RE: JJ EZ81 issues?

JJ rectifiers, along with their Octal signal tubes, have serious reliability issues. Get the Jamona Junk out of there, ASAP. Contact AA sponsor Jim McShane or other reliable vendor and get good EZ81/6CA4 specimens.

To be fair, JJ's Noval signal tubes seem to be much less problematic. Their EL84 is good and people say good things about JJ's 12AT7 and ECC803.

It's possible that the series SS diode tweak linked below could solve the arcing problem, but decent EZ81s are available at relatively reasonable cost. OTOH, the 5AR4/GZ34 situation IS dire enough to make the series SS diode tweak truly important.
