  Now I
can turn it on, if there's something wrong, the resistors blow...
and I have a second chance to figure out why...  Of course this will
not prevent any wrong mouted polarized cap to blow in my face...
