I recently completed my 50MHz 4CX1000A amplifier. However the Eimac pull I
have had for a while suffers from excessive secondary emission.
The question. I have recently obtained a NOS 4CX1000A. However, despite
being offered as an "Eimac" NOS, both the valve and the original box are
branded General Electric. Does anyone have any views as to the
quality/specification of a valve such as this that is non Eimac branded?
