The Henry 2K Classic X heavy duty is now useable it seems. It is going
to need a complete strip down and cleaning, a sort of mini restoration
but it does look as if it is going to be a very nice amplifier when
sorted. Of the two tubes that came with it one is known to be bad. A
little drive causes it to light up like an ultra violet neon tube with a
resounding 'pop' this happens easier at the higher anode voltage and is
generally followed by a series of louder pops and a big 'bang'. I
presume this is a tube fit for nothing other than looking at and as a
result I want to consider how I might best replace it.
The bad tube is an Eimac 3-500Z date code 8849. The good one is also an
Eimac 3-500Z date code 8611.
Should I consider a single tube or only a matched pair?
Is there a preferred supplier? RFP seems to get good reviews.
Will anybodies tubes fit inside the glass chimneys?
Thanks
